Many studies have focused on harnessing
the extraordinary optical properties of
noble metal nanoparticles for the development
of biological and chemical nanosensors.
Metallic nanoparticles emulate
surface roughness, facilitating the coupling
of light to surface plasmon polaritons. The
excitation of the plasmons enhances the
electromagnetic field near the surface so
that...
This work exploits the use of noble metal
nanoparticles to achieve sensitive and
selective detection of chemical and
biological analytes. The localized surface
plasmon resonance (LSPR) of these metal
nanoparticles is known to be sensitive to
shape, size, and the local environment.
Ag nanoparticles fabricated using the
nanosphere lithography (NSL)...
