Document Type and Number:
WIPO Patent Application WO/2024/027195
Kind Code:
A1
Abstract:
Disclosed are a method for processing a biofilm material, the biofilm material and an artificial biovalve. The method for processing the biofilm material comprises: pretreating a biofilm, such that the biofilm has loaded thereon a first reagent and a second reagent, the volatility of the first reagent being greater than that of the second reagent; and performing drying treatment on the pretreated biofilm, such that the dried biofilm at least retains part of the second reagent. According to the present application, by introducing two reagents having different volatilities into the biofilm and relying on thermodynamic principles for the removal of a volatile reagent from the biofilm, the thickness of the biofilm is reduced, there is little damage to the collagen fiber structure of the biofilm, the biofilm is not prone to permanent mechanical damage, and the use performance of the biofilm is ensured.
