Antimicrobial Activity of Noncovalent Graphene/Polymer Conjugates |
| 초록 |
Stable aqueous dispersions of reduced graphene are simply obtained by reducing GO solution in the presence of poly(2-vinyl pyrrolidone) (PVP) or chitosan. Prepared aqueous graphene solution are optically clear and stable for several months without any aggregation or precipitation. Both DLS and AFM analysis confirm that efficient binding of PVP or chitosan chains on reduced graphene plates. Hydrophobic interaction between reduced graphene plates and either PVP or chitosan chains might be responsible for this stabilization of above graphene/polymer conjugates in solution. Both graphene/polymer conjugates show excellent antimicrobial activity for Salmonella typhimurium TA98. |
