Abstract

To develop a novel optical affinity biosensor technology that will enable fast, sensitive and specific detection for identification for food borne microbes (food contaminations). Our recent research on biosensors focused on the development of bionanomaterials that truly mimic the natural iridescent colour. Synthetic peptide based nanotubes that have utilized for the futuristic applications. Langmuir-Blodgett films based peptide nanotubes are deposited on silicon substrates, which have the ability to act as iridescent colour sensor. The selective architecture of peptide sequence has been chosen based on their functional groups which can detect the target’s membrane components. The colour is formed by coating of uniform nanostructures through interference of light. The simple concept of these iridescent colour changes are influenced by several factors such as refractive index of the probe materials, mounting the nano ordered film thickness, number of layers and the angle of the incoming light. Visible detection based on iridescent colour (Scheme 1) is appealing and might have potential applications in the area of food contamination.
