Characterizations of the MH-PLGA-IR780 NPs. A, B TEM images of PLGA NPs and MH-PLGA NPs. (scale bar: 100 nm). C SDS-PAGE protein analysis results. D Western blot analysis of membrane-specific protein markers. E, F Size distributions of the PLGA-IR780 NPs and MH-PLGA-IR780 NPs were measured by DLS. G, H Zeta potential (n = 3) and digital images of different NPs (PLGA NPs, PLGA-IR780 NPs, and MH-PLGA-IR780 NPs). I Absorbance spectra of IR780 in a concentration-dependent manner as recorded by UV–vis spectroscopy. J UV–vis spectra of single IR780, PLGA NPs, PLGA-IR780 NPs, and MH-PLGA-IR780 NPs
