Förster resonance energy transfer enhanced color-conversion using colloidal semiconductor quantum dots for solid state lighting [PDF]

, 2009
In this paper, we present Förster resonance energy transfer (FRET)-enhanced color-conversion using colloidal semiconductor quantum dot nanocrystals (NCs) to make reddish-orange light-emitting diodes for use in ultraefficient solid state lighting.

Rational Control of Antibody Orientation for Enhancing Sensitivity and Specificity in Lateral Flow Immunoassays With Clinical Validation

Advanced Healthcare Materials, EarlyView.
Systematic investigation of antibody orientation strategies in lateral flow immunoassays reveals that a para‐substituted (aminomethyl)phenylboronic acid mediated probe (P‐6) combined with a biotin‐streptavidin test‐line modification achieves a synergistic 14‐ to 19‐fold sensitivity gain over conventional conjugation. Furthermore, multiplexed detection,

Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Single‐Particle FRET Probes Heterogeneity in the Ligand Shell of Colloidal Perovskite Quantum Dots

Advanced Materials, EarlyView.
Single‐particle, single‐molecule Förster resonance energy transfer turns dye‐tagged ligands into nanorulers for the otherwise elusive organic shell of CsPbBr3 quantum dots. Distance variations within individual particles reveal pronounced local heterogeneity, while changes in the surrounding ligand chemistry shift the average dye–surface separation ...

Modeling of energy transfer in photosynthetic light harvesting [PDF]

, 2018
In this chapter, we describe how energy transfer in photosynthetic light-harvesting antennae can be modeled using physical models. We perform a quantitative comparison of different energy transfer theories, that is, modified Redfield, standard and ...

Increasing Lipid Nanoparticle mRNA Copy Number Improves Transfection Potency

Advanced Materials, EarlyView.
As lipid nanoparticle (LNP) systems are the leading platform for in vivo nucleic acid delivery, improving transfection potency of these systems is of considerable interest. In this work, we explored a post‐mixing formulation method involving a two‐step buffer exchange that increased the number of mRNA copies within each LNP while reducing the number of

Fluorescence resonance energy transfer (FRET) in chemistry and biology: non-Förster distance dependence of the FRET rate [PDF]

, 2006
Fluorescence resonance energy transfer (FRET) is a popular tool to study equilibrium and dynamical properties of polymers and biopolymers in condensed phases and is now widely used in conjunction with single molecule spectroscopy.

Efficient in‐Plane Exciton Transport in a Discontinuous Layered Lead‐Bromide Perovskite

Advanced Materials, EarlyView.
A new class of two‐dimensional lead‐bromide perovskite based on monovalent 4‐aminomethylbenzoic acid cations is presented, featuring a discontinuous inorganic layer. Despite the discontinuous lattice, transient photoluminescence microscopy demonstrates efficient though strongly anisotropic in‐plane exciton transport.

Sensor based on Förster resonance energy transfer with quantum dot

, 2012
Förster resonance energy transfers (FRET) are based on the nonradiative transfer of energy between a donor and acceptor dye in the distance 1-10 nm. With respect to this, quantum dots (QDs) with a high absorbance can serve as suitable donors of energy ...
