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.

Muthusamy Sivakumar has completed his Ph.D degree from Anna University, India in the year of 1998. He has spent 9 years as postdoctoral fellow in different universities such as National University of Singapore and Nagoya Institute of Technology, Japan. He is a recipient of internationally competitive fellowship called JSPS from Japan. Later, he has joined Anna University of Technology, Tiruchirappalli as Assistant Professor in the Department of Nanoscience and Technology. Dr.M.Sivakumar has published more than 30 papers in reputed journals and has attended 50 international and national conferences. He has delivered about 25 international and national invited talks.
