We investigate the fluorescence from dyes coupled to individual DNA-functionalized metal
nanoparticles. We use single-particle darkfield scattering and fluorescence microscopy to …

Artificial enzymes such as nanozymes and DNAzymes are economical and stable
alternatives to natural enzymes. By coating Au nanoparticles (AuNPs) with a DNA corona …

Current and future diagnostics urgently need imaging agents that are non-toxic and superior
to clinically used small molecule dyes. Herein, we have developed luminescent green light …

A direct estimate of changes in the radiative and nonradiative decay rates of a chromophore
near metal nanoparticles is obtained using a quantum mechanical description coupled to …

Fluorescence-based single-molecule optical detection techniques are widely chosen over
other methods, owing to the ease of background screening and better signal-to-noise …

New methods for the spatially and temporally controlled delivery of chemical and/or
biochemical species using lowenergy visible light offers greater opportunities in …

The interaction of dyes and metallic nanostructures strongly affects the fluorescence and can
lead to significant fluorescence enhancement at plasmonic hot spots, but also to quenching …

In this paper, we report a novel approach using peptide CALNN and its derivative
CALNNGGRRRRRRRR (CALNNR8) to functionalize gold nanoparticles for intracellular …

Potential utilization of proteins for early detection and diagnosis of various diseases has
drawn considerable interest in the development of protein-based detection techniques …

Plasmon-enhanced fluorescence (PEF) is an emerging technology for sensitive detection. It
relies on the plasmonic effect of a noble metal nanostructure to dramatically enhance the …
