A study aimed at understanding the factors that control the optical properties of DNA-linked
gold nanoparticle aggregates containing oligonucleotide linkers of varying length (24− 72 …

Herein, we report a new, noncovalent DNA-based strategy for controlling the stepwise
growth of layered nanoparticle structures off of glass surfaces. Others have demonstrated …

Herein, we describe the detailed synthesis of Ag/Au core-shell nanoparticles, the surface-
functionalization of these particles with thiolated oligonucleotides, and their subsequent use …

We find that single-and double-stranded oligonucleotides have different propensities to
adsorb on gold nanoparticles in colloidal solution. We use this observation to design a …

In 1996, we reported a method for utilizing biomolecules, such as DNA, and their molecular
recognition properties to guide the assembly of nanoparticle building blocks modified with …

The structural properties of DNA-linked gold nanoparticle materials were examined using
synchrotron small-angle X-ray scattering. The materials are composed of 12 or 19 nm …

We report end-to-end assembly for tuning the optical properties of a gold nanorod/sphere
based on oligonucleotide hybridization. The rationale behind the selection of the …

The discovery of the DNA-mediated assembly of gold nanoparticles was a great moment in
the history of science; this understanding and chemical control enabled the rational design …

We have determined the minimum number of base pairings necessary to stabilize DNA− Au
NP aggregates as a function of salt concentration for particles between 15 and 150 nm in …

The common drawbacks of current colorimetric sensors using gold nanoparticle aggregation
is its relatively low sensitivity and narrow dynamic range, which restrict their application in …
