This paper reviews fundamentals of optical affinity biosensors based on plasmonic
nanostructures and discusses recent advances in the development of this technology …

In recent years, nanoplasmonic sensors have become widely used for the label-free
detection of biomolecules across medical, biotechnology, and environmental science …

Heavy metal pollution is one of the most serious environmental problems, which undermines
global sustainability. Many efforts have been made to develop portable sensors for …

The bright colours of noble metal particles have attracted considerable interest since
historical times, where they were used as decorative pigments in stained glass windows …

We developed a facile method for the synthesis of Gold nanoparticles (AuNPs) stabilized by
cationic 1-(3-(acetylthio) propyl) pyrazin-1-ium ligand denoted as APP. Gold nanoparticles …

Nanostructured, just-percolated gold films were prepared by evaporation on bare glass.
Annealing of the films at temperatures close to or higher than the softening temperature of …

This work appraises a facile method for detecting lead ions in an aqueous medium. For this
purpose, a d-shaped optical fiber is functionalized with gold nanoparticles with further …

Microfluidic and lab-on-a-chip systems have become increasingly important tools across
many research fields in recent years. As a result of their small size and precise flow control …

The mirror‐like near‐perfect reflective behavior of bulk noble metals becomes distinctively
different when they are separated into nanoparticles with dimensions much smaller …

This paper reports on the use of the Lorentz− Drude model to investigate the refractive index
sensitivity, S (change of nanometer per refractive index unit, in nm RIU− 1) of multilayered …
