Ultrafast transient absorption spectroscopy

High precision thermochemistry studies of transient species. Quantum yields of fast photoinduced processes. Detection of fast structural volume changes in molecules and macromolecules.

Singlet oxygen detection and quantification.

i) fluorescência em estado estacionário ii) fluorescência resolvida no tempo

Based on acoustic detection of optical absorption from endogenous chromophores (e.g. hemoglobin) or exogenous contrast agents (organic dyes or nanoparticles), it is an imaging modality with great potential for preclinical research and clinical practice.

i) viabilidade celular; ii) fototoxicidade; iii) "uptake"; e iv) mecanismo de morte celular

i) estudos de fotoestabilidade incluindo avalição de fotocatalisadores, etc; ii) estudos espectroscópicos UV-Vis-NIR; iii) estudos fotofísicos; iv) estudos teóricos.
