Inhalable nanoparticles conjugated with hyaluronic acid, anti‐PD‐L1 antibody, RGD peptide, mannose, folic acid, LHRH peptide, and transferrin are developed to target tumor cells and show enhanced therapeutic efficiency in lung cancer [60, 61, 66, 69, 70, 71]. This evidence concerns the gene CD274 and neoplasm.
