Fabrication and electrical characterization of 5-nm polysilicon gaps and their properties are discussed with their application in electrochemical sensors and biomolecule detection. To understand the relationship between the biosensor and nanotechnology we have carried out the fabrication and characterization of nanogap structures for DNA detection. In this paper, 2 mask designs are used. The first...
Nanomaterials such as silica nanoparticles works as sensor when probe hybridized with the target sequence. Due to their large surface area to volume ratio, they can achieve rapid and low cost reactions. They can conjugate with a variety of biomolecules (Proteins, enzymes, peptides, and DNA) and used as fluorescence biomarkers to monitor biological events or identify and detect biological targets....
