The aggregation of nanoparticles has been shown to significantly reduce the activity nanomaterials, resulting in inferior performance. As an alternative use traditional capping agents, stabilization unstable with water-dispersible and biocompatible carriers is a promising strategy. A bioinspired coating strategy was developed hybrid displayed excellent colloidal stability that improved antibacterial when silver (AgNPs) were used as model. Cellulose nanocrystals (CNCs) first modified dopamine, followed by situ generation anchoring AgNPs on surface CNCs through reduction ions polydopamine coated CNCs. results indicated dispersion enhanced CNC, which turn resulted more than fourfold increase based studies using Escherichia coli Bacillus subtilis.
