Circular dichroism (CD) is the differential
absorption of left- and right-handed circularly
polarized light. This phenomenon is exhibited in the
absorption bands of optically active molecules and
nanoparticles. Magnetic CD spectroscopy serves as an
excellent tool to track and control the distribution
of ions within the spinel lattice of ferrite
nanoparticles assisting in the development of general
preparation schemes of stoichiometrically controlled
multi-cation oxide nanocrystals. The correlation
between natural circular dichroism and plasmonics
gives rise to two different phenomena. An enhanced CD
signal is obtained when chiral molecules are adsorbed
onto noble metal nanoparticles, enabling the
development of a highly sensitive semi-analytical
technique similar to other enhanced spectroscopic
techniques (e.g. SERS, SEIRA, SEF, SEMO). The growth
of silver nanoparticles in a DNA scaffold resulted in
a rather surprising discovery that the nanoparticles
were, in fact, chiral.
