The NSs’ outer layer was coated with HA to improve biocompatibility and enable active targeting of tumor cells utilizing CD44+ upregulation on the cancer cells membranes.[107] The resulting Ti3C2Tx‐DOX exhibited notable drug loading capacity (up to 84.2%), remarkable biocompatibility, efficient pH‐responsiveness, and responsive drug release under NIR laser stimulation, as demonstrated by in vivo and in vitro experiments." Similar to this, large specific surface area SP‐modified Ti3C2 NSs (Ti3C2Tx‐SP) can also be stuffed with anticancer drugs (DOX) for effective tumor removal. This evidence concerns the gene CD44 and cancer.
