Hydrogels are highly promising materials for fabricating artificial cartilage owing to their excellent biocompatibility and lubricity. Inspired by natural articular cartilage, in this study, we designed a modification strategy to enhance the lubricity of double-network (DN) hydrogels. Specifically, two lubricating substances, nonionic surfactant Tween 80 and hydrogenated soybean phosphatidylcholine (HSPC), were incorporated into a DN hydrogel. Lubricity-enhanced DN hydrogel exhibited superlubricity through the synergistic effect of Tween 80 and HSPC, with a low coefficient of friction of 0.008, which remained stable after 6 h of continuous tribological testing. In addition, the mechanical properties of lubricity-enhanced DN hydrogel were greater than those of unmodified DN hydrogel, with a 29% increase in fracture strain and a 1.7-fold increase in toughness. Tween 80 micelles reinforced the physically cross-linked network through hydrogen bonding with the DN hydrogel, whereas HSPC vesicles encapsulated in the polymer network served as reinforcement nodes to enhance the chemically cross-linked network. As a result, lubricity-enhanced DN hydrogel exhibited both excellent lubricity and mechanical properties. This study demonstrates an innovative way to design hydrogels exhibiting both superlubricity and excellent mechanical properties, broadening the applications of DN hydrogels in the field of artificial joint cartilage.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944921","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, we proposed the introduction of high-purity iron beads as external deoxidisers to inhibit the oxidation of Zr2.5Nb during thermal nitriding and investigated the biotribological properties of this alloy after deoxidation. Zr2.5Nb samples were subjected to deoxidation thermal nitriding at 900°C and 1000°C for 4 h. The main phase on the surface was ZrN, which was accompanied by a minor phase of unsaturated zirconium oxides (ZrO0.33, ZrO0.27). The thickness of the ZrN ceramic layer increased from 5.26 ± 0.37 μm to 7.78 ± 0.19 μm. During electrochemical friction–corrosion test, the open-circuit potential (OCP) and coefficient of friction (COF) values for the sample prepared at 900°C were −809.8 mV and 0.3015, and those for the sample prepared at 1000°C were −682.3 mV and 0.3168. The samples that underwent deoxidation thermal nitriding exhibited better friction–corrosion resistance and a lower friction coefficient than the original sample. Additionally, the volume wear loss was reduced by 50.53% and 62.27%, also demonstrating the superior biotribological properties achieved through deoxidation thermal nitriding.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143857136","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}

This study systematically investigated the tribological behaviour of the finger and physiological response of the brain related to the width recognition of tactile perception using subjective evaluation, friction and electroencephalography methods. The results show that the texture feeling, recognition accuracy of the texture and proportion of deformation friction increased with the texture width. The average width recognition threshold of the fine texture was 45.4 μm. The load index, maximum amplitude of the vibration signal, entropy, longest vertical line and P300 amplitude were positively correlated with the texture width. P300 latency was negatively correlated with the texture width. When the texture width exceeded the width recognition thresholds of tactile perception, the main frequency of the vibration signals increased to the optimal perceptual range of the Pacinian corpuscle. The nonlinear features of the vibration signal increased, and the vibration system transitioned from a homogenous state to a disrupted state. Moreover, the activation intensity and area of the brain and the speed of tactile recognition increased. The study demonstrated that the mechanical stimuli of friction and vibration generated in the touching of fine textures having various widths affected the subjective evaluation and brain response.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831360","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}

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.

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.

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.

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.
