Pseudoisocyanine J-aggregate to optical waveguiding crystallite transition: Microscopic and microspectroscopic exploration
Article Abstract:
Optical properties and morphology transformations in individual pseudoisocyanine (PIC) J-aggregates in aqueous electrolyte solutions were explored by fluorescent microscopy and microspectroscopy. The fluorescence spectrum of rodlike crystallites was found to differ from that of stringlike J-aggregate and from PIC crystal powder spectra.

Identification and characterization of active and inactive species for surface-enhanced resonance Raman scattering
Article Abstract:
A correlated surface-enhanced Raman scattering (SERRS) mapping and transmission electron microscopy (TEM) method is used to study the SERRS activity of a statistically significant number of silver nanoparticles. Particles in various states of aggregation were analyzed to establish relative activities.
