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

Advanced 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.

Distance measurement between metal tips via plasmon-enhanced NV fluorescence

New 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 ...

Metal-Enhanced Fluorescence-Based RNA Sensing

Journal of the American Chemical Society, 2006
In this communication, we present the proof-of-principle of a new RNA sensing technique, based on metal-enhanced fluorescence, which may improve the potential of solid substrate-based RNA capture assays. In this regard, the detection of RNA is accomplished by annealing a target RNA tagged with a fluorophore to a DNA anchor probe in a single step on a ...

Spectral Distortions in Metal-Enhanced Fluorescence [PDF]

Biophysical Journal, 2015
In recent years our laboratory and others have demonstrated many examples and concepts in Metal-Enhanced Fluorescence1 (MEF), a surface plasmon phenomenon, which amplifies both fluorescence and luminescence signatures in the near-field, i.e. less than one wavelength of light away from a metallic object1.

Metal-Enhanced Fluorescence (MEF): Physical characterization of Silver-island films and exploring sample geometries

, 2009
In this study we have analyzed metal-enhanced fluorescence (MEF) effects from different density Silver-island films (SiFs) and the effects of sample geometry on the observed enhancement of fluorescence (EF).
