[70]Fullerene was dissolved in water by the complexation with β‐1,3‐glucan using a mechanochemical high‐speed vibration milling apparatus. The photodynamic activity of β‐1,3 glucan‐complexed C70 was highly dependent on the expression level of dectin‐1 on the cell surfaces of macrophages. The photodynamic activity increased as a result of a synergistic effect between β‐1,3‐glucan‐complexed 1’‐acetoxychavicol acetate and the C70 complex.This work was supported by JSPS KAKENHI Grant‐in‐Aid for Scientific Research (B) (Grant No. JP16H04133), Grant‐in‐Aid for Scientific Research (C) (Grant No. 26350528) and Grant‐in‐Aid for Challenging Exploratory Research (Grant No. JP16K13982)
