Standard Silicon CMOS Device uses for developing a Biological Sensor

Abstract

Antibody/antigen concept biological sensors as presented in D. Diamond (1998) have shown a very impressive growth in the last decade due to their high selectivity to specific biomolecules. They can allow fast and early detection of various kinds of illnesses and infections. One of the main challenges in this field is to develop biosensors that can be easily inserted within the human body and act as "illness or body malfunction detectors" by reacting to changes in antibody concentration. An important issue facing researchers in this aspect is to build biosensors as stated in K. Gartsman et al. (1998) by using known and inexpensive technologies presented in D. G. Wu et al. (2000). The use of silicon (Si) is very attractive in this sense due to its low price and high reliability
