a TEM image of fabricated PoGNP. Inlet image shows nanobundles on the surface of PoGNP. b sGNP, c AgNP, d Mean of cumulative size of nanoparticles determined by DLS analysis. Zeta potential of each nanoparticle was also obtained. The unlabeled scale bars represent 200 nm. PoGNP, porous gold nanoparticle; sGNP, spherical gold nanoparticle; AgNP, silver nanoparticle
