The characterizations of nanoparticles. BET nitrogen adsorption /desorption isotherms (a), and BJH pore size distribution of MSN, MSN-COOH and RDMSNs. After carboxyl grafting and cargo loading, the pore volume and pore diameter of nanoparticles decreased, indicating that the nanopores were blocked by the incorporated DOX and rituximab molecules (b)
