Understanding the mechanism underlying the interactions between inorganic nanostructures and biological systems is crucial for several rapidly growing fields that rely on nano-bio interactions. In particular, the further development of cell-targeted

The effect of thiol and selenol functionalization on the vibrational spectra and photochemical stability of terthiophene based molecular wires was investigated using surface-enhanced Raman scattering (SERS). The molecules were found to exhibit marked

We show that aromatic amino acids on aggregated and immobilized Ag nanocrystals degrade upon laser illumination (λ = 514.5 nm). Surface-enhanced Raman scattering (SERS) data, using tyrosine as the precursor, point to a linear one-photon induced reac

We present a simple method for the optical manipulation and spectroscopy of colloidal silver nanoparticles in aqueous solution using optical tweezers combined with dark-field microscopy. Because of their localized plasmon resonances, single trapped m

We describe laser-induced growth and deposition of gold and silver nanoparticles for use as surface-enhanced Raman scattering (SERS) substrates. The nanoparticles form at a glass surface in contact with an aqueous solution with metal ions and a reduc

The 364-nm negative ion photoelectron spectra of XO and OXO molecules (X = Ni, Pd, and Pt) are reported. The spectra yield the electron affinities (EAs): EA(NiO) = 1.455 ± 0.005 eV; EA(PdO) = 1.672 ± 0.005 eV; EA(PtO) = 2.172 ± 0.005 eV; EA(ONiO)

We use optical tweezers to move single silver nanoparticles into near-field contact with immobilized particles, forming isolated surface-enhanced Raman spectroscopy (SERS) active Ag particle dimers. The surface-averaged SERS intensity increases by a
