In this study, Indocyanine green (ICG), a photosensitizer and Monophosphoryl lipid A (MPLA), a Toll-like receptor 4 agonist, were encapsulated into the core of PEG-PLGA nanocarrier, and the surface was further modified with tumor-targeting peptide TMTP1. The gene discussed is TLR4; the disease is neoplasm.
