The present invention provides a nano/micro bubble system for drug delivery comprising a gas core, a plurality of surfactants and an active ingredient. The surfactants surround the gas core and form a double-layer structure having an inner layer and outer layer. The active ingredient is embedded in a gap formed between the inner layer and the outer layer of the double-layer structure and comprises a nucleic acid, a peptide or a protein.
