Biosensors could be a thrilling alternative to the conventional systems for the detection of toxins and pathogens. Biosensors are reliable which allow the specific detection of target analyte at minimum cost. Recent advancement in the field of nanotechnology has been used to develop highly sensitive bio-sensor’s chips by using multidisciplinary approach. This strategy could be seen as a key for developing bio-sensing devices and demonstrates rapid responses combined with high sensitivity and specificity. Indeed, these traits have nearly become standard attributes of this technological development and come up from the extremely high surface and small size nanostructure areas as nanotubes, nanowires and nanoparticles. In view of above, it is acceptable to state that biosensor technology has the prospective to augment the sensitivity and specificity, hasten the detection and enable high-throughput analysis.
