In the current scenario, COVID-19 has created a havoc negative impact on lives of people, which have triggered research interest design and development sensitive, low cost power-efficient sensors for detecting wide variety biomolecules. Here, novel hetero dielectric (HD) material (HM) Bio-RFET based sensor is proposed works as n or p MOSFET TFET hence, capable to sense biomolecules through labe...

A fluorescence probe is a molecule that plays important role in sensing various biological [1-5] and chemical processes [610]. This includes cell imaging applications [1,2,5], studying the bio-molecular interaction (e.g. protein-lipid, protein-protein, small molecule-protein interaction) [6-10], characterization of microenvironment of organized assemblies [9,10], etc. The development of two pho...

In this article, a charge-plasma (CP)-based double gate schottky barrier FET structure has been investigated using dielectric controlled biomolecule sensor. The use of Hafnium as charge plasma at the source side encourages an n + in un-doped silicon region, which expressively decreases Schottky thickness. oxide below Metal M1 and M2 is etched out to create nanogap openings for finding. Here, ex...

This work describes a label-free microarray analysis technique capable of detecting biomolecule target interactions with probes being anchored with a new linker-diluent system on indium-tin-oxide. The method is based on the differential work function characteristics of the substrate measured by a scanning Kelvin nanoprobe in terms of contact potential difference signals.

A dispersion-dominated colorimetric approach for the recognition of carbohydrates based on biomolecule-responsive AuNPs is presented. Taking advantage of the unique dual-responsiveness of smart copolymers, the aggregation and dispersion of AuNPs can be modulated by both temperature and different kinds of carbohydrates, giving rise to a novel chromogenic mechanism for the recognition and testing...
