Reconfigurable Polymer Shells on Shape‐Anisotropic Gold Nanoparticle Cores

Energy transfer between amphiphilic porphyrin polymer shells and upconverting nanoparticle cores in water-dispersible nano-assemblies.

The synthesis of water-dispersible nano-assemblies containing upconverting nanoparticles (UCNPs) and porphyrin molecules using a one-pot method is described. When the nano-assemblies are excited by 980 nm near-infrared light, the intensity of the 'green emission' band of the UCNP is reduced due to a combination of Föster Resonace Energy Transfer (FRET) and emission-reabsorption. This process is...

Gold nanoparticle-polymer/biopolymer complexes for protein sensing.

Nanoparticle-based sensor arrays have been used to distinguish a wide range of biomolecular targets through pattern recognition. Such biosensors require selective receptors that generate a unique response pattern for each analyte. The tunable surface properties of gold nanoparticles make these systems excellent candidates for the recognition process. Likewise, the metallic core makes these part...

Dynamically Reconfigurable Cores

Dynamic reconfiguration of digital circuits on FPGAs has been an area of active research for the past decade. The identification of generic classes of circuits that would benefit from being dynamically reconfigured remains a key, open problem. We report on an investigation of the application of dynamic reconfiguration to programmable, multi-function cores (PMCs). An abstract analysis of the tec...
