In another workgroup that dealt with ICG, Luo et al. (2019) established artificial cells by encapsulating Hb-ICG complexes into a lipid-polymer nanoparticle that permitted self-enrichment of oxygen within the cancer tissue, which further provide ROS generation during PDT, hence ensuing effective inhibition in tumor growth (Luo et al., 2016). Here, GSTM1 is linked to neoplasm.
