Cellular uptake of MNPs by smooth muscle cell (SMC). All values are represented the mean ± standard deviation (SD) of three experiments, each performed in triplicate. Control columns mean that SMC was incubated with only DMEM.aSMC was incubated with DMEM containing the indicated concentration of DMSA-MNPs for 24 h.bSMC was incubated with DMEM containing 0.1 mg/mL DMSA-MNPs for the indicated incubation time, andcSMC was incubated with DMEM containing 0.1 mg/mL indicated MNPs for 24 h
