Polyglycerol coating: A breakthrough in safer nanoparticle environmental remediation

Engineered nanoparticles (NPs), commonly utilized in environmental remediation, can pose significant toxicity risks upon ingestion by organisms. Researchers have now devised a solution to this challenge by creating a hydrophilic coating, utilizing polyglycerol (PG) functionalization, for NPs. This coating effectively prevents NP aggregation inside organisms' bodies and facilitates easier passage, thereby reducing accumulation. Applicable to various NPs, the novel surface functionalization approach holds promise for addressing concerns about NP toxicity in environmental remediation.
