Evidence-based biomaterials research

The fast development of biomaterials science and engineering has generated significant number of studies and publications as well as tremendous amount of research data.A methodology is needed to translate such research data and results to validated scientific evidence.This article for the first time proposes the concept and methodology of evidence-based biomaterials research,which is to use evidence-based research approach represented by systematic reviews to generate evidence for answering scientific questions related to biomaterials.After briefly introducing the advancement of biomaterials since 1950s,the scientific and engineering nature of biomaterials are discussed along with the roadmap of biomaterials translation from basic research to commercialized medical products,and the needs of scientific evidence.Key information of the evidence-based approach such as its origination from evidence-based medicine,levels of evidence,systematic review and meta-analysis,differences between systematic and narrative reviews is then highlighted.Applications with a step-by-step procedure of conducting evidence-based biomaterials research,three examples of biomaterials research using evidence-based approach to generate scientific evidence,and opportunities and challenges of evidence-based biomaterials research are presented.With its notable impact on the practice of medicine,the evidence-based approach is also expected to make influential contributions to the biomaterials field.

Key progresses of MOE key laboratory of macromolecular synthesis and functionalization in 2022

In 2022,The MOE Key Laboratory of Macromolecular Synthesis and Functionalization in Zhejiang University had achieved several important results.First,a series of well-defined dinuclear organoboron catalysts were developed to precisely control the enchainment of ether and carbonate segments during the copolymerization of CO_(2)and epoxides.Second,polyester had been synthesized through cationic copolymerization of cyclic anhydride.Third,ring-opening polymerization of carbon dioxide based valerolactone had been achieved,revealing the prospect of 3-ethylidene-6-vinyltetrahydro-2H-pyran-2-one(EVL)in utilizing CO_(2)and synthesizing functional polymers.Fourth,machine learning methods have been applied to biomaterial research,enabling high-throughput screening of functional biomaterial surfaces for implantable devices,and searching for potent antimicrobial peptides in whole combinatorial peptide libraries.Fifth,methods of characterization of biomacromolecule RNA transcription and manipulation of nucleoside modification were developed.Sixth,artificial enzymes-armed Bifidobacterium Longum probiotics were established to tune down gut inflammation.Seventh,three-dimensional(3D)printing technologies were used to engineer tough supramolecular hydrogels.Eighth,hydroplastic foaming graphene frameworks for acoustic and conductive polymer composites were provided for application.Ninth,aggregate photophysics about the nature of through-space interactions(TSIs)and manipulating their strength in small molecules with non-conjugated structure had been elucidated.Tenth,the forming mechanism of a newfound nested texture in poly(L-lactic acid)(PLLA)spherulitic films had been revealed.Finally,the isotropically dyeing mechanism of KDP single crystals grown from hydrogels have been explored.The related works are reviewed in this paper.
