Self-assembly of silver nanoparticles through functionalization with coumarin-thiazole fused-ring thiol

Fast pH-assisted functionalization of silver nanoparticles with monothiolated DNA.

Attaching monothiolated DNA to silver nanoparticles has been achieved at pH 3.0 in 30 minutes and difficulties associated with DNA attachment to AgNPs at neutral pH have been revealed by studying DNA adsorption kinetics.

Functionalization of Polymer Nanoparticles by Thiol-Ene Addition

Syndiotactic 1,2 polybutadiene nanoparticles (volume average diameter 13 nm) were func tionalized in aqueous dispersion by free radical mercaptan addition. By appropriate choice of both water soluble radical initiator andmercaptan concentration, nanoparticles with a degree of functionalization of up to 85% were prepared using 3 mercaptopropionic acid methyl ester and 3 mercaptopropionic acid. O...

Controlling Assembly of Mixed Thiol Monolayers on Silver Nanoparticles to Tune Their Surface Properties

Modifying the surfaces of metal nanoparticles with self-assembled monolayers of functionalized thiols provides a simple and direct method to alter their surface properties. Mixed self-assembled monolayers can extend this approach since, in principle, the surfaces can be tuned by altering the proportion of each modifier that is adsorbed. However, this works best if the composition and microstruc...

Specific functionalization of CTAB stabilized anisotropic gold nanoparticles with polypeptides for folding-mediated self-assembly

Control of surface plasmon localization via self-assembly of silver nanoparticles along silver nanowires.

A simple and low-cost method to create metal-metal hybrid nanostructures possessing fairly regularly spaced "hot-spots" of surface plasmon resonances is proposed. The nanohybrid structure was prepared via self-assembly during a simple drop-casting procedure, using chemically synthesized silver nanowires and silver nanoparticles prepared in a single batch of a polyol process. Wide field illumina...
