Near-infrared fluorescent probe for hydrogen sulfide: high-fidelity ferroptosis evaluation in vivo during stroke

A H 2 S triggered and H 2 S releasing near-infrared fluorescent probe (HL-H2S) was developed. HL-H2S does not interfere with the progression of ferroptosis by consuming H 2 S, thus enabling high-fidelity in situ imaging of ferroptosis.
