Biosensors based on gold nanostructures

Optical Biosensors Based on Semiconductor Nanostructures

The increasing availability of semiconductor-based nanostructures with novel and unique properties has sparked widespread interest in their use in the field of biosensing. The precise control over the size, shape and composition of these nanostructures leads to the accurate control of their physico-chemical properties and overall behavior. Furthermore, modifications can be made to the nanostruc...

Protein Biosensors Based on Conical Gold Nanotubes

There is increasing interest in using nanopores as the sensing elements in biosensors [1]. The nanopore most often used is the α-hemolysin protein channel, and the sensor consists of a single channel embedded within a lipid bilayer membrane. An ionic current is passed through the channel, and analyte species are detected as transient blocks in this current associated with translocation of the a...

Evolution of gold nanostructures on graphene.

or exposure to a hydrogen plasma. [ 5 ] Metal–graphene interactions have been much studied theoretically, in terms of the specifi c sites of the metals on the benzene ring, their binding energies etc. So, for example, center-ring positions (H sites) are predicted as preferred locations for most metals (e.g., Ti, Fe), corner sites directly above C atoms (T sites) for Sb, Sn, and Ni, and bridge s...
