Nanoparticles (NPs) are increasingly used, but their environmental fate and nanotoxicity are poorly understood. This review focuses on titanium dioxide (TiO2) NPs, examining their molecular toxicology and future research directions.
Area of Science:
- Nanotechnology
- Environmental Science
- Toxicology
Background:
- Nanoparticles (NPs) show significant progress in nanotechnology and biomedical fields.
- Industrial demand for NPs has surged, yet their environmental fate remains largely unknown.
- Nanobiosafety, specifically nanotoxicity, is a critical concern requiring thorough investigation.
Purpose of the Study:
- To review the chemical and biological concerns associated with nanoparticles.
- To emphasize the toxicological profile of titanium dioxide (TiO2) NPs at the molecular level.
- To discuss challenges and future prospects in nanotoxicology.
Main Methods:
- Literature review of chemical and biological concerns of NPs.
- Focus on in vitro and in vivo toxicological data for TiO2 NPs.
- Analysis of existing research to identify knowledge gaps and future directions.
Main Results:
- TiO2 NPs present both chemical and biological risks.
- Molecular-level toxicological data for TiO2 NPs from in vitro and in vivo studies are presented.
- Current understanding of NP environmental fate and nanotoxicity is limited.
Conclusions:
- Further research is crucial to understand the environmental impact and biosafety of NPs.
- Detailed toxicological profiling of NPs like TiO2 is essential.
- Addressing nanotoxicity challenges will guide future research and safe application of nanotechnology.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
