Abstract
The free radical nitric oxide (NO) plays a key role in several biological processes in mammals, such as the control of vasodilation, the immunological responses, the inhibition of platelet adhesion, the cell communication, and the wound healing. In addition, NO is recognized as important molecule in several physiologic process in plants, including break seed dormancy, stimulate plant germination and greening, control iron homeostasis in plants, and improve plant tolerance to salinity, metal toxicity, temperature and drought stress. As a free radical, NO donors are administrated in several applications. Among them, S-nitrosothiols (RSNOs) are an important class of NO donors, since they spontaneously decompose releasing NO, and this decomposition can be triggered by light irradiation (visible region). Several papers in the literature reveal that the combination of nanotechnology and RSNOs is a promising strategy to allow the therapeutic uses of NO. In this context, the main goal of this project is the synthesis and characterization of RSNOs containing (i) biocompatible polymeric based nanoparticles (poly(lactic-co-glycolic acid), quitosan and polycaprolactone); (ii) ferromagnetic nanoparticles (Fe3O4@quitosana). The kinetics of thermal and photochemical NO release from the synthesized nanoparticles and the cytotoxicity and mechanisms of toxicity will be evaluated. Moreover, the NO-releasing nanomaterials will be applied on plants under abiotic stresses. The project hopes to contribute to the design of biocompatible NO-releasing nanomaterials for biomedical and agriculture applications. (AU)
