a Schematic structures of L- (left) and D-GSH-QDs (right). b High-resolution transmission electron microscopy images of D- and L-GSH-QDs. The circles indicate the spacings of the CdTe (220) or (111) lattices. c Chirality- and concentration-dependent cytotoxicities of the QDs. d L-GSH-QDs induce autophagy more effectively than D-GSH-QDs (40 nm).
