Collagen VI microfibril structure reveals mechanism for molecular assembly and clustering of inherited pathogenic mutations [PDF]

Nature Communications
Collagen VI links the cell surface to the extracellular matrix to provide mechanical strength to most mammalian tissues, and is linked to human diseases including muscular dystrophy, fibrosis, cardiovascular disease and osteoarthritis.

SANS investigation of fungal loosenins reveals substrate-dependent impacts of protein action on the inter-microfibril arrangement of cellulosic substrates [PDF]

Biotechnology for Biofuels and Bioproducts
Background Microbial expansin-related proteins include fungal loosenins, which have been previously shown to disrupt cellulose networks and enhance the enzymatic conversion of cellulosic substrates.

Fabrication of Ionic Cellulose Nanofiber Composites by Electrospinning Cellulose Microfibril-Gel-Dispersions in Poly(vinyl Alcohol) Solution

Journal of Natural Fibers, 2022
In this study, we propose a fabrication method to obtain composites of poly(vinyl alcohol) (PVA)/ionic cellulose nanofibers, in which a fiber structure is manipulated through a reconstruction of 2,2,6,6-tetramethyl-piperidinyl-1-oxyl radical (TEMPO ...

Microfibril-associated protein 5 and the regulation of skin scar formation

Scientific Reports, 2023
Many factors regulate scar formation, which yields a modified extracellular matrix (ECM). Among ECM components, microfibril-associated proteins have been minimally explored in the context of skin wound repair.

Influence of defects on the tensile behaviour of flax fibres: Cellulose microfibrils evolution by synchrotron X-ray diffraction and finite element modelling

Composites Part C: Open Access, 2022
The cellulose microfibril realignment of unitary flax fibres with contrasted density of structural defects, which are also known as dislocations and defined as zones of microstructure heterogeneities, was investigated upon tensile testing by means of X ...

Nanomechanics of collagen microfibrils [PDF]

Muscle Ligaments and Tendons Journal, 2013
Collagen constitutes one third of the human proteome, providing mechanical stability, elasticity and strength to organisms and is thus the prime construction material in biology. Collagen is also the dominating material in the extracellular matrix where its stiffness controls cell differentiation, growth and pathology.

Corneal stroma microfibrils [PDF]

Experimental Eye Research, 2015
Elastic tissue was first described well over a hundred years ago and has since been identified in nearly every part of the body. In this review, we examine elastic tissue in the corneal stroma with some mention of other ocular structures which have been more thoroughly described in the past.

Strong PP/PTFE microfibril reinforced composites achieved by enhanced crystallization under CO2 environment

Polymer Testing, 2022
In-situ polypropylene/polytetrafluoroethylene (PP/PTFE) composites are amazing and promising materials because continuous PTFE fibrils can be dispersed in polymer matrix randomly and uniformly, and meanwhile, PTFE microfibrils can greatly enhance the ...

Simulation of Adhesive Contact of Soft Microfibrils

Lubricants, 2020
Adhesive contact between a flat brush structure with deformable microfibrils and an elastic half space is numerically simulated. The stiffness of pillars is modeled by linear springs.
