This paper examines the contribution of counterion motion to the electric-field dynamics in the interior of DNA. The electric field is measured by a coumarin fluorophore that is synthetically incorporated into an oligonucleotide, where it replaces a

Synthetic oligonucleotides with a fluorescent coumarin group replacing a basepair have been used in recent time-resolved Stokes-shift experiments to measure DNA dynamics on the femtosecond to nanosecond timescales. Here, we show that the APE1 endonuc

Gold nanorods have been prepared in aqueous solution using a seed-mediated growth approach in the presence of surfactant. We observe the formation of liquid crystalline phases in concentrated solutions of high aspect ratio (13–18) gold nanorods by

We observed anisotropic chemical reactivity of gold spheroids during cyanide dissolution and reaction with persulfate. Cyanide dissolution of 2−5 aspect ratio spheroids (with 12−30 nm short axis) starts at the ends of the long axis and leads to i

We have examined the adsorption of short 16 base pair DNA to 14 nm protein-sized gold particles using surface-enhanced Raman spectroscopy and electronic absorption spectroscopy. In the presence of KCl, we find greater Raman enhancement of adenine and

Central to the concept of seed-mediated growth of nanoparticles is that small nanoparticle seeds serve as nucleation centers to grow nanoparticles to a desired size. We have examined this common assumption in a model system, the wet chemical synthesi

Gold nanorods with aspect ratios of 4.6 ± 1.2, 13 ± 2, and 18 ± 2.5 (all with 16 ± 3 nm short axis) are prepared by a seeding growth approach in the presence of an aqueous miceller template. Citrate-capped 3.5 nm diameter gold particles, prepared

Silver and gold nanorods with aspect ratios from 1 to 16 have been used as substrates for surface enhanced Raman spectroscopy (SERS) in colloidal solution. The nanorod aspect ratio is varied to give different degrees of overlap between the nanorod lo

The 1 - 100 nanometer size range encompasses the dimensions of proteins and DNA. In this size range the bulk properties of inorganic materials become influenced by quantum mechanical effects and become size-dependent. Semiconductor nanoparticles are
