Metal-Enhanced Fluorescence from Nanoparticulate Zinc Films [PDF]

open access: yesThe Journal of Physical Chemistry C, 2008
A detailed study of metal-enhanced fluorescence (MEF) from fluorophores in the blue-to-red spectral region placed in close proximity to thermally evaporated zinc nanostructured films is reported. The zinc nanostructured films were deposited onto glass microscope slides as individual particles and were 1?10 nm in height and 20?100 nm in width, as ...

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Metal-Enhanced Fluorescence from Chromium Nanodeposits

open access: yes, 2016
Over the last several years, our laboratory has described in detail the favorable effects of fluorophores in close proximity to metallic nanoparticles. Metal nanoparticles comprised of gold, silver, copper, and zinc show enhanced fluorescence intensities

Metal Enhanced fluorescence emission and Quenching protection effect with a host-guest Nanophotonic-supramolecular structure [PDF]

open access: yes, 2018
The functionalization of the nanoparticle's (NP) surface is one method for tuning their overall properties to fit targeted applications. We developed a nanosensor based on the specific supramolecular interactions between β-cyclodextrin (βCD) nanocavities

Distance measurement between metal tips via plasmon-enhanced NV fluorescence

open access: yesNew Journal of Physics
High-precision displacement sensing serves as a cornerstone for measuring numerous physical quantities. Through plasmon-enhanced fluorescence, we propose a nitrogen-vacancy-based highly sensitive and microwave-free distance measurement scheme for metal ...

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.
