The extracellular pHe maps of PSMA‐expressing PC3‐PIP subcutaneous tumors confirmed the development of acidity in the interstitium, with regions reaching as low pHe values as 6.5 (Figure 6a); these pHe values were adequate to activate both the release and adhesion properties on the tumor‐responsive liposomes (Table 1).12, 16. Here, FOLH1 is linked to neoplasm.
