摘要：

Carbon quantum dots (CQDs) from heat-treated foods show toxicity, but the mechanisms of toxicity and removal of CQDs have not been elucidated. In this study, CQDs were purified from roasted coffee beans through a process of concentration, dialysis and lyophilization. The physical properties of CQDs, the degree and mechanism of toxicity and the removal method were studied. Our results showed that the size of CQDs roasted for 5 min, 10 min and 20 min were about 5.69 & PLUSMN; 1.10 nm, 2.44 & PLUSMN; 1.08 nm and 1.58 & PLUSMN; 0.48 nm, respectively. The rate of apoptosis increased with increasing...
