A SpyCatcher peptide-modified carrier, a protein immobilizing carrier, and a protein immobilizing method. The method comprises: linking a SpyCatcher peptide to a carrier so as to obtain a SpyCatcher peptide-modified carrier; and then based on a SpyCatcher-SpyTag reaction, immobilizing a target protein containing SpyTag to the SpyCatcher-modified carrier. A protein immobilization process in which the method is used is fast, a condition is mild, no extra chemical reagent is needed, the immobilization efficiency and an activity recovery rate are high, and the homogeneity is good.

The preparation method of a starch-based double-loaded functional nanoparticle includes: performing restrictive hydrolysis treatment on egg high-density lipoprotein using proteases to obtain the polypeptide; performing self-assembling on a mixed system containing the polypeptide and quercetin under the alkaline condition to form a micelle nanoparticle; performing covalent grafting reaction on a mixed system containing the micelle nanoparticle and anthocyanin under the alkaline condition to form a graft; and electrostatically compounding carboxymethyl dextrin with the graft to obtain the starch-based double-loaded functional nanoparticle. In the preparation method, raw materials derived from natural sources are used, and the self-assembled colloid nanoparticle with good properties can be obtained by adjusting the pH without any organic reagents. The obtained product has a nanoparticle size, has high antioxidant activity and stability against environmental stress, and can be widely applied to the fields of delivery of nutrients, stabilization of biologically active substances and the like.

Method of removing or adsorbing a target substance or material, for example a metal, non-metal toxin, dye, or small molecule drug), from solution by functionalizing a substrate with a peptide configured to selectively bind to the target substance or material and to bind to the substrate. Methods herein are useful for example for biomining applications. More specifically, the method employs metal-binding peptides to remove metals from solution, particularly aqueous solution. More specifically, the substrate is fungal mycelium. Fusion peptides and/or proteins containing metal-binding domain sequence and optionally containing substrate-binding domain sequence are provided. Fusion peptides/proteins containing a metal-binding domain and a chitin-binding domain are provided. Also provided are nucleic acids encoding fusion peptides and/or proteins containing metal-binding domain sequence and those further containing a substrate-binding domain, for example a carbohydrate-binding domain, and more specifically a chitin-binding domain.
