The BBB is composed of endothelial cells with distinct tight junctions, a specialized basement membrane, pericytes and astrocyte endfeet. Interaction of endothelial cells with other components of the BBB, especially pericytes is paramount in maintaining BBB integrity.1 Models of the BBB are commonly used to investigate permeability characteristics of astrocytes, pericytes, and endothelial cells.2–5 In vitro models are commonly composed of brain derived cells of murine, porcine, bovine, or human origin. Permeability of in vitro models of the BBB is typically measured using transendothelial electrical resistance (TEER) or diffusion of a fluorescent marker; both modalities have a direct correlation to paracellular permeability. In the Comparative Blood-Brain Barrier Laboratory, we utilize an in vitro model of the BBB using a transwell system composed of mouse derived pericytes6, endothelial cells, and astrocytes (Figure 1). In this system, 20,000 astrocytes are placed on the base of a 24-well plate, 20,000 mouse brain derived pericytes on the base of the transwell insert (Corning), and 20,000 mouse brain derived endothelial cells on the apical surface of the transwell insert (Figure 2a). This BBB model was validated by measuring permeability for seven days in brain derived pericytes and endothelial cells with TEER. Within three days, many cells showed evidence of apoptosis. Our laboratory is most interested in alterations of the blood-brain barrier in brain metastases of lung cancer and the formation of the blood-tumor barrier (BTB).7 An in vitro model of the BTB has been established by co-culturing tumor cells, of any origin, with brain-derived astrocytes in the base of a 24-well plate (Figure 2b). In our models of the BBB and BTB, TEER and diffusion of fluorescence dye are the primary modalities used to evaluate permeability. To measure TEER, two linear electric probes attached to an EVOM2 Volt-Ohm Meter (World Precision Instruments) are placed in the upper compartment of the transwell and in the basal compartment of the well. The electric probes are stabilized and a numerical reading is displayed on the Volt-ohm meter representing TEER. In vivo, TEER of a normal rat brain is approximately 1000 ohms/cm2. TEER measurements in the in vitro BBB model vary widely, but are typically measured between 100-3000 ohms/cm2 depending on culture conditions, cell seeding density, and cell origin. Analysis of permeability via diffusion of fluorescence dye, is determined by calculating the diffusion of a fluorescent dye from the apical compartment of a transwell to the basal compartment. The relative fluorescent units (RFU) of the fluorescent dye of the basal compartment is calculated using a spectrophotometer. A “gold standard” does not exist for an in vitro model of the BBB; however, the parallel analysis of TEER and diffusion of fluorescent markers provide the best analysis of permeability of an in vitro model of the BBB and BTB using a transwell system. The use of the in vitro models of the BBB and BTB provide a primary system to evaluate permeability and efficacy of novel therapeutic compounds that may have an effect on metastatic or primary brain tumors in vivo.

The technology has numerous applications in medicine, e.g. regenerative medicine for the need of tissues and organs suitable for transplantation. 3D printing provides unprecedented control over scaffold architecture, including the geometry of the culture that may influence cell and tissue behavior. The study in the highlighted article examined how the geometry of the culture in scaffold may affect the growth and maturation of ovarian follicles as well as the development of a bioprosthetic ovary to restore ovarian function. The work was done in mice. Description of the article of interest: Laronda MM, Rutz AL, Xiao S, Whelan KA, Duncan FE, Roth EW, Woodruff TK, Shah RN4. A bioprosthetic ovary created using 3D printed microporous scaffolds restores ovarian function in sterilized mice. Nat Commun. 2017 May 16; 8:15261. Scaffolds with different pore geometry were generated by laying a layer of printed gelatin over the layer underneath at the angle of 300, 600 or 900. In 3D confocal image, 300 and 600 scaffolds were observed to have extended corners and another strut underlying the pore, while 900 scaffolds possessed shallow corners without any underlying struts (Figure 1). In vitro, the ovarian follicles thrived best in 300 and 600 scaffolds as compared to the 900 scaffold. Moreover, follicle survival significantly increased with the number of contacts between each follicle and scaffold. When seeded into 300 and 600 scaffolds, each follicle was most likely to have two or three contact points with the scaffold whereas it had mostly one contact point in 900 scaffolds. The 300 and 600 scaffolds provided corners that created contacts with follicles on multiple sides while 900 scaffolds had an open porosity that limited follicle–scaffold interaction. Adhesion of cells, located at the periphery of the follicle, to the scaffold was evidenced by the presence of actin filaments along the surface of the elongated cell bodies and by cell–matrix focal adhesions visualized by staining for the cytoskeletal protein, vinculin. Steroidogenesis is one of major processes occurring within the ovarian follicles that converts cholesterol into steroid hormones, such as estradiol and progesterone. Follicles cultured in the 300 and 600 scaffolds, but not the 900 scaffolds secreted an increased amount of estradiol guiding the follicles toward terminal differentiation and ovulation in vitro, as indicated by the release of mature eggs with extruded polar bodies. The results indicate that the 300 and 600 scaffold architectures support hormone production, oocyte maturation and ovulation. The 300 scaffold were implanted within the ovarian bursa of adult ovariectomized mice (both ovaries were surgically removed). The follicle-seeded scaffolds became highly vascularized and ovarian function was fully restored. Moreover, pups were born through natural mating and thrived through maternal lactation. These observations support the possibility for the bioprosthetic ovary to restore organ function in mice. Comments from 3D3C: 3D printing is rapidly evolving to become a technology with numerous medical applications. There are, however, gaps in information regarding the impact of scaffold architecture on tissue geometry that might, in turn, influence the physiology and function of cells and tissues in contact with the scaffold. The present study is one of a few reports published so far on this issue and it confirms the critical role of tissue geometry influenced by the printed scaffolds for cell and tissue function. Indeed, based on their observations, the authors proposed that the follicles cultured in vitro required multiple contacts with the strut of the scaffolds to maintain a spherical shape, hence enabling cell survival. The exact shape of the follicles within the three scaffolds, however, was not illustrated with actual measurements. These findings will be useful for the future design of effective scaffolds and the improved medical use of 3D printing.

[BIRCK NANOTECHNOLOGY CENTER][http://www.purdue.edu/discoverypark/resources/toolkit/files/logo/di…] Dear Birck Research Community, The business office and engineering organizations have just completed an analysis of current recharge rates. A few rates were found to be incorrect due to recent service contract price changes, usage rate adjustments, etc. A revised rate sheet is being completed and will be put up on the Birck website by the end of July. We have also added a set of equipment that recently had rates approved. You will find those listed on the new rate sheet as well. In addition, as we do every few years, we are in the process of a full Scifres Rate Review. Once we have that completed, we will notify you of any changes. BNC Management [cid:image006.png@01D3022D.EF003B30] The electrical shutdown will be on Saturday, July 29, 2017, from 7:00 am-11:00 am. Birck's parking lot will be affected, weather permitting. West side gravel parking lot is available for parking. Micron Sweps Our custodial staff professionally cleans the cleanroom surfaces with special 'mops' called Micron Sweps. These expensive & reusable mops are used in conjunction with our UltraPure Water to wipe down all surfaces in the cleanroom on a continual basis. We pay a service to clean the Sweps for us, and the laundering is done in a cleanroom environment at the contracted laundry. Recently someone retrieved a Swep and used it to wipe up something in the cleanroom. Please do not use these Sweps! They are designed only to be used with UPW for cleaning cleanroom floors and walls. Other uses will ruin them at a significant cost to Birck. Thanks for your understanding and cooperation. Birck Management Where can you wear shorts in Birck? There has been some confusion as to where shorts are allowed. Long pants or long dresses and closed toed shoes are required to be worn where the potential exists for chemical use. This would include all general labs, bio-cleanroom, J-bay and SEM prep lab. Shorts are allowed in the cleanroom under your cleanroom garment and in the SEM microscope labs. This is for safety concerns and if you have a question, it will always be best to error on the side of safety and wear what provides the most protection. Stephen Birck Safety Officer NSAC (Nanotechnology Students Advisory Council) is organizing an Undergraduate Research Symposium on Friday, August 4, 2017 from 2 to 4 p.m. in the Birck Atrium. This is a unique opportunity for undergraduates to present their research in front of an audience comprised of graduate students, staff, and faculty and get valuable feedback. Plaques will be awarded to the top three posters as well as certificates to all participants. Please encourage any undergraduates in your respective groups to consider registering using the following link: https://goo.gl/forms/vKZQ1U2Itg8dZyic2. The deadline for registration is Friday, July 28, 2017. Thank you! Sincerely, Deesha Shah Birck Kitchen Friday, July 28 around 2 p.m., the refrigerator and freezer will be cleaned out. Anything that is outdated or looks bad with no label will be thrown away.

Introducing NSAC Journal Club
by Sajid Choudhury 07 Jul '17

07 Jul '17

Dear all, I hope you are doing well. This year, for the first time, we are going to start a Journal Club from Nanotechnology Student Advisory Council (NSAC). *Emroz Khan *is volunteering to lead the effort of the Journal Club. The Journal Club will focus on a specific topic for 6-8 weeks before moving to another topic. Our first topic for the Journal Club will be *Topological Insulators*. The Journal Club kicks off on Friday, July 14, 2017, at 3.30 PM in Birck Atrium. The first talk will be given by *Todd F Van Mechelen* (from Prof. Zubin Jacob's group). He will be presenting a brief history of topological insulators and related concepts, followed by a discussion on a recently discovered topological metal (Weyl semimetal). (https://doi.org/10.1126/ science.aaa9297) The paper is attached to this email. Last year's Nobel prize in physics was awarded for the theoretical discoveries of topological phases of matter. The field is still new and active, and it is believed that organizing a journal club around it should facilitate keeping track of the recent developments as well as expose students from other groups to the basic concepts. Some key features of this journal club are: - Each session would be around 30-45 mins long. - The speakers will be those who are currently active in this field. - A recent paper of substantial impact would be walked through. (Discussion of own research is reserved for NSAC coffee hours) - At least first 10-15 mins will be allocated for common understanding so that people with no background has some takeaway. - The relevant paper will be emailed to everyone at least a couple of days before the talk. - There will be refreshments. We will be sending out following announcements regarding the Journal club to bnc-grad list only. If you are a visiting scholar or faculty who would like to get involved in the journal club, please sign up using the following link: *https://lists.purdue.edu/mailman/listinfo/nsac_jc <https://lists.purdue.edu/mailman/listinfo/nsac_jc>* Date: Friday, July 14, 2017 Time: 3:30pm Place: BNC Atrium Speaker: *Todd F Van Mechelen* Topic: Brief history of topological insulators Best Regards, -Sajid Choudhury President, NSAC

[BIRCK NANOTECHNOLOGY CENTER][http://www.purdue.edu/discoverypark/resources/toolkit/files/logo/di…] Birck Nanotechnology Center Wiki We are pleased to announce the launch of BNCWiki<https://wiki.itap.purdue.edu/display/BNCWiki>, a collaborative knowledge space open to all BNC researchers. Anyone subscribed to BNC-all with a current Purdue Career Account may access, edit, and add pages, upload attachments, and make comments. It is hosted on the wiki software Confluence<https://wiki.itap.purdue.edu/> via ITaP<https://www.itap.purdue.edu/learning/tools/confluence.html>, and offers user friendly editing, easy upload of documents, and granular page access/editing restrictions. We welcome your inputs and comments. What is BNCWiki? The Birck Nanotechnology Center Wiki is an effort to document and centralize the experimental expertise currently spread around the facility in individuals and research groups. BNC researchers are encouraged to contribute their processes, experiences, issues, and knowledge in order to increase the speed, quality, and breadth of research that can take place at Birck. BNCWiki currently contains equipment pages for both fabrication and characterization equipment, with details on capabilities, technological overviews, SOPs, user manuals, processes, and references. Info pages are available for iLab, general issues, standard and contributed processes, and MSDS sheets. A wiki is, by its nature, a work in progress. The success of the project will depend on contributions from students, faculty, and staff. Research groups may host their own pages for more specialized info, access to which can be restricted to the group if desired. Please contact Justin Wirth<mailto:jcwirth@purdue.edu?subject=BNCWiki%20Question> for more info. How can I access BNCWiki? Access the main page here: https://wiki.itap.purdue.edu/display/BNCWiki. Login with your Purdue Career Account login and password. The site is accessible through both desktop and mobile devices. If pages show formatting issues on mobile, either the "View Desktop Version" option in Confluence or the "Request Desktop Site" setting in the mobile browser may improve display. How do I edit a page? To enter edit mode when viewing a page, press either the "Edit" button in the top right corner of the page, or press the "e" button on your keyboard. [cid:image004.jpg@01D2F715.4650CCC0] This will launch the Confluence Editor<https://confluence.atlassian.com/conf61/the-editor-877187526.html>. Page editing is similar to a document editor such as Microsoft Word, with formatting options available on the menu bar at the top of the page. After changes are made, the "Preview" button in the bottom right corner will allow you to view the edit before publishing. Once satisfied with the changes, press the "Update" button in the bottom right corner to publish the changes. How do I add a document? Confluence supports native viewing of PDFs and images, as well as Word, Powerpoint, and Excel files.
