MEMS(Microelectromechanical systems)









 Biotechnology is the use of biological processes, organisms, or systems to manufacture products intended to improve the quality of human life. Micro-electromechanical systems(MEMS) is a tech- nology that combines computer with tiny mechanical devices such as sensors, valves, gears, mirrors and actuators embedded in semiconductor chips. MEMS is enabling new discoveries in biotechnology such as polymerase chain reaction microsystems for DNA amplification and identification, micromachined, scanning tunneling microscopes, biochips for detction of hazardous chemical and biological agents, and microsystems for high-throughput drug screening and selection. Microfluidics is an exciting new field of science and engineering that enables very small-scale fluid control and analysis, allowing instrument manufacturers to develop smaller, more cost-effective and more powerful systems. With this Lab-on a-chip technology, entire complex chemical management and analysis systems can be created in a microfluidic chip and interfaced with, for example, electronics and optical detection systems.
 Microfluidics is being used to develop new methods to analyze
and control biochemical systems. 
 Engineering challenges include the realization of optimized processes in mixing, reaction, seperation, pre-concentration, and detection of chemical species.












CFD(Computational Fluid Dynamics) & Chaos









 This laboratory performs a detailed and extended research on microdevices, microfluidics and micro mixing principles. CFD is the research tool used in the lab. 
This involves use of highly sophisticated computer for solving complex fluid flow problems in the micron and submicron level.   A major goal of our lab is the exploitation of the physical regi- mes associated with micro and nano scale devices in order to achieve new functionality.
 At present, research on electromagnetic effect on microfluidics, flow inside microchannels are under progress.
