FET DNA Sensor Array and Readout Circuitry
Conventional DNA (Deoxyribonucleic acid) detection method using fluorescent dye
is not always suitable for portable low-cost lab-on-a-chip applications. An
alternative detection method using FET (Field Effect Transistor) which is
applicable to detect the intrinsic charge of DNA is most attractive way to
implement in lab-on-a-chip platforms. In this work, we will design a high
sensitivity FET DNA sensor which consists of two dimensional arrays and
includes differential detection circuit to be able to readout the current
difference between the sensing and reference transistors.
Generic Micro Cell Chip for Muscle Stem Cell Applications
In this project we develop a micro-platform for clonal analysis of muscle stem
cells for possible clinical applications in therapeutic stem cell
transplantation for various diseases, including muscular dystrophy, heart
failure and urological dysfunction. We will find optimal conditions for muscle
stem cell culture by using a multi micro-well chip with the capability of
loading, culturing and monitoring stem cells in selected micro-wells. This
microfluidic chip will be designed, fabricated and validated in this research.
Development of Sensors for Human Interface
Today, interface for mobile devices such as PDAs, cellular phones or portable
music devices has become smarter than ever. Since the core technologies which
enable their basic functions for those devices become mature and popular these
days, the competitiveness of such products does not depends on core
technologies only. Rather, design and interface technology are becoming more
important as a key factor which determines market success. In this work, we
explore new human interface schemes and related microsensors.
The Neural Nanoprobe: Wireless Transmission of Neural Signals within the Brain
Damage to the nervous system can result in diverse disorders, ranging from
headaches, Alzheimer, Parkinson, epilepsy, to multiple sclerosis. For millions
of people who have suffered from any type of neurological disorders, the result
is a definite degeneration in their quality of life. Treatments for
neurological disorders would be very challenging and risky, but the reward
would be great and there would always be a demand for them. In designing a
treatment, first we need to understand the inner workings of the nervous
system. The key to brain function is an understanding of how the brain
processes information. We design a novel mechanism which will enable the
simultaneous recording of hundreds of neurons simultaneously with sufficient
resolution, and will transmit the signals wirelessly to a central intracranial
way-station, in which low-power implementation is a key feature.
