GSTM1 and Stroke: Based on the pathological microenvironment characteristic of stroke, Liu [81] et al. introduced PDA to noncovalently engage Hb and methoxatin (M) to form PMH, whose surface-coated ROS-sensitive linker (thioketal, termed TK linker) connects to a specific fibrin-binding peptide (CREKA, termed C-peptide), and they developed a bioinspired nanoerythrocyte (C-peptide-PRG-TK linker @PDA-Methoxatin Hb, referred to as CPTK@PMH).
