Near-field optical microscopy and spectroscopy provide high-resolution imaging below the diffraction limit, crucial in physics, chemistry, biology for studying molecules, nanoparticles, viruses. These techniques use a sharp metallic tip of an atomic force microscope (AFM) to enhance incoming scattered light by excited near-fields at apex, leading high sensitivity spatial resolution few nanometers. However, this restricts near-field orientation out-of-plane polarization, limiting polarization...
Optimizing the antibacterial properties of nanocomposites is a fundamental challenge for many biomedical applications. Here, we study how may optimize activity narrow-sized anisotropically flat silver nanoprisms (S-NPs) on graphene oxide (GO) against Escherichia coli. To do so, transformed nanoparticles (AgNPs) into S-NPs and anchored them to GO via facile low-cost photochemical reduction method by varying irradiation wavelength during synthesis process in visible range (440 650 nm white...
Triangular silver nanoplates (T‐SNPs) are synthesized via a facile, low‐cost photochemical process. It is proved that both the pH and concentration of trisodium citrate (TSC) key factors to describe mechanism for growth modulation extinction band along formation T‐SNPs. A precise photoreduction T‐SNPs proposed confirmed by X‐ray photoelectron spectroscopy (XPS) considering face block theory localized surface plasmon resonance (LSPR) in revealing optimal conditions their be at neutral 7,...
