TOTALLY-MESOPOROUS ZIRCONIA NANOPARTICLES, USE AND METHOD FOR PRODUCING THEREOF

摘要

The present invention relates to novel totally-mesoporous zirconium oxide nanoparticles as well as a sol-gel synthesis process thereof which include an innovative nanoparticles purification step. Said nanoparticles are characterized by a totally-mesoporous structure i.e. a distribution of pores within the so-called the mesoporous range uniformly distributed throughout the entire nanoparticle volume. Furthermore, said nanoparticles are non-cytotoxic and present a high surface area, which make particularly suitable in both biomedical and industrial applications (e.g. drug delivery, heavy metals ion sequestration). The manufacturing method is simple and advantageously allows for high control over the shape and diameter of the nanoparticles as well as over the nanoparticles pores.
