However, its utility is constrained by the low surface hardness and inadequate wear resistance. Micro-arc oxidation (MAO) technology emerges as a surface modification method characterised by a straightforward process and superior processing efficacy, making it particularly favoured in enhancing the wear resistance of Ti6Al4V. This paper commenced by elucidating the fundamental principles of micro-arc oxidation. Subsequently, it examined the impacts of crucial parameters such as electrolyte type, concentration, processing voltage, current, time, and electrolyte additives on the friction and wear properties of Ti6Al4V alloy MAO coatings, proposing three mechanisms for optimising wear resistance. The primary strategies for augmenting the microhardness and wear resistance of Ti6Al4V alloy MAO coatings involved pore reduction even sealing, lubrication enhancement, and hard compound generation. Following this, the article synthesised the friction and wear attributes of MAO coatings in conjunction with diverse modification techniques, alongside a review of fretting wear characteristics of Ti6Al4V alloy MAO coatings. Lastly, conclusions and prospects were presented to furnish a foundation for future exploration into the wear resistance of Ti6Al4V alloy MAO coatings in scholarly endeavours.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70000","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726789","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}

Currently, most implants are typically limited to excelling in only one of these functions. A promising approach to achieving a synergistic effect of interfacial bone integration and energy dissipation is the design of a nanofiber-chitosan (nanofiber-CS) composite flexible coating on titanium alloy surfaces. However, the tribological properties of this flexible coating remain uncertain. In this study, the authors evaluated the tribological properties of pure titanium substrates and the nanofiber-cs composite flexible coating in both dry and wet environments. The results demonstrated that while the nanofiber-cs composite flexible coating reduced surface wear in dry conditions, it increased surface wear in wet environments. This indicates that there is potential for improvement in the tribological characteristics of the nanofiber-cs composite flexible coating, particularly in wet conditions. This research offers theoretical and technical insights into the design of flexible coatings for implant surfaces from a tribological standpoint.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689387","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}

A bionic multilayer vascular model that conforms to the real vascular morphology and mechanical properties of arterial vessels can help surgeons familiarise themselves with the mechanical properties of blood vessels in preoperative simulations and thus avoid the risk of intraoperative vascular puncture. In this paper, porcine abdominal aortic vessels were used as a biological model to evaluate its mechanical properties by T-peel test, uniaxial tensile test and puncture force test. The results showed that the average delamination force between the intima and media of the vessels was 1.11 N. The radial tensile strength of the vessels was greater than the axial tensile strength and the elongation at the break of the media increased after peeling the intima. A multilayer vascular model manufacturing method was developed, and the structural integrity was improved using an intima–media nesting method. This research provides guidance for material selection and preparation processes for 3D printed bionic multilayer lower limb vascular models and contributes to the development of more accurate and functional 3D printed vascular models for biomedical applications.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571265","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}

Only symptomatic treatment is possible through bioactive molecules. This study aims to investigate the biolubrication properties of natural and modified phytoglycogen nanoparticles (PGNPs) which have shown superlubricious behaviour at mica-mica sliding interface. PGNPs were cationised (CPGNPs) by modifying hydroxyl groups into quaternary amine groups. Dynamic light scattering (DLS) was used to characterise the size and zeta-potential of both the PGNPs. The quartz crystal microbalance with dissipation (QCM-D) was used to investigate their adhesion to collagen type II and mucin. The tribological properties of the nanoparticles were studied using the polydimethylsiloxane (PDMS)-glass system, cartilage-glass (synovial) and eye-eyelid (ocular) systems. CPGNPs adhered better than PGNPs on synovial and ocular surfaces. Both particle types showed good lubrication for cartilage but no differences between PGNPs and CPGNPs in the eye-eyelid system were observed. Overall, the CPGNPs showed better lubrication properties than PGNPs. PGNPs and CPGNPs were observed to have good lubricating properties in the cartilage-glass system, indicating to great potential towards a possible implementation in the treatment of osteoarthritis.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571266","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}

The large specific surface area of Cu@CuS nanocages enables efficient capture of biotin antibodies, leading to the direct amplification of the signal through the inhibition of electron transport in the redox process of Cu, eliminating the need for universal redox electron mediators. Additionally, Au NPs on the surface of Cu@CuS can accelerate charge transfer and conjugate with anti-PSA. The hierarchical morphology and structure of Cu@CuS nanocages were characterised using scanning electron microscopy and transmission electron microscopy. The fabrication process of the immunodevice was monitored using cyclic voltammetry and electrochemical impedance spectroscopy analyses. PSA was sensitively detected using differential pulse voltammetry on this proposed immunodevice within a linear range from 0 to 100 ng/ml (R2 = 0.996), achieving a low detection limit of 0.077 ng/ml. In addition, the practicality of the developed immunosensor has been proven by successfully detecting PSA in human serum samples obtained from clinical settings. The integration of electrochemical sensors and microfluidic devices holds promise for developing cost-effective approaches in clinical immunoassays.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.12090","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118872","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}

The idea is to propose a method where polyvinylsiloxane impressions, as used in many dental practices, can be combined with surface texture analysis for a rapid, non-invasive, and inexpensive approach to detect and monitor the progression of tooth wear at fine scales over short durations and help determine causal agents of dental tissue loss. We employed both in vitro experimentation and in vivo analysis for abrasion and erosion of enamel and dentin surfaces. Three-dimensional point clouds of impression surfaces were generated using a scanning confocal profiler and analysed using both standard ISO and scale-sensitive fractal analysis approaches. The authors’ results indicate that texture attributes distinguish sound, abraded, and eroded surfaces. Furthermore, microwear textures can parse erosive tooth wear by the causal pH level and duration of exposure. These and other related studies indicate that dental microwear texture analysis holds potential for determining the aetiology of pathological tooth wear and for the clinical assessment and monitoring of dental patients at risk for excessive dental tissue loss at fine scales over short intervals.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.12089","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423871","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, the authors utilise atomic force microscopy to monitor changes in the surface morphology of an enamel mimic, hydroxyapatite (HA), induced by hard seltzer and kombucha. The primary causes of enamel degradation were assessed through a combinatorial investigation probing the impact of carbonation, acid type, acid concentration, and saliva. The average surface roughness of HA discs was determined after successive demineralisation steps. The heterogeneity of the decay process was assessed using multiple spatial replicates per sample. To aid in the interpretation of the HA decay profiles, pH and titratable acidity of each beverage were also measured. The authors find that, in comparison to a reference sample of Coca-Cola®, kombucha is equally erosive after prolonged exposure while hard seltzer results in relatively minor surface damage. In addition, the presence of saliva was found to eliminate any measurable amounts of decay. Results from this study demonstrate the potential damage more recently popularised beverages can have on dental enamel and the significant dependence of oral health on the presence of saliva.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.12088","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423939","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}
