Fluorescence spectrum of Ln-ZIFrPMo-EGCG and B) fluorescence intensity in the red and NIR spectral region (left) and power density of 808 nm laser (right) under different thickness of tissue. C)IRED/INIRfluorescence ratio, D) E.T. change (B), and E) amount of released EGCG of Ln-ZIFrPMo-EGCG under different thickness of tissue. The E.T. and drug release amount were measured as a function of laser power density and irradiation time, which was considered as two parameters in the irradiation prescription. E.T. and EGCG amount in the effective range was outlined by a dark red dotted line. Data represented as mean SD (n= 3).
