In Vivo PDT Experiment

Animals were used in PDT experiments when the tumor size reached ∼150 mm³. Day 0, intratumoral injection; day 1, for the treatment group, light treatment was performed on the tumor site. The mice continued to be fed for 14 days. See MCF-7 Xenograft Model and In Vivo PDT Experiment in Transparent Methods for experimental details.
