Inorganic nanoparticle oxide surfaces (MONP surfaces)

Inorganic nanoparticle oxide surfaces represent the reactive interface of metal oxide nanomaterials, such as titanium dioxide (TiO2), zinc oxide (ZnO), and iron oxides (Fe3O4), which are extensively utilized in nanomedicine and diagnostics (Source: NIH/NCBI, PMC5664196). These surfaces are characterized by high surface-to-volume ratios and specific chemical reactivities that allow for the adsorption of biomolecules, forming a 'protein corona' that dictates biological identity and cellular uptake (Source: Nature Nanotechnology, doi:10.1038/nnano.2012.115). While not traditional biological targets like receptors or enzymes, these surfaces act as functional platforms for drug delivery, imaging contrast enhancement, and therapeutic interventions through the generation of reactive oxygen species (ROS) or thermal energy (Source: PubMed, PMID: 29131305). In oncology, they are employed for targeted drug delivery and photodynamic therapy, while their intrinsic antimicrobial properties are leveraged against multi-drug resistant pathogens (Source: Frontiers in Pharmacology, doi:10.3389/fphar.2018.01151). However, their high surface energy can lead to unintended toxicological effects, including membrane disruption and chronic inflammation, necessitating careful surface engineering to ensure biocompatibility (Source: Particle and Fibre Toxicology, doi:10.1186/s12989-016-0151-4).

Inorganic nanoparticle oxide surfaces function primarily as platforms for drug delivery or as active agents that induce oxidative stress through the generation of reactive oxygen species (ROS). They can also facilitate thermal ablation (hyperthermia) or act as contrast agents in medical imaging by interacting with external magnetic or electromagnetic fields (Source: PubMed, PMID: 29131305).
