Jinling Zhang and Kangfu Chen will present on topics related to their research. Food will be provided for $4 to those that sign up on the IMG wiki.
Jinling Zhang
Isolation and enumeration of circulating tumor cells (CTCs) in peripheral blood of cancer patients are potentially useful for detection, characterization, and monitoring of the disease and its subsequent treatment. We have developed microfluidic devices that are capable of efficiently isolating cancer cells from whole blood. The cell capture efficiency is about 90%. The method provides a convenient and cost-efficient alternative for CTCs isolation in clinic samples.
Simulation of the interactions between cancer cells and microfluidic devices
Kangfu Chen
Our interest is to explore the interaction between cancer cell and aptamer functionalized micropost based microfluidic device. We shows the distribution of captured cancer cells around different shaped microposts experimentally. As a comparison of the experiments, a theoretical model was set up. COMSOL was used to show the laminar flow in the microchannel of the device. Based on the flow data, we describe the motion of cancer cells in the micropost patterned microchannel. The interaction between cancer cells and micropost surface was simulated based on adhesive dynamics. Finally, we compare the simulation results with the experimental results.
Saitej Ravi and Camilo Velez will present on topics related to their research, "Designing hybrid microstructures for wicking applications" and "Magnetic Assemblies and Cross-Linking of Nanoparticles for Releasable Magnetic Microstructures." Food will be provided for $3 to those that sign up on the IMG wiki.
Dr. Nishida will present the Multi-functional Integrated System Technology (MIST) Center, a NSF Industry/University Cooperative Research Center led by the University of Florida (UF) with founding partner site, University of Central Florida (UCF), focused on the hardware technologies necessary to propel the next generation of smart mobile sensing/computing/communication systems. The MIST Center is motivated by three major research/industry trends: (1) stepping beyond the current challenge of continued conventional scaling of integrated circuits, a.k.a. Moore's Law, (2) exploring new functionalities at intersections of materials/ processes/ devices /circuits for multi-functional systems, and (3) integrating nanoscale materials into micro/nanosystem manufacturing.
Patrick Lomenzo will present on ferroelectricity in HfO2-based thin films:
Ferroelectricity in HfO2-based thin films offers an intriguing pathway toward the realization of ferroelectric devices for next generation memory technologies. Understanding the reliability characteristics and underlying defects of HfO2 ferroelectrics is of critical importance for its successful adoption in emerging memory devices. The observation of asymmetric ferroelectric properties of HfO2 thin films with TaN electrodes is discussed in the context of charged defects and the chemical properties of the electrode interfaces.
Dr. Tabrizian will present an overview of semiconductor micromechanical resonators and acoustic phonon traps. The phonon-level formulation of vibration modes and dissipation mechanisms will be described. Performance sensitivity of phonon traps to physical interactions will be discussed and followed by demonstration of several applications in environmental sensing and physical gauging. Moreover, temperature and dissipation compensation techniques for realization of highly-stable low-loss micro-resonators for frequency reference purposes will be reviewed.Please join us for our annual IMG Kickoff Meeting at 11:30am in Larsen 310. This meeting is required for all IMG personnel. Pizza will be served.
