Encapsulation of polymer-coated GNPs into P6c SAPNs. TEM images of the encapsulation samples for (a) the polymer-coated GNPs with surface carboxylic acid functional groups (GNPs with -COOH), and (b) the polymer-coated GNPs with surface amine functional groups (GNPs with –NH2). (c) DLS profiles for volume distribution of hydrodynamic sizes of the encapsulation samples. The P6c protein concentration is 0.05 mg/ml for all samples.
