Abstract
The early development of nanotechnology has spurred major interest on the toxicity of nanoparticles (NPs) due to their ability to penetrate the biological barriers such as the BBB. This review aims at addressing how silver (AgNPs), titanium dioxide (TiO2NPs), zinc oxide (ZnONPs), iron oxide (Fe3O4NPs), carbon NPs, Copper (Cu-NPs), silicon oxide (SiO2 NPs) nanoparticles and quantum dots cause neurotoxicity. Some of the major signaling that occur are the signaling related to oxidative stress, neuroinflammation, mitochondrial dysfunction and cell equilibrium, hence results in neuronal damage and neurodegeneration. It is critical to describe that there are multiple ways by how NPs may be toxic based on their size and surface, dosage, and the recipient's age and health condition. A review on in vitro and in vivo analysis provides information about the toxic potentials of NPs and preventive measures including modification of NP surface and antioxidant treatment. The results underline the necessity of comprehensive safety assessments to allow the further utilization of nanoparticles across the economy.
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.
