BioMEMS and Microfluidic Devices for Lab-on-a-Chip Applications

Abstract: Since the first introduction in 1970’s, MEMS technology is becoming popular in many different application areas, including military, automotive, and consumer electronics, as it provides cheap, small, and smart sensors and actuators. This technology is especially critical for biomedical applications, resulting in a new research area shortly called BioMEMS. BioMEMS can be defined in general as “devices or systems constructed using techniques inspired from microfabrication that are used for processing, delivery, manipulation, analysis, or construction of biological and chemical entities.” Application areas of BioMEMS range from diagnostics to micro-fluidics, systems for drug delivery, tissue engineering, and implantable systems. One of the most interesting application areas for this technology is the micro total analysis systems (Micro-TAS). Biological samples can be analyzed in a very small area with considerably reduced cost and time, by forming micro-fluidic channels on silicon substrate and combining them with onchip electronics. Some examples for such applications include on-chip electrophoresis systems, polymerized-chainreaction (PCR) units, DNA sequencing chips, and complex lab-on-a-chip devices. There are currently various BioMEMS related projects going on at METU-MEMS, including DNA electrophoresis systems, dielectrophoresis chips for cell seperation, gravimetric sensors for cancer cell detection, microvalves and pumps for lab-on-a-chip systems, and electrochemical sensors for bacteria and
