bio tribology of vascular devices a review of tissue device friction research
Biotribology, 2021Co-Authors: Rasmus Wagner, Raman Maiti, M J Carre, Cecile M Perrault, Paul C Evans, R LewisAbstract:Abstract Vascular medical devices, such as stents, catheters and more advanced devices inevitably interact with surfaces within the human body. These interactions and the underlying biological and tribological (friction) mechanisms and resulting implications are not well understood, currently. For the further optimisation of these devices and the development of new and safer devices, a deeper understanding of vascular Biotribology is required. Studies about this topic are scarce and no review is available. This review paper introduces vascular physiology relevant to interaction with medical devices and highlights where tribological effects may come into play. Furthermore, implications with existing medical devices are investigated in the context of Biotribology and relevant studies are discussed. The different approaches to study the interactions are compared, and the current state of the field is reviewed. The aim of this paper is to provide an introduction to this interdisciplinary field, for both researchers with an engineering background and those with a biological background, and to present the current state of the field of research.

Lubrication of soft oral surfaces
Current Opinion in Colloid and Interface Science, 2019Co-Authors: Anwesha Sarkar, Efren Andablo-reyes, Duncan Dowson, Michael Bryant, Anne NevilleAbstract:Abstract Oral lubrication deals with one of the most intricate examples of Biotribology, where surfaces under sliding conditions span from the hardest enamel to soft oral tissues in human physiology. Complexity further arises with surfaces being covered by an endogenous biolubricant saliva before exogenous food particles can wet, stick, or slip at the surfaces. In this review, we present a description of soft oral surfaces, comparing them with the recent approaches that have been used to study oral lubrication using in vitro to ex vivo setups. Specifically, lubrication behaviors of saliva and soft microgels are discussed highlighting instances of hydration lubrication. We have structured this information creating a strong link between theoretical concepts and oral lubrication, which has thus far remained elusive in literature. Finally, we highlighted some of the several challenges remaining in this field and discussing how emerging technologies in material science might help overcoming them.

Biotribology of the ageing skin—Why we should care
Biotribology, 2019Co-Authors: Georges Limbert, Damien Pond, Rikeen Jobanputra, Michael J. Sherratt, Helen K Graham, Marc Arthur Masen, Andrew McbrideAbstract:Ageing of populations has emerged as one of the most pressing societal, economic and healthcare challenges currently facing most nations across the globe. The ageing process itself results in degradation of physiological functions and biophysical properties of organs and tissues, and more particularly those of the skin. Moreover, in both developed and emerging economies, population ageing parallels concerning increases in lifestyle-associated conditions such as Type 2 diabetes, obesity and skin cancers. When considered together, these demographic trends call for even greater urgency to find clinical and engineering solutions for the numerous age-related deficits in skin function. From a tribological perspective, detrimental alterations of skin biophysical properties with age have fundamental consequences on how one interacts with the body's inner and outer environments. This stems from the fact that, besides being the largest organ of the human body, and also nearly covering its entirety, the skin is a multifunctional interface which mediates these interactions. The aim of this paper is to present a focused review to discuss some of the consequences of skin ageing from the viewpoint of Biotribology, and their implications on health, well-being and human activities. Current and future research questions/challenges associated with Biotribology of the ageing skin are outlined. They provide the background and motivation for identifying future lines of research that could be taken up by the Biotribology and biophysics communities.

Modeling and Simulation in Tribology Across Scales : an Overview
Tribology International, 2018Co-Authors: Antonis I Vakis, Vladislav A. Yastrebov, Clotilde Minfray, Andreas Almqvist, Daniele Dini, Julien Scheibert, Lucia Nicola, Marco Paggi, Georges LimbertAbstract:This review summarizes recent advances in the area of tribology based on the outcome of a Lorentz Center workshop surveying various physical, chemical and mechanical phenomena across scales. Among the main themes discussed were those of rough surface representations, the breakdown of continuum theories at the nano- and microscales, as well as multiscale and multiphysics aspects for analytical and computational models relevant to applications spanning a variety of sectors, from automotive to Biotribology and nanotechnology. Significant effort is still required to account for complementary nonlinear effects of plasticity, adhesion, friction, wear, lubrication and surface chemistry in tribological models. For each topic, we propose some research directions.
