However, recently surface functionalization of the outer oil portion of the emulsions are being studied to improve the drug targeting to the specific tumor.79 Active targeting methods for nanoemulsions also use peptides such as RGD peptide and transferrin, small molecules such as biotin and folate, or certain antibodies specific to tumor surface antigens.80 Novel targets such as lysophosphatidic acid receptor is also being studied to improve the drug targeting to specific tumors.79 Here, TF is linked to neoplasm.
