Chiral templating of self-assembling nanostructures by circularly polarized light
The high optical and chemical activity of nanoparticles (NPs) signifies the possibility of converting the spin angular momenta of photons into structural changes in matter. Here, we demonstrate that illumination of dispersions ...
Controlled Angiogenesis in Peptide Nanofiber Composite Hydrogels
Multidomain peptide (MDP) nanofibers create scaffolds that can present bioactive cues to promote biological responses. Orthogonal self-assembly of MDPs and growth-factor-loaded liposomes generate supramolecular composite ...
Nanofibrous Snake Venom Hemostat
Controlling perioperative bleeding is of critical importance to minimize hemorrhaging and fatality. Patients on anticoagulant therapy such as heparin have diminished clotting potential and are at risk for hemorrhaging. ...
Chiral and Achiral Nanodumbbell Dimers: The Effect of Geometry on Plasmonic Properties
Metal nanoparticles with a dumbbell-like geometry have plasmonic properties similar to those of their nanorod counterparts, but the unique steric constraints induced by their enlarged tips result in distinct geometries ...
Circular Differential Scattering of Single Chiral Self-Assembled Gold Nanorod Dimers
Circular dichroism spectroscopy is essential for structural characterization of proteins and chiral nanomaterials. Chiral structures from plasmonic materials have extraordinary strong circular dichroism effects compared ...
Highly Angiogenic Peptide Nanofibers
Major limitations of current tissue regeneration approaches using artificial scaffolds are fibrous encapsulation, lack of host cellular infiltration, unwanted immune responses, surface degradation preceding biointegration, ...
