The calculated spectra
for different nanoparticle types clearly reflect the well-known
fact well as the extent of the plasmon enhancement is highly
dependent on the size, shape, and core-shell composition of
the nanoparticles, thus allowing easy optical tunability, which
is lacking in the case of dyes. To aid the selection of an
appropriate nanoparticle for a suitable biomedical application,
a systematic quantitative discussion of the trends in the optical
tunability of nanoparticles follows.
