Halloysite Nanotubes and Applications: A Review

Abstract

Various successful results of nanotechnology like carbon nanotubes, nanofluids, nanoparticles, nano emulsions, nano capsules, etc are not considered to be safe for humans as well as for environment because of their toxicology potencies. Halloysite nanotubes are naturally occurring eco-friendly nanotubes with low cost that are harmless to human. Halloysite Nanotubes (HNTs) are unique and versatile nanomaterials composed of double layered aluminosilicate minerals with a predominantly hollow tubular structure in submicron range. They are nontoxic in nature, have tuneable release rates and fast adsorption rates. These nanotubes have got wide range of applications in anticancer therapy, sustained delivery for certain agents, act as template or nanoreactor for biocatalyst, have found use in personal care and cosmetics and even used as environment protective.
