| titleOfInvention | PH-sensitive fibroin nanofiber, and dispersion liquid, preparation method and application thereof |
| abstract | The invention belongs to the technical field of preparation of fibroin nanofibers, and relates to a pH-sensitive fibroin nanofiber, and a dispersion liquid, a preparation method and an application thereof. The preparation method comprises the following steps: adding silk into the acidic solution to obtain a mixed solution; heating the mixed solution at constant temperature, and stirring to obtain a solid suspension; and separating the water-insoluble substances in the solid suspension, and washing the water-insoluble substances to be neutral to obtain the pH-sensitive fibroin nanofiber. The fibroin nanofiber is a water-insoluble crystalline structure, does not generate conformational transition or gelation, can be stably dispersed in an aqueous solution, and has good pH responsiveness and biocompatibility. The preparation method adopted by the invention has simple process, is non-toxic and harmless, improves the yield of the fibroin nanofiber, and provides a new idea and a new method for realizing the efficient utilization of fibroin-based biomass resources. |
