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 (H2O2). Since then, many biosensors have been developed to detect a wide range of biochemical parameters, using a number of approaches, each having a different degree of complexity and efficiency.

Sensors & Transducers Journal, Vol.76, Issue 2, February 2007, pp.935-936 stranded DNA shows long- range electron transfer through π stacks of aromatic rings of base pairs [4142]. The first example of a DNA chip, called the eSensorTM, was produced by Motorola Life Sciences Inc. [43]. eSensorTM 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 GenelyzerTM [45].
Sensors & Transducers Journal, Vol.76, Issue 2, February 2007, pp.935-936 Biological and chemical warfare agents have broad threat spectrum, ranging from relatively simple chemical agents to complex bioengineered microorganisms. Traditional chemical agents (nerve, vesicant, and blood agents) have acute toxicities in the range of 10–3 g/person and are relatively easy to detect.

The level of sophistication, awareness, cost, reliability, availability and marketing are all factors involved in deciding, whether biosensors would become popular in near future.
