Herein, we present a novel and simple long straight bundle electrospinning strategy inspired by Darwin's bark spider to prepare 3D aligned fibre aerogels. Different from the conventional electrospinning, whipping instability of the fibre is effectively eliminated by manipulating the distribution of electric field lines during the long straight bundle electrospinning, resulting in the formation of a 3D aligned fibre aerogel. The detailed long straight bundle electrospinning process (formation of fibre bundle, flying path of fibre bundle and deposition of fibre bundle) along with the underlying mechanism are systematically studied. Based on this theoretical basis, scalable fabrication of the 3D flexible aligned fibre aerogel with an ultrahigh fibre alignment degree of 0.93 and an ultrathick structure (2.8 cm) is achieved in one step. As a proof of concept, we investigate the use of the 3D aligned fibre aerogel in air filtration. It is found that the fibre aerogel shows excellent PM1.0 and PM2.5 filtration performance in both perpendicular to and parallel to fibre alignment direction. Interestingly, the pressure drop in the direction parallel to fibre alignment is only 21 Pa, which is much lower than that in the direction perpendicular to fibre alignment. We also compare the filtration performance of our 3D fibre aerogel with other filters and find that the comprehensive performance of our aerogel is obviously better.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"12 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683289","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}

Stent intervention is one of the main methods for treating CVD due to its advantages of minimal trauma, fast recovery and fewer complications. However, the main function of existing drug-eluting stents is anti-hyperplasia, and their re-endothelialisation function is still insufficient and needs to be strengthened. In this study, a novel coating containing traditional Chinese medicine ingredient, Ophiopogon Saponin D (OPH), is designed to enhance the re-endothelialisation function of stents: firstly, the dopamine (DA) and hexanediamine (HD) were co-polymerised to the bare metal stent, endowing rich-amino surface (PDA/HD) for conjugating functional molecules by chemical reaction; thereafter hyaluronic acid (HA) containing OPH were conjugated to the PDA/HD. Our data suggested that the OPH coating promoted surface re-endothelialisation not only by directly enhancing proliferation/migration and inhibiting apoptosis of endothelial cells, but also by regulating macrophages to M2 phenotype and smooth muscle cells to contractile phenotype. Our study may provide inspiration for designing more novel biomaterial coatings using traditional Chinese medicine ingredient.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"12 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146217297","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 relate the subcutaneous pressure and the brain response induced by pain sensations, a mathematical model was established based on the finite element model, Hodgkin–Huxley model and GCT model. The results showed that stronger subcutaneous pressure stimulation can lead to higher frequency of the membrane potential and T-cell potential. The frontal, prefrontal cortex, primary somatosensory cortex and occipital lobe were involved in the processing of pressure pain. A significant increase was observed in γ oscillations in pain states compared with no pain, but no significant differences in different pain level, indicating mathematical model and EEG methods can distinguish the pain but cannot distinguish the pain intensities when the stimulation exceeded the pain threshold. Compared with silicone materials, a higher T-cell potential and a lower pressure pain threshold were observed as the skin contacted with foam materials, suggesting that the foam materials can induce more severe pain on the skin surface. This study is helpful to understand the mechanisms of pain from skin surface to brain response and to provide theoretical guidance for the optimal design of lower limb prostheses.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"12 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146193491","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 difference in wear assessments of unicompartmental knee prosthesis under total knee loading mode and unicompartmental loading mode was investigated via computational simulation. The ISO standard testing protocol and the measured personalised load and kinematic data were further used to reveal the influence of the testing parameters on wear assessments. Compared with the total knee loading mode, the unicompartmental loading mode produced a larger peak contact pressure of the tibial insert throughout the wear cycle. Under ISO 14243-3 and Stan’s CAMS testing parameters, the predicted volumetric wear of tibial inserts of the unicompartmental loading mode increased by 28.21% and 15.18%, respectively, compared with the total loading mode. Compared with ISO 14243-3, volumetric wear increased by 42.64% for total knee loading mode and 28.14% for unicompartmental loading mode under Stan’s CAMS loading conditions. Both loading mode and parameters played an important role in the wear of unicompartmental knee arthroplasty simulation. Therefore, wear testing and computational simulation of wear predictions for unicompartmental knee prostheses should be performed in a unicompartmental loading mode, and it is more reasonable to use the patient’s in vivo measurement data.","PeriodicalId":52235,"journal":{"name":"Biosurface and Biotribology","volume":"11 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/bsb2.70015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145619139","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}
