Abstract
A protein product capable of immobilizing a target and being cleared as required includes a protein (lysozyme, bovine serum albumin (BSA), whey albumin, insulin, α-lactalbumin, fibrinogen, ribonuclease A, cytochrome c, α-amylase, horseradish peroxidase (HRP), pepsin, myoglobin, collagen, keratin, or the like), a protein modifier (a strong oxidizing agent or a strong reducing agent), and a matter to be immobilized (a coating, a pesticide, a chemical fertilizer, a cosmetic, a medical drug, or the like). A protein film can be generated through the phase transition of the protein to immobilize the matter to be immobilized on a target surface, thereby improving the utilization rate of the matter to be immobilized and reducing the resource waste and environmental pollution caused by the loss of the matter to be immobilized. In addition, after the protein film is decomposed, the matter to be immobilized will also be effectively cleared.
