Precise separation of small organic molecules and electrolyte salts is critical for various industrial processes, necessitating advanced membranes with uniform pores. Proteins, as one typical nature polymer having the exactly same structure and molecular weight, offer a promising material for making such membranes. Here, hemoglobin (BHb) and lysozyme (Lyz) are utilized to fabricate precise nanofiltration membranes through amyloid-like co-assembly, triggered by Tris(2-carboxyethyl) phosphine.
