Spectroscopy Lab

Our spectroscopy laboratory is equipped with the most advanced technology for measuring absorption spectra of samples in solution, including a new nanospectrophotomer that measures only 0.3 µL of sample and three regular dual beam UV-Vis spectrophotometers, or in solid state using diffuse reflectance. In addition to these, two fluorometers, both with temperature control systems, are available in the same lab, one of them being equipped with a 980 nm laser diode for measuring the luminescence of Lanthanide upconversion particles. We also count with a well plate reader system that allows us to measure fluorescence, absorbance, or luminescence of up to 386 samples simultaneously. A circular/linear spectropolarimeter is also available in this lab, useful to explore the effect of nanoparticles on the conformation of biomacromolecules.

Additionally, the lab is equipped with the following pieces of equipment: an oxygen free glove box (commonly used to prepare oxygen sensitive nanoparticles like CuNP), an oxygen uptake transducer: a valuable tool that now is being used to explore the catalytic mechanism of AuNP supported on TiO2 in peroxide mediated reactions, and an Electron Paramagnetic Resonance system (with X-rays band).
