Spectroscopic Characteristics of Xeloda Chemodrug. [PDF]
J 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
