Nonscanning large-area Raman imaging for ex vivo/in vivo skin cancer discrimination
Imaging Raman spectroscopy can be used to identify cancerous tissue. Traditionally, a step-by-step scanning of the sample is applied to generate a Raman image, which, however, is too slow for routine examination of patients. By transferring the technique

High-Resolution Near-Field Raman Microscopy of Single-Walled Carbon Nanotubes [PDF]
We present near-field Raman spectroscopy and imaging of single isolated single-walled carbon nanotubes with a spatial resolution of ≈25 nm. The near-field origin of the image contrast is confirmed by the measured dependence of the Raman scattering ...

Modulated Raman Spectroscopy for Enhanced Cancer Diagnosis at the Cellular Level
Raman spectroscopy is emerging as a promising and novel biophotonics tool for non-invasive, real-time diagnosis of tissue and cell abnormalities. However, the presence of a strong fluorescence background is a key issue that can detract from the use of ...

Isomorphic Substitution in Vanadinite [Pb5(VO4)3C1] - Raman Spectroscopic Study [PDF]
The Raman and infrared spectroscopy of three vanadinite [Pb5(VO4)Cl] specimens from three localities has been studied. Single crystal Raman spectra were obtained and the spectra were found to be both orientation and temperature dependent.

Photoinduced Inhibition of Neutrophil Extracellular Traps Formation by Dichromatic Light Irradiation
Neutrophils are the first line of defense of the human immune system against pathogens. Photobiomodulation, mediated by mitochondrial photoacceptors such as cytochrome c oxidase, has emerged as a method to modulate neutrophil function through targeted ...

FAST CARS: Engineering a Laser Spectroscopic Technique for Rapid Identification of Bacterial Spores [PDF]
Airborne contaminants, e.g., bacterial spores, are usually analyzed by time consuming microscopic, chemical and biological assays. Current research into real time laser spectroscopic detectors of such contaminants is based on e.g.

Rapid identification of pathogenic bacteria using Raman spectroscopy and deep learning [PDF]
Raman optical spectroscopy promises label-free bacterial detection, identification, and antibiotic susceptibility testing in a single step. However, achieving clinically relevant speeds and accuracies remains challenging due to weak Raman signal from ...

An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Synthesis and Characterization of Coated Gold Nanoparticles with Embedded SERS Tags [PDF]
Gold nanoparticles were prepared with the potential to operate as drug delivery vehicles. Surface-enhanced Raman spectroscopy (SERS) is of particular importance as an optical bioimaging technique due to its ability to allow deep and high-resolution ...
