| Abstract | |
This work of doctorate thesis bases on a scientific development thoroughly multidiscipline combining protocols, techniques and experimental assays of the pharmaceutical technology, nanotechnology, tissue engineering and photobiology. The work was accomplished in three subsequent stages. Firstly were carried out studies and characterization of a drug delivery system with nanotechnology, which was evaluated thoroughly starting from physical-chemical tests and assays of cytotoxicity in human fibroblast culture. In the sequence were carried photobiological studies combining the application of low-intensity laser and nanosized photosensitizers with tissue models, for evaluation of the biological photostimulation. In mimetic conditions it was developed an in vitro three-dimensional human skin model, as tool to evaluate the photobiological response after the induction of the photodynamic processes and also as alternative for in vitro assays of drug permeation/retention. Results were promising, aiding in the understanding of interaction of extracellular matrix with photodynamic processes. Therefore, the work was based in combination of techniques with application in dermatology, pharmaceutical process, cosmetics and correlate areas. (AU) | |
