A method for synthesizing composite nanoparticles with a gold shell, an Fe3O4 inner shell,
and a silica core has been developed. The approach utilizes positively charged amino …

Quantitative detection of biomolecules (eg DNA and proteins) has become increasingly
important in a variety of fields, including medical diagnostics, food safety, and anti …

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 …

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 …

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 …

Controlled synthesis of cobalt ferrite superparamagnetic nanoparticles covered with a gold
shell has been achieved by an affinity and trap strategy. Magnetic nanoparticles are …

A major limitation in nanoparticle-based materials chemistry is the lack of suitable assembly
methods for preparing extended two-and three-dimensional architectures with synthetically …

Gold nanoparticles (AuNPs) were anisotropically functionalized with two different
oligonucleotide sequences using magnetic microparticles as geometric restriction templates …

In this study, we report the chemical synthesis and functionalization of magnetic and gold-
coated magnetic nanoparticles and the immobilization of single-stranded biotinylated …

Herein we report the development of a simple, rapid, homogeneous, and sensitive detection
