This idea was commercially exploited in 1975 with the successful launch of the Yellow Springs Instrument Company’s glucose analyzer based on the amperometric detection of hydrogen peroxide (H O ). Since then, many biosensors have been developed to detect a wide range of 2 2 biochemical parameters, using a number of approaches, each having a different degree of complexity and efficiency. Recently, the m

Biosensors in Health Care and Diagnostics With rising healthcare costs and to improve patient care, diagnostic laboratories have been challenged to develop new tests that are reliable, cost–effective and accurate and to optimize existing protocols by making them fa

The first example of a DNA chip, called the eSensorTM, was produced by Motorola Life Sciences TM Inc. [43]. eSensor bioelectric chips also successfully detected 86% of the HPV types contained in clinical samples[44]. Toshiba’s electrochemical DNA hybridization detection system is called the TM Genelyzer [45]. It

Traditional chemical agents (nerve, –3 vesicant, and blood agents) have acute toxicities in the range of 10 g/person and are relatively easy to detect. Emerging chemical agents (toxic chemicals and aerosols) and bioregulators (neuropeptides and psychoactive compound
