White-light oblique-incidence diffuse reflectance spectroscopy for classification of in-vivo pigmented skin lesions [PDF]
SPIE Proceedings, 2007 A study of in-vivo classification of pigmented skin lesions using oblique-incidence diffuse reflectance spectroscopy is presented. Spatio-spectral data in the wavelength range from 455 to 765 nm are collected from 111 pigmented lesions including 10 histopathologically diagnosed as melanoma. The first 67 lesions are used for training the classifiers,

Macroscale multimodal imaging reveals ancient painting production technology and the vogue in Greco-Roman Egypt. [PDF]
, 2017 Macroscale multimodal chemical imaging combining hyperspectral diffuse reflectance (400-2500 nm), luminescence (400-1000 nm), and X-ray fluorescence (XRF, 2 to 25 keV) data, is uniquely equipped for noninvasive characterization of heterogeneous complex ...

The 1st International Electronic Conference on Biosensors, 2020 Carbendazim is a systemic, broad-spectrum benzimidazole-type fungicide effective against fungi that compromise the safety/quality of food products (fruits, vegetables, field crops, etc.). Though carbendazim constitutes a major environmental pollutant, hazardous for humans and animals and has been banned in most of European Union and USA, many countries

Autofluorescence and diffuse reflectance spectroscopic analysis of oral premalignancy and malignancy
Journal of Indian Academy of Oral Medicine and Radiology, 2009 Early detection of squamous cell carcinoma in the oral cavity can improve survival. It is often difficult to distinguish neoplastic and premalignant disorders with standard white light illumination.

Label-free kinetic study of biomolecular interactions by white light reflectance spectroscopy
Micro & Nano Letters, 2006 Binding of biomolecules in real-time is studied by white light reflectance spectroscopy (WLRS). The experimental apparatus consists of a WLRS setup and a microfluidic channel for the supply of the biomolecules solutions placed above the sample on which the biomolecular interactions take place.
