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 ...

Despite tremendous potential of highly sensitive electronic detection of biomolecules by nanoscale biosensors for genomics and proteomic applications, many aspects of experimentally observed sensor response (S) are difficult to understand within isolated theoretical frameworks of kinetic response or electrolyte screening. In this paper, we combine analytic solutions of Poisson-Boltzmann and dif...

Gold nanoparticle (AuNPs) coupled dynamic light scattering (DLS) is a biosensing technique combining the properties of AuNPs with analyte recognition to produce an easy-to-use analytical tool. The principle assay immobilize bioreceptors specific target onto nanobiosensors. When added system, binding protein immobilized leads size shift functionalised AuNPs. This in can be quantified by DLS. It ...

Nanotechnology has emerged as a boon to the society with immense potential in varied area of research and our dayto-day life. The application of nanotechnology for the advancement of biosensor leads to an efficient nanobiosensor with miniature structure as compared to conventional biosensors. Nanobiosensors can be effectively used for sensing a wide variety of fertilizers, herbicide, pesticide,...

The realization of a high-throughput biosensor platform with ultrarapid detection of biomolecular interactions and an ultralow limit of detection in the femtomolar (fM) range or below has been retarded due to sluggish binding kinetics caused by the scarcity of probe molecules on the nanostructures and/or limited mass transport. Here, as a new method for the highly efficient capture of biomolecu...

Acquired immunodeficiency syndrome (AIDS) is a global disease caused by human virus (HIV). About 50 million people have died worldwide due to HIV-1 infection alone. HIV primary sexually transmitted but can also spread via breastfeeding, blood transfer, organ etc. Early detection with the maintenance of only way reduce and severity disease. There are many conventional techniques for virus. Still...
