Mimicking such organisations in artificial composite tissue-engineering scaffolds is important for realising functional fixation between ligament implants and host bones. Here, the authors aim to provide a comprehensive review on the latest strategies to fabricate biomimetic composite scaffolds for the regeneration of ligament-to-bone interface. The biomimetic composite scaffolds are divided into stratified and gradient scaffolds, which are characterised as layer-specific and continuous changes, respectively, in scaffold materials and/or microstructures. Biofabrication strategies for different types of composite scaffolds are summarised. The effects of material/structural changes on cellular morphology, cell differentiation, in vivo osteointegration and multi-tissue interface regeneration are highlighted. Finally, the potential challenges and future perspectives in engineering biomimetic composite scaffolds for ligament–bone interface regeneration are discussed.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"7 4","pages":"187-205"},"PeriodicalIF":0.0,"publicationDate":"2021-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.12021","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48634325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, taking the fracture site of the lower one-third of human tibia as an application case, six types of personalised Ti6Al4V tibial plates with grooved surface were designed and evaluated by reverse engineering and finite element analysis. The results showed that the grooved design can reduce the stress shielding rate of bone plate and promote the facture healing. Among the six types of bone plates, the ‘OUT-MI’ bone plate has the lowest stress shielding rate and the most uniform stress distribution. Meanwhile, with the increasing tibial load during the convalescence, the average stress and maximum axial displacement of the tibial fracture surface increased, which can effectively improve the bone regeneration in the tibial fracture area. Moreover, there was no significant difference in four-point bending performance between the ‘OUT-MI’ bone plate and the ‘STR-BE’ bone plate, indicating that the mechanical properties of this bone plate were reliable. The results provide a theoretical basis for the design of fracture fixation plates on clinical treatment.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"7 3","pages":"142-153"},"PeriodicalIF":0.0,"publicationDate":"2021-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.12019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45342045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tissue adhesives based on synthetic polymers generally have good adhesion but are not biodegradable. However, the long-term presence of non-biodegradable adhesives in the body can cause secondary harm to the patient. An ideal tissue adhesive should meet the following requirements: good adhesiveness, biodegradability, low cytotoxicity, and minimal inflammatory response. Natural polymers with inherent biodegradation and biocompatibility show great potentials in biomedical engineering, and the development of tissue adhesives based on natural polymers has become a hot topic in biomaterials science. This review systematically summarises the latest progresses in biodegradable tissue adhesives based on natural polymers, such as chitosan, hyaluronic acid, alginate, gelatin, dextran, and cellulose. Methods for preparing natural polymer tissue adhesives are summarised and their advantages and disadvantages are discussed. Finally, potential trends in the future direction of biodegradable tissue adhesives are discussed.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"7 4","pages":"163-179"},"PeriodicalIF":0.0,"publicationDate":"2021-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.12016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43019982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To understand whether ultrasonic antifouling is suitable for underwater optical windows, the effect of ultrasonic conditions including frequency, power and duration on the removal of microbiofouling on the surface of polymethyl methacrylate (PMMA), a type of common optical material, was investigated in this study by three-factor and three-level orthogonal experiments. Before and after the ultrasonic treatment, both surface morphology and fouling degree of PMMA samples immersed in Escherichia coli suspension and seawater were characterized and quantified using laser scanning microscope. The results showed that ultrasonic treatment can effectively remove microfouling from the PMMA surface under suitable conditions. Ultrasonic technology has a great potential for the control of microfouling on the marine optical instruments. When compared with power and duration, ultrasonic frequency has a more significant effect on antifouling efficacy of ultrasound. It is useful for PMMA samples exposed to seawater within 2 days to conduct an antifouling treatment under the condition of an ultrasonic frequency of 20 kHz, ultrasonic power of 40 W, and ultrasonic duration of 7 min.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"7 3","pages":"119-125"},"PeriodicalIF":0.0,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.12014","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42398478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have unique features, such as a large specific surface area, multiple active sites, easy functionalisation, and adjustable biocompatibility. MOFs have recently been widely used in the field of biomedical engineering owing to their unique structures and properties. This has enabled them to replace traditional materials and effectively address several problems. Through continuous development, MOF-based biomaterials have been remarkably improved by clarifying the relationship between MOF structures and properties. As a result, they are being extensively studied in the fields of chemical and material science. MOF-based biomaterials can meet the growing demands for efficient materials in biomedical applications. This review first discusses the basic structure of MOFs, followed by their preparation and functionalisation methods. The biomedical applications of MOF-based biomaterials in the fields of antibacterial activity, tumour therapy, skin repair, and bone repair are then summarised. Finally, challenges and future perspectives in the biomedical applications of MOF-based biomaterials are outlined.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"7 3","pages":"99-112"},"PeriodicalIF":0.0,"publicationDate":"2021-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.12012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41394852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
