Abstract
Titanium dioxide (TiO2)-based nanostructures have wide applications in cosmetics, toothpastes, pharmaceuticals, coatings, papers, inks, plastics, food products, textiles, and many others. Recently, they have also been found to have huge potential as stem cells' differentiation agents as well as stimuli-responsive drug delivery systems in cancer therapy. In this review, we present some of the recent progress in the role of TiO2-based nanostructures toward the above-mentioned applications. We also present recent studies on the toxicity issues of these nanomaterials and the mechanisms behind the toxicity issues. We have reviewed the recent progress of TiO2-based nanostructures on their stem cells' differentiation potentials, their photo- and sono-dynamic capabilities, as stimuli-responsive drug delivery systems, and finally their toxicity issues with mechanistic understanding on the same. We believe that this review will help researchers be aware of the latest progress in the applications as well as few toxicity issues associated with TiO2-based nanostructures, which will help them design better nanomedicine for future applications.
期刊介绍：
Nanotoxicology invites contributions addressing research relating to the potential for human and environmental exposure, hazard and risk associated with the use and development of nano-structured materials. In this context, the term nano-structured materials has a broad definition, including ‘materials with at least one dimension in the nanometer size range’. These nanomaterials range from nanoparticles and nanomedicines, to nano-surfaces of larger materials and composite materials. The range of nanomaterials in use and under development is extremely diverse, so this journal includes a range of materials generated for purposeful delivery into the body (food, medicines, diagnostics and prosthetics), to consumer products (e.g. paints, cosmetics, electronics and clothing), and particles designed for environmental applications (e.g. remediation). It is the nano-size range if these materials which unifies them and defines the scope of Nanotoxicology .
While the term ‘toxicology’ indicates risk, the journal Nanotoxicology also aims to encompass studies that enhance safety during the production, use and disposal of nanomaterials. Well-controlled studies demonstrating a lack of exposure, hazard or risk associated with nanomaterials, or studies aiming to improve biocompatibility are welcomed and encouraged, as such studies will lead to an advancement of nanotechnology. Furthermore, many nanoparticles are developed with the intention to improve human health (e.g. antimicrobial agents), and again, such articles are encouraged. In order to promote quality, Nanotoxicology will prioritise publications that have demonstrated characterisation of the nanomaterials investigated.
