The examples analyzed have been selected at random. They have appeared recently in the lit-
erature. The intention is to provide an idea or perspective of the current trends in the appli-
cation of nanotechnology in the area of biosensors. Other recent applications of
nanotechnology for biosensor applications have been presented at recent conferences. They
include:
(a) Enhanced emission of gold nanoparticle due to electron transfer from surface bound
molecules and its use in pH sensing (
Lee et al., 2009
).
(b) Periodic plasmonic nanostructures as efficient SERS (Surface Enhanced Raman Spectra)
substrates for biosensing (

(c) Composition effect of Ag-Cu alloy nanoparticles on luminescence enhancement/
quenching of vicinal luminophores (
