Nonspecific targeting and low efficiency are challenges to face in tumor treatment. By utilizing the unique microenvironment (TME) of acidic condition overexpressed H2O2, nanozyme with peroxidase (POD)-like activity for decomposing H2O2 into extremely toxic hydroxyl radicals (•OH) destroy cancer cells situ is promisingly addressed tumor-specific However, catalytic therapeutic most current POD-like nanozymes usually counteracted by weak acidity (pH 6.0–6.7) insufficient (∼50–100 μM) TME. Herein, we report a mercaptosuccinic acid-derived carbon quantum dot (MA-CQD) nanozyme, which highly biocompatible possesses superior (Km = 0.58 mM) under TME, therefore efficiently convert trace amounts endogenous treatment, while posing minimal nonspecific damage normal tissues neutral 7.4). MA-CQDs confirmed cause an intensive caspase-1/gasdermin D-mediated cell pyroptosis through produced reactive oxygen species, providing effective way therapy. Our nanocatalyst demonstrates desirable suppression rate. This work offers prospective mode therapy inspires development cancer-specific pyroptotic nanomedicine.

Triphenylphosphine functionalized carbon dots (TPP-CDs) showcase robust mitochondria targeting capacity owing to their positive electrical properties. However, TPP-CDs typically involve complicated synthesis steps and time-consuming postmodification procedures. Especially, the one-step target-oriented of regulation TPP linkage modes remain challenges. Herein, we propose a free-radical-initiated random copolymerization in combination with hydrothermal carbonation regulate backbone for triphenylphosphine (TPPcopoly-CDs). The mechanism reactions is directional, straightforward, controllable. content IC50 hydroxyl radicals scavenging ability TPPcopoly-CDs are 53 wt % 0.52 mg/mL, respectively. serves as charge control agent elevate negatively charged CDs by 20 mV. negative can target mitochondria, corresponding moiety plays crucial role mitochondria. This discovery provides new perspective on controlled synthesis, modes, mitochondrial design TPP-CDs.
