Plasmon induced self-assembly of gold nanorods in polymer films.
Photoactivated orientation of gold nanorods (AuNRs) incorporated into polymethylmethacrylate and SU-8 photoresist films occurs under red light activation. Excitation of the longitudinal surface plasmon resonance band leads to selective orientation of the nanostructures, revealed by a change in the absorption spectra.
متن کاملLigand-mediated self-assembly of polymer-enveloped gold nanoparticle chains and networks.
We demonstrate a universal approach to assemble gold nanoparticles (AuNPs) into ordered robust nanostructures. Colloidal AuNPs are partially coated by thiol-containing ligands and then destabilised into anisotropic superstructures. In situ polymerization of the surface attached ligands produces enveloped nanoparticle networks with retained nanoplasmonic properties and enhanced stability.
متن کاملPolymer-assisted self-assembly of gold nanoparticle monolayers and their dynamical switching†
The topic of tuneable plasmonics has sparked great interest in recent years as it offers realistic hopes for plasmonically active thin films that enable a wide range of applications from variable focus mirrors to biosensing processes such as surface plasmon enhanced Raman spectroscopy and catalysis. However, the fabrication and actuation of ordered thin films of nanoparticles such as gold (AuNP...
متن کاملThermally and photochemically triggered self-assembly of peptide hydrogels.
Self-assembling systems present attractive platforms for engineering stimulus-responsive materials with controlled nanoand microstructures. Recent efforts to design such systems include synthetic block copolymers,1a proteins that self-assemble into hydrogels via leucine zipper motifs,1b cyclic peptides that selfassemble into nanotubes,1c-e and peptides that form fibrillar â-sheet networks.1f-i ...
متن کاملThermally reversible self-assembly of nanoparticles via polymer crystallization.
The directed self-assembly of gold nanoparticles through the crystallization of surface-grafted polyethylene oxide (PEO) in ethanol-water mixtures is described. This process is fully reversible and tunable through either the size of the core or the polymeric coating. Characterization by X-ray scattering and electron microscopy of the self-assembled structures reveals order at the nanoscale, typ...
