Using microfluidics for detecting cancer cells in blood

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.

IMG Seminar Series: "Designing Hybrid Microstructures for Wicking Applications" and "Magnetic Assembly and Cross Linking of Nanoparticles for Releasable Magnetic Microstructures"

Event date: 
Fri, 10/30/2015 - 3:45pm to 5:00pm

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.

IMG Seminar Series: "An introduction to conventional machining concepts and techniques of common engineering materials" and "A MEMS mirror submerged in liquid for wide-angle scanning"

Event date: 
Fri, 10/16/2015 - 4:00pm to 5:00pm
Rob Carroll will give a talk entitled "An introduction to conventional
machining concepts and techniques of common engineering materials." It
will cover basic tools, terminology, methods, and parameters used in
conventional machining of bulk engineering materials as they relate to
available equipment in the IMG prototyping lab.
Xiaoyang Zhang will discuss "MEMS mirror submerged in liquid for wide-angle scanning." Xiaoyang will introduce a novel, submerged electrothermal MEMS scanning mirror with applications in wide angle optics. By submerging the MEMS mirror into a mineral oil whose refractive index is 1.47, a wide-angle optical scan (>120°) can be achieved at small driving voltage (<10V) due to the angular increase of the “Snell’s window” effect and the large mechanical tilt angle (±18°) of the MEMS mirror.
Food will be provided for $4 to those who sign up on the IMG wiki by 5 pm Friday.

IMG Seminar Series: Tips for Effective Oral Presentations and The Ins and Outs of the IMG Website

Event date: 
Fri, 10/02/2015 - 4:00pm
Dr. David Arnold will give a talk entitled "Tips for Effective Oral Presentation," where he will discuss best practices for delivering high-quality oral presentations, including planning, oral delivery, and graphics.  "Do’s and Don’ts” will be highlighted along with a number of practical suggestions and personal experiences.
Nicolas Garraud and Jason June will give an overview of the IMG website, highlighting the different functions, various content types and how to add content to the webpage and wiki.

IMG Seminar Series: MIST Center - Innovating More than Moore Technologies for Smart Systems in the IoT Era

Event date: 
Fri, 09/18/2015 - 3:30pm

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. 

IMG Seminar Series: Origins of Asymmetry in Ferroelectric Si:HfO2 Thin Films with TaN Electrodes

Event date: 
Fri, 09/18/2015 - 3:30pm

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.

IMG Seminar Series: Acoustic Phonons: from Physics to Engineering Applications

Event date: 
Fri, 09/04/2015 - 3:45pm
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.

IMG Kickoff Meeting

Event date: 
Fri, 08/22/2014 - 5:00pm to 6:30pm

We will hold an IMG Kickoff meeting on Friday August 22nd in Larsen 310, starting at 1 pm, immediately after our Friday BBQ.  This meeting is mandatory for all IMG personnel.  We will provide an overview of IMG to new students, review lab organization/training, emphasize importance of the wiki, and review safety information.
