Nanoremediation

Definition

Nanoremediation is a cutting-edge technique that utilizes nanotechnology to remove or neutralize pollutants from soil, water, and air. This innovative approach involves the application of nanomaterials that can effectively degrade contaminants or enhance the natural processes of bioremediation, leading to cleaner environments. By targeting specific pollutants at the nanoscale, nanoremediation offers the potential for more efficient and cost-effective solutions to environmental cleanup challenges.
