Figure 6From: A multifunctional ribonuclease A-conjugated carbon dot cluster nanosystem for synchronous cancer imaging and therapyCytotoxicity assay results. (a) MTT assay determined cytotoxicity profile of RNase A, C-dots, and RNase A@C-dots after 24 h incubation with MGC-803 cells at varied concentrations (sample size N = 3). (b) Dynamic monitoring cytotoxic response of MGC803 cells to RNase A, C-dots, and RNase A@C-dots.Back to article page
