The controlled release of drugs/nanoparticles can be efficient if a suitable encapsulation procedure is developed, which requires biocompatible materials to hold and release the drug/nanoparticles. Natural rubber latex (NRL) has been proven excellent for its biocompatibility and ability to stimulate angiogenesis. In this study, a natural rubber latex (NRL) membrane will be used to deliver drugs and nanoparticles. For this purpose . Metronidazole (MET) is a nitroimidazole anti-infective medication used mainly in the treatment of infections caused by susceptible organisms, particularly anaerobic bacteria and protozoa. Gold nanoparticles have been extensively studied over the last decade to treatment of cancer. The solutions of latex and drugs/nanoparticles will be polymerized at different temperatures, in order to control the membrane morphology. The number, size and distribution of pores in NRL membranes vary depending on polymerization temperature, as well as its overall morphology. The rate release of drugs/nanoparticles will be controlled varying the polymerization temperature of the latex matrix. The drugs/nanoparticles released into the solution will be monitored by measuring the UV-VIS spectrophotometer. These membranes will be characterized by Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Atomic Force Microscopy (AFM), Fourier transform infrared (FTIR) spectroscopy and mechanical resistance tests. The results will be analyzed under the perspective of understanding the interaction of drug/ nanoparticles in natural latex membranes.
