This was an international industry-academia collaboration that led to an FDA-cleared medical device that is used clinically. The presentation will also describe a computer-controlled microfluidic pumping technology that was developed by an undergraduate student, then applied to biomedical needs such as microfluidic embryo culture, another device that has been tested clinically. A final microfluidic topic will be efforts, including work by Ga Tech Undergrads, to construct microscale intestine models with human intestinal organoids and a microbiome.
- The presentation will also give a short preview of two components of the planned exchange program:
- Mentoring opportunity for GRADUATE STUDENTS to host a Japanese Undergrad Researcher for ~5 weeks in Aug/Sept 2020. Mentors will be invited to cultural exchange programs and also receive $3000 to be used for travel to scientific conferences or materials and supplies for the lab.
- Another component is an opportunity for Georgia Tech BME UNDERGRADS to do a fully-sponsored Global Internship Program (GIP) in Japan in summer 2020 (mid May - July) doing research at leading Japanese Universities.
Ultrafast microfluidic cell compression for convective intracellular macromolecule delivery: Anna Liu - Ph.D. candidate The Wallace H Coulter Department of Biomedical Engineering, Georgia Tech
- Efficient intracellular delivery of target macromolecules remains a major obstacle in cell engineering, cell labeling, and other biomedical applications. Our lab has discovered the unique cell biophysical phenomenon of convective intracellular macromolecule delivery using mechanically induced, transient cell volume exchange. Ultrafast microfluidic cell compressions are used to cause brief, deformationinduced cell volume loss followed by volume recovery through uptake of surrounding fluid. Macromolecules suspended in the surrounding fluid enter the cell on convective fluid currents. We harness this cell volume exchange behavior for high-throughput, convective intracellular delivery of large macromolecules, including plasmids (>10 kb) and particles (>30 nm), while maintaining high cell viability (>95%). Successful experiments in transfection and intracellular labeling demonstrate potential to overcome the most prohibitive challenges in intracellular delivery for cell engineering
Investigating health effects of aerosol particles on single-cells in a high-throughput air-liquid interface platform: Jenni Li - Undergraduate researcher
- Air pollution and its detrimental health effects have been an increasingly alarming concern for the world. Cardiovascular diseases, chronic respiratory diseases, and different types of cancers can all be linked to air pollution effects. Furthermore, over 4 million people die per year from the direct effects of ambient particulate matter. One conventional method for studying the health effects of aerosol particles is to collect particulate matter (PM) from the atmosphere, resuspend the PM in cell culture media, add the PM/media to cell cultures, and assess single cell oxidative stress. However, this method does not resemble the in vivo conditions of alveolar macrophages. Alveolar macrophages are found in the alveoli of the lungs where the oxygen and carbon dioxide exchange between blood and air takes place and are a key cell type that is affected by PM. In this project, we aim to create a microfluidic air-liquid interface environment that mimics how alveolar macrophages are exposed to PM in order to study effects of PM at a single-cell level. Utilizing a microfluidic platform provides uniform microenvironment and enables high-throughput and high content single-cell analysis for hundreds of cells. We adapted a previously developed microfluidic single-cell analysis technology and developed a method for exposing cells to an air-liquid interface. We then characterized cells by microscopy and LIVE/DEAD staining to assess if cells remain viable during air exposure. Following this validation of the air-liquid interface platform, we will use it to study the single cell responses of intracellular reactive oxygen species in exposure to aerosol particles
ED/PHO/GEDC Seminar: Mixed-Domain Nano-Systems for Integrated Radio Frequency Communication Applications
September 18, 2019 @ 11:00AM-12:30PM | Technology Square Research Building, 1st Floor Auditorium | 85 5th Street NW Atlanta, GA 30308
Please join us for a seminar in partnership with the Georgia Electronic Design Center. Dr. Roozbeh Tabrizian from the University of Florida will give a talk on the mixed-domain nano-systems for radio frequency communications.
The Smart Connected World paradigm is based upon communication hardware that meet stringent requirements on performance, size, weight, and power consumption (SWaP). For example, the new wireless protocols (i.e. 5G and beyond) enforce extreme enhancement of spectrum use efficiency, bandwidth, and reconfigurability, which requires substantial transformation of available RF front-end modules. In this talk, I will discuss mixed-domain RF nano-systems that are realized at the intersection of semiconductor electronics, nano-acoustics, and atomic-layered ferroelectrics. These systems are poised to enable unprecedented functionalities, in ultra-miniaturized SWaP, for emerging communication applications. In the first part, I will discuss the design and fabrication innovations that pave the way for monolithic integration of nano-mechanical spectral processors on semiconductor platforms. Specifically, I will introduce the fin-based high-Q M/NEMS resonator technology and atomic-layered ferroelectric-hafnia transducers as the two enablers for realization of the first integrated cm- and mm-wave spectral processors. In the second part, I will present novel semiconductor-based RF components that exploit linear and nonlinear interactions of acoustic waves and electric fields to realize previously unavailable processing capabilities at the chip scale. In this context, I will go over the design and implementation of acousto-electric amplifiers, non-reciprocal filters, frequency reference chains, and instinctually adaptive limiters, and discuss their application space.
Roozbeh Tabrizian received his B.S. in Electrical Engineering from Sharif University of Technology, Tehran, Iran, in 2007, and Ph.D. in Electrical and Computer Engineering from Georgia Institute of Technology, 2013. In 2014, he joined the Department of Electrical Engineering, University of Michigan as a Postdoctoral research fellow. In August 2015, he joined the Department of Electrical and Computer Engineering, University of Florida as an Assistant Professor.
His research at the University of Florida involves linear, nonlinear, and nonreciprocal nano-acoustic devices, RF M/NEMS, mixed-domain nanosystems for time-keeping / transfer, frequency reference, and spectroscopy applications, and micro- / nano-fabrication technologies. Dr. Tabrizian is the recipient of DARPA Young Faculty Award (2019) and NSF CAREER award (2018). His research has resulted in more than 50 journal and conference papers, 2 book chapters, 3 published patents and 10 patent applications.

A Physical Organic Chemist's Approach to Precursors for the Deposition of Inorganic Nanostructures
September 19th, 2019 @ 10:00AM | Marcus Nanotechnology Building 1117-1118 | Georgia Institute of Technology
Abstract: Nanostructured materials can be deposited from organometallic and inorganic precursors by a variety of techniques including chemical vapor deposition (CVD) and focused electron beam induced deposition (FEBID). Precursor choice requires consideration of the reaction conditions and possible decomposition mechanisms for the particular method. Mechanism-based design of precursors for CVD will be presented in case studies for contrast with strategies for design of FEBID precursors. The examples for CVD will be low temperature deposition of tungsten carbonitride (WNxCy) and tungsten oxide (WOx) films and nanoparticles. In contrast, the conditions for FEBID are surface reactions under high electron flux, necessitating different precursor design rules. Strategies for adapting selected CVD precursor types for FEBID and efforts to identify privileged ligand classes and optimal coordination spheres for FEBID precursors will be discussed in the context of studies on Ru, Pt and Au complexes
