Abstract: The present application discloses a recombinant humanized type III collagen microsphere with innovative spatial structure, and its design, preparation process, and use. The gene sequence of humanized type III collagen is designed and constructed, and cut by a cutting enzyme and then cyclized by cyclase, obtaining the recombinant humanized type III collagen microspheres with an innovative spatial structure, without introducing any foreign insertion gene or modification gene. The collagen microsphere of the present application exhibits a long degradation time and good stability and durability and can exert its various biological effects for a long time, which can better adapt to applications in the pharmaceutical and cosmetics industries.

Abstract: The present invention is directed to anti-fingerprint coating compositions, the coating layers and coated articles formed therefrom, the preparation methods therefor, and the uses thereof. The coating compositions and methods according to the present invention are capable of forming a coating layer with anti-fingerprint performance. The coating layer according to the present invention comprises a stationary phase impregnated with a mobile phase that can diffuse and fade fingerprints, in addition to optionally having a strong liquid repellency that minimizes the deposition of fingerprints and eases the cleaning of the coated articles.
