2.6.1 Methods to Overcome the Nanotoxicity
Because of the severity of nanotoxicity, there is an immediate requirement of
advance strategies to minimize the toxic effects of nanosubstances. The following
are a few ways to avoid and regulate the nano-ecotoxicity:
• By coating the NPs with biocompatible complexes. For example, ZnO NPs have
exceptional antimicrobial potential but their utilization as food additives is
restricted as they are toxic in nature. Considering this, Chia and Leong (2016)
studied the coating of ZnO NPs with Si to lessen the toxicity. It was confirmed
that the Si layer did not change the antimicrobial potential of the ZnO NPs against
S. aureus and E. coli. Additionally, Si coating averts the dissociation of ZnO NPs
into zinc ions (Chia and Leong 2016).
• By coating with natural substances or with complexes that mimic the properties of
the natural substances to overcome the toxicity.
