We report a new strategy for preparing silver nanoparticle− oligonucleotide conjugates that
are based upon DNA with cyclic disulfide-anchoring groups. These particles are extremely …

This paper reviews techniques currently available for size-and shape-selective purification
of nanoscopic objects. The methods discussed range from variants of familiar …

Producing monodisperse nanoparticles is essential to ensure consistency in biological
experiments and to enable a smooth translation into the clinic. Purification of samples into …

The development of appropriate in vitro protocols to assess the potential toxicity of the ever
expanding range of nanoparticles represents a challenging issue, because of the rapid …

Color is everything: Hg 2+ in aqueous media is detected by the formation of thymidine-Hg 2+-
thymidine coordination complexes, which raises the melting temperature of the DNA …

DNA nanowalkers moving progressively along a prescribed DNA track are useful tools in
biosensing, molecular theranostics and biosynthesis. However, stochastic DNA …

Gold nanoparticles (AuNPs), the huge potential functional nanoparticles in scientific
research, have attained tremendous interest for their unique physical–optical property since …

Coupling of localized surface plasmon resonances results in singular effects at the void
space between noble metal nanoparticles. However, implementation of practical …

Here we report a “blue-to-red” colorimetric method for determination of mercury ions (Hg2+)
and silver ions (Ag+) based on stabilization of gold nanoparticles (AuNPs) by redox formed …

Nanotechnology has virtually exploded in the last few years with seemingly limitless
opportunity across all segments of our society. If gene and RNA therapy are to ever realize …
