Fig. 1From: Advanced platelet-rich fibrin plus gold nanoparticles enhanced the osteogenic capacity of human mesenchymal stem cellsTEM analysis AuNPs. AuNPs are spherical with a mean size of 53 ± 2 nm (a) DLS analysis indicated the distribution of AuNP size within the original suspension comparable to TEM imaging (b). DLS showed − 19.6 mV zeta potential for synthesized AuNPs (c)Back to article page
