Neurotrophins,and growth factors in general,are proteins which exert many actions in central nervous system *** promote the survival and neuronal function of neurons and exert neuroprotective effects in pathological models of neurodegenerative *** humans several clinical trials based on the use of these proteins have been carried out. Among them, it is worth to mention gene ther- apy especially in Parkinson＇s disease （PD）（Kordower and Bjorklund, 2013）, and a series of experiments using vectors capable of carrying neurotrophins in the selected target re- gion where they can exert their beneficial action （Ghosh et al., 2014）.

A major issue in the development of Lead halide perovskites is the assessment of the crystal structure of the samples,due to their typically limited time-stability,and the understanding of the role of external factors that can induce a crystal phase transformation(such as humidity,intense light flux,temperature,etc.).In this perspective,it is of utmost importance to have at disposal a fast and reliable experimental tool able to give an immediate indication of the polymorph of the sample with the possibility to integrate in-situ measurements for constant *** this paper we propose Raman spectroscopy as the ideal technique to solve this *** vibrational analysis of CsPbI3 in the a-phase and 5-phase and of the Cs4PbI6 secondary phase is reported and all the vibrational modes are assigned by comparing experimental spectra of the phases to Raman modes calculated within the DFT ***,the mechanism of laser induced phase degradation was studied using in-situ Raman measurements providing new insights on the secondary phase generated during the process.
