Synthesis of high-quality monolayer tungsten disulfide with chlorophylls and its application for enhancing bone regeneration

摘要: Due to the population explosion of 21st century, nearly one billion people are over 64 years age and bone fracture is most frequent problems facing both sexes because osteoporosis. However, difficulty in enhancing regeneration repair poses challenges thus, a two-dimensional monolayer material (i.e. tungsten disulfide (WS2)) could be candidates offering possible solution problem. Here, we prepare high-quality WS2 thin sheets large quantity with assistance extracted chlorophyll molecules, natural pigment used photosynthesis, via liquid-phase exfoliation method. Then, exfoliated were mixed polycaprolactone (PCL)/calcium silicate (CS) form biocompatible WS2-based composite. The vivo experiments show that composite was 120% superior commercially available mineral trioxide aggregate (MTA) cement. Moreover, mechanical properties exhibited ~300% enhancement PCL/CS, which commonly materials. Our findings highlight prospects for towards improvement applications.
