Since the ET‐peptide‐conjugated RBCEVs performed better than α‐EGFR‐VHH‐conjugated RBCEVs in enhancing the specific uptake of the EVs, we further used ET‐peptide‐conjugated RBCEVs for drug delivery in the treatment of lung cancer shown below. The gene discussed is EGFR; the disease is lung carcinoma.
