Introduction:
Graphical representation of the results of theoretical
modeling showing energy transfer between an excited
dye molecule and a nanoparticle.
Overview:
Materials scientists, as in all other branches, can
be theorists or experimentalists. The theorists either
predict phenomena based on current data and scientific
understanding or explain current experimental observations.
Einstein and Newton were theorists, while Faraday was
an experimentalist. The image above illustrates the
size (a) and distance (d) dependence of rate of resonance
energy transfer (kDA) from an excited dye molecule to
a spherical metal nanoparticle. An understanding of
this kind of energy transfer can be used in spectroscopic
distance measurement, quantitative analysis of organic
molecules and prediction of distance, size and shape
of nanoparticles.
