Theranostic nanoparticles based in superparamagnetic iron oxide for skin cancer therapy by magnetic hyperthermia


The development of multifunctional devices, also called nanoparticles teranósticas (NPT - a strategy that integrates therapy and diagnosis in one step) has been showing strong growth in recent decades. However, it is still evolving and many barriers must be overcome before they can be used clinically. This project is proposed to develop theranostic nanoparticles based in magnetic nanoparticles containing targetable molecules for folate groups on its surface in order to provide skin cancer treatment by magnetic hyperthermia. The multifunctional devices will be evaluated by in vitro and in vivo assays in order to potentialize the application of this system in the nanobiomedical areas. The first part of this project to consiste in the investigation of the magnetite nanoparticles synthesis via modifications in both processes: thermal decomposition and precipitation from aqueous solution containing iron chloride partly reduced. The preparation of teranostic nanoparticles will be performed by surface functionalization with folic acid. In addition, colloidal stability and magnetic hyperthermia studies in order to optimize the system stability for applying multifunctional devices will be realized. In a second step, the synthesized TNP will be tested to determine cell viability by using different cell lines with the aim of analyzing both cytotoxicity and the TNP internalization into the cells. Permeation tests and teranostic nanoparticles dissolution by using a membrane of natural origin, as well as the layers permeation analysis into the the membrane after the TNP application will also realized. Magnetic hyperthermia assays will be performed in mice with chemically induced skin cancer in order the goal of evaluating the effectiveness of treatment via magnetic hyperthermia therapy. Therefore, the theme of this project falls in an area of strategic technology worldwide and thus it is believed that the innovative and impressive results may be obtained. (AU)
