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.

Arian Rahimi Awarded IEEE Annual AP-S Doctoral Research Fellowship

Submitted by Sheng-Po Fang on Wed, 10/14/2015 - 4:04pm

Arian Rahimi, current IMG members, have been received the 2015 IEEE Antenna and Propagation Society (AP-S) Doctoral Research Award. The IEEE AP-S awards up to 10 PhD fellowships each year to encourage students to pursue a career in the area of Electromagnetics. The awards are intended to support students involved in project work directed by a faculty member at their institution who is a member of the IEEE Antenna and Propagation Society. The title of his research is: "High Performance Conductor Architectures for Future Communication Systems" under supervision of Dr. Y.K. Yoon.

The award selection is based on creativity and quality of the proposed project, discussion of the technical interests and skills of the student. 

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"

Submitted by Justin Kiehne on Wed, 10/14/2015 - 7:53am
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: MIST Center - Innovating More than Moore Technologies for Smart Systems in the IoT Era

Submitted by Nicolas Garraud on Wed, 09/16/2015 - 3:02pm
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

Submitted by Justin Kiehne on Wed, 09/16/2015 - 2:17pm
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.
