The book 'Surface-Modified Nanoparticles for Eco-remediation' explores how engineered nanoparticles - whose surfaces are deliberately modified or functionalized - can serve as powerful tools to clean polluted environments (water, soil, wastewater, and possibly air). Surface modification refers to altering the chemistry or coatings of nanoparticles so that they become more stable, selective, and effective in interacting with environmental contaminants. Core concepts and rationale: Compared to conventional remediation methods (like chemical precipitation, biological treatment, or filtration), nanoparticles possess a very high surface-to-volume ratio, making them extremely reactive and effective at capturing or degrading pollutants even at low concentration.
