Resistance in both can be overcome>
- pomegranate rind extract, which inhibits both flagellin and biofilm production,
or
- by covalently binding #AgNP to a composite material containing graphene sheets, which protects AgNP aggregation.

G- E.coli produces flagellin (basically to whip AgNPs to precipitate. (similarly as in our

G+ S.aureus form biofilm around AgNPs to incapacitate its antibacterial properties.
Bacterial resistance to silver nanoparticles and how to overcome it - Nature Nanotechnology
Gram-negative bacteria exposed to subinhibitory concentrations of silver nanoparticles can develop resistance to their antibiotic activity due to the production of flagellin, an adhesive protein of th...

Antibacterial resistance to silver nanoparticles is the same for both types of bacteria - aggregation of AgNP to form black precipitates.

However, the way in which Gram-positive and Gram-negative bacteria induce aggregation of silver nanoparticles is completely different.
