Spectroscopic Characteristics of Xeloda Chemodrug. [PDF]

open access: yesJ Lasers Med Sci, 2021
Introduction: Spectroscopic properties of Xeloda chemodrug have been studied over varying concentrations ranging between 0.001 and 10 mg/mL, using laser-induced fluorescence (LIF) spectroscopy. The alternative photoluminescence (PL) and near infrared (NIR) measurements are carried out to authenticate the obtained results by the LIF method. Methods: The

Spectroscopic Characteristics of Human Melanin In Vivo

open access: yesJournal of Investigative Dermatology, 1985
In this paper we present the absorption characteristics of human melanin in the visible range of wavelengths and specifically in the range 620-720 nm. The spectroscopy of melanin is studied by measuring remittance spectra of normal skin and vitiligo-involved skin of volunteers-patients. It is assumed that the spectral differences between adjacent areas
