Nanobiosensors for Pathogenic Agents Detection

Conventional methods to detect pathogenic microorganisms can be wasteful, expensive, and not very sensitive. Due these limitations, approaches based on nanotechnology the development of new diagnostic tests are emerging as alternative methods. Resulting from unique electrical, magnetic, luminescent, catalytic properties nanomaterials, rapid cost-effective have been developed recognize presence microbial pathogens or some their components in different samples. The purpose this review is provide an overview update regarding use several nanomaterials biosensors, among which gold nanoparticles, carbon nanotubes, magnetic quantum dots. application biosensors has opened a interdisciplinary frontier between biological detection materials science.
