Preparation method and application of injectable nanoscale wood and nanoscale wood-collagen implant

Abstract

The invention belongs to the technical field of biomedical materials, and particularly relates to a preparation method and application of injectable nanoscale wood and a nanoscale wood-collagen implant. The nanoscale wood material prepared by a unique delignification-air-induced ultrafine crushing-sieving technology shows excellent injectability; the nano wood-collagen composite implant has the advantages that good injectability, excellent biocompatibility, biological safety and biological activity are kept, and proliferation, adhesion and migration of fibroblasts are remarkably promoted; in the light-aged skin, expression and regeneration of healthy collagen can be remarkably promoted, the corium layer density is improved, the skin elasticity is enhanced, the transepidermal moisture loss is reduced, and the repair process of the light-aged skin is accelerated; wide application potentials are shown in the fields of face filling, artificial skin, artificial bones, stent materials, medical apparatuses and instruments and the like.
