2. This molecule is water-soluble and can be encapsulated within the inner cavities of liposomes. IR820 is more stable at different temperatures and has longer tissue retention time and better biosecurity than ICG.
12 PTT can kill primary tumor cells but cannot eradicate metastatic tumor cells, whereas chemotherapy, as a systemic treatment, can kill primary and metastatic tumor cells.
13 Therefore, the combination of chemotherapy and PTT in the treatment of cancer has attracted considerable attention in basic research and clinical practice.
Over the past few decades, scholars have studied many nanodrug delivery carriers, including liposomes, polymeric micelles, polymer-drug conjugates, and dendritic macromolecular nucleic acid nanoparticles, among which liposomes and polymer-drug conjugates are the dominant nanoparticles in clinical applications.
