Resumen:
Nano-carriers are defined as those nanoparticles (NPs) capable of trapping bioactive components inside, transport and then release them in a controlled manner at the target site. NPs have the ability to interact with cells and tissues at the molecular level. It has been proposed that the encapsulation nanocarriers protect the bioactive components of unfavorable environmental conditions and also increase its solubility and bioavailability. We synthesized mesoporous silicate nanoparticles by the method described in Nandiyanto et al.1. It employs polystyrene as a template, and a surfactant and a hydrocarbon solvent as size particle controlling. Various synthesis conditions were tested and the structure characteristics such us NP diameter, pore sizes distribution were analyzed by TEM and SEM images. It could be observed that NPS ranging from 30 to 200 nm were obtained. Larger NPs also showed larger pore sizes of about 6 nm of diameter. NPs less than 100 nm of diameter have, on average, pores of 3 nm of diameter. The chemical composition was analyzed by EDS and mainly SO2 materials were observed.
