The present invention provides a method for improving the stability of nanomaterials. The flagellin FilC and porin OmpF from Lahenia aquatica and Escherichia coli are used to improve the stability of nanomaterials, and the nanomaterials can be selected from nano-selenium, nano-gold and nano-silver. Compared with other nanomaterial stabilizers (such as SDS, PEG, PVP, BSA, and Escherichia coli FilC and OmpF), FilC and OmpF from Lahenia aquatica are stable chemically synthesized nano-selenium not affected by strong acid, strong alkali and Under the influence of strong ion concentration, the stabilizing efficacy of FilC and OmpF of Lahenia aquatica was 10-100 times higher than that of PVP, BSA and Escherichia coli FilC and OmpF. Lahenia aquatica FliC and OmpF can also significantly increase the stability of nano-gold and nano-silver under the condition of strong ion concentration, and the effect is significantly better than that of E. coli FilC and OmpF. |
