Silkworm Excrement Carbon Dot Nanomicelles

Augments PD-L1 Immunotherapy

Carbon dots derived from silkworm excrement are integrated into novel tumor-targeting nanomicelles, inducing immunogenic cell death via ferroptosis and photodynamic therapy, while downregulating PD-L1 to potentiate immune checkpoint blockade.
