Effective Multistep Exciton Delivery Through DNA-based Photonic Wires

Spillmann C.M., Buckhout-White S., Ancona M.G., Cunningham P.D., Melinger J.S., Goldman E.R., Medintz I.L., Naval Research Laboratory, US

Energy manipulation at the nanoscale is a key requirement to develop next-generation nanotechnologies ranging from biosensing to light harvesting, yet the design rules of these nanoscale systems must first be optimized to accomplish their intended [...]

Small Photostable Photoswitchable Quantum Dots as Nanotools for Live Cell Imaging

Díaz S.A., Jovin T.M., Jares-Erijman E.A., University of Buenos Aires, CIHIDECAR, CONICET, AR

We have developed a novel surface architecture for the generation of biocompatible and stable photoswitchable quantum dots (psQDs). The system is based on Förster Resonance Energy Transfer (FRET) from a QD donor to diheteroarylethenes photochromic [...]

Fast and Easy Detection System of Protein Glycosylation by Using Resonant Energy Transfer between Nanoparticles

Oh E., Lee D., Kim H-S, Korea Advanced Institute of Science and Technology, KR

We construct the new glycosylation detection system using Resonance Energy Transfer (RET) between gold nanoparticles (AuNPs) and semiconductor quantum dots (QDs). RET can be induced by biomolecular interactions between concanavalin A (conA)-conjugated AuNP (conA-AuNP) as [...]

Electrophoretically Actuated Nanoscale Optoentropic Transduction Mechanisms

Sullivan B., Dehlinger D., Zlatanovic S., Esener S., Heller M.J., University of California San Diego, US

We have identified a novel oscillatory optoentropic transduction mechanism that may enable modern communications theory to augment DNA and protein target detection within complex biological samples. More specifically, we have shown that electric field driven [...]

Dynamical Properties of Supported Membrane Junctions

Kaizuka Y., Groves J.T., University of California-Berkeley, US

We have recently introduced a supported membrane junction system. The junction consists of a conventional supported bilayer membrane, on top of which a second bilayer membrane is deposited by rupture of a giant vesicle. This [...]
