The Biophotonics Laboratory at the Physics Department of the Federal University of Minas Gerais (UFMG), Brazil! The Biophotonics Lab Group is directed by Professors Ana Maria de Paula and Leandro Malard Moreira.
Our research activities and interests encompass three major areas: (1) preparation and characterization of semiconductor quantum dots and metal nanoparticles for biological systems applications; (2) study of nonlinear optical effects in biological tissues and nanostructured materials; and (3) investigation of ultrafast dynamics of photoexcited carries in two-dimensional materials.
Instrumentation at the Biophotonics Lab includes pulsed Ti:sapphire laser oscillator (Chameleon, from Coherent); visible and infrared spectrometer (Andor, Shamrock); modified confocal laser-scanning microscope (Olympus FV300); setup for pump-probe experiments using optical and infrared wavelengths; among other things.
