Assembly of Gold Nanoparticles on Gold Nanorods Using Functionalized Poly(N-isopropylacrylamide) as Polymeric “Glue”

Telechelic polymers from reversible-deactivation radical polymerization for biomedical applications

“…Reduction can also be carried out in situ during AuNP formation. This approach has naturally been extended to gold surfaces 82,83 or gold nanorods (AuNRs), 84,85 in a rather straightforward manner.…”

“…15). 84 Given these unique properties, this nanomaterial assembly could be of interest in the field of biomedicine and biosensing. Heterotelechelic polymers are naturally of great interest to immobilize proteins at the surface of gold nanoparticles for potential applications in drug delivery or biosensing.…”

Phase separation in mixed polymer brushes on nanoparticle surfaces enables the generation of anisotropic nanoarchitectures

“…unique surface-enhanced Raman and plasmonic properties. [9][10][11][12][13][14][15] One key parameter of nanoarchitectures of this type is the distance between the central scaffold particle and the attached functional units. This parameter can be controlled (on the respective length scales) by varying the length of shortchain alkyl linkers (B10 0 nm), 16 and also by using rigid DNA origami scaffolds (up to B10 2 nm).…”

Plasmonic Nanostructures as Surface-Enhanced Raman Scattering (SERS) Substrate for Protein Biomarker Sensing

“…Single-particle SERS obtained from the trimer nanoantenna showed distinct peaks from the Raman molecule (PCEPE), which are correlated with the density functional theory (DFT) calculations (Figure 3c-e). Plasmonic nanostructures with multiple hot-spots have been reported with the satellite nanostructures by using either gold sphere or gold nanorods as the core [51][52][53]. To obtain the high orders of nanoassemblies, the linker is the key to connect the nanoparticles.…”
