The great promise of photodynamic therapy (PDT) has thrusted the rapid progress of
developing highly effective photosensitizers (PS) in killing cancerous cells and bacteria. To …

The nature of “hot spots” in surface-enhanced Raman scattering (SERS) and the novel
fabrication of Ag thin films for efficient SERS measurements are the main focus of this …

Plasmonic systems based on metal nanoparticles on a metal film have generated great
interest for surface-enhanced Raman spectroscopy (SERS) chemical sensors. In this study …

Wide applications of surface plasmon resonance rely on the in-depth understanding of the
near-field distribution over a metallic nanostructure. However, precisely locating the …

The progress of surface-enhanced Raman scattering (SERS) microscopy and spectroscopy
on individual nanostructured materials has been reviewed in this feature article. After a brief …

Surface-enhanced Raman spectroscopy is performed on pairs of gold nanoparticles, for
which the nanoparticles in each pair have different shapes. The dimers therefore exhibit two …

The controlled surface functionalisation of polystyrene beads (200 nm) with a lipoic acid
derivative is used to assemble composites with between 4 to 20% loadings of citrate …

When semiconducting nanostructures are combined with noble metals, the surface
plasmons of the noble metals, in addition to the charge transfer interactions between the …

We demonstrate an active microfluidic platform that integrates dielectrophoresis for the
control of silver nanoparticles spacing, as they flow in a liquid channel. By careful control of …

Abstract Three-dimensional (3D) surface enhanced Raman scattering (SERS) substrates
were produced by magnetic force assisting self-assembled nanoparticles in arrayed holes …
