Biosensor for detection of bacteria with probiotic potential and food pathogens

Abstract

The exploration for novel nano-sensors has enhanced significantly representing an incredible alternative for the development, speedy, and inexpensive bio-sensing strategy. Due to their low detection volumes, reduction of detection time, high specificity and user- friendly applicability, nano-bio sensors have raised the interest of the scientific community. Nanomaterials are now being used to develop biosensors thatexhibit superior sensitivity and uniqueness with applicability in research investigations, food contamination detection, detection of potential probiotic bacteria, etc. Detection of food contamination is of major significance and concern in areas like healthcare, agriculture, beverage, and fermentation industries. Distinctive biosensing technologies have already been developed for instant monitoring of microbes, food contaminants depending upon the application of nanomaterial. A wide range of nanomaterials, for example, gold nanostructured materials, carbon Copper and silicon nanotubes, GeO2/SiO2 matrix, nanoparticles, nanowires, TiO2 nanowire, nano-electrode, and nanostructured material arrays are performing an essential role in the bio-sensing application in food pathogen detection and probiotic bacteria detection.Nanosensors merges the principles of information technology and molecular biology proves essential in facilitating immediate detection of foodborne pathogens, contaminants, hence reducing the health risk and medical costs related to foodborne illness.This chapter aims to encompass the types of emerging nanosensors based on different detection technology, their commercial applications, recent advancement in food contamination detection and their future prospects.
