Microfluidic Spinning of PEDOT:PSS Microfibers for Nerve Guidance Conduits

Advanced Materials Technologies, EarlyView.
This publication explores the fabrication of microfluidically spun PEDOT:PSS microfibers for conductive nerve guidance conduits (NGCs). It details the spinning process, fiber characterization, and biocompatibility assessment. The study highlights the fibers' mechanical and electrical properties, non‐cytotoxicity, and potential for nerve regeneration or

Physiological mechanical forces accelerate the degradation of bovine lung collagen fibers by bacterial collagenase

Scientific Reports
Collagen fibers, one of the key load-bearing components of the extracellular matrix, contribute significantly to tissue integrity through their mechanical properties of strain-dependent stiffening.

Effects of Copper and Cross-Linking on the Extracellular Matrix of Tissue-Engineered Arteries

Cell Transplantation, 2005
In many cases, the mechanical strengths of tissue-engineered arteries do not match the mechanical strengths of native arteries. Ultimate arterial strength is primarily dictated by collagen in the extracellular matrix, but collagen in engineered arteries ...

Conjecture on the lateral growth of type I collagen fibrils [PDF]

arXiv, 2013
Type I collagen fibrils have circular cross sections with radii mostly distributed in between 50 and 100 nm and are characterized by an axial banding pattern with a period of 67 nm. The constituent long molecules of those fibrils, the so-called triple helices, are densely packed but their nature is such that their assembly must conciliate two ...

Growth Factor‐Loaded Mesoporous Silica Particles, Incorporated in Electrospun PCL Fibres, Provide Topographical and Chemical Cues for Tendon Tissue Engineering

Advanced Materials Technologies, EarlyView.
Electrospinning enables the hierarchical assembly of nanofiber‐based scaffolds for tissue engineering. However, encapsulated proteins often undergo structural changes. This study used mesoporous silica nanoparticles (MSNs) as protective carriers, mitigating protein denaturation and supporting controlled release.

Estrogen depletion and drug treatment alter the microstructure of type I collagen in bone

Bone Reports, 2016
The impact of estrogen depletion and drug treatment on type I collagen fibril nanomorphology and collagen fibril packing (microstructure) was evaluated by atomic force microscopy (AFM) using an ovariectomized (OVX) rabbit model of estrogen deficiency ...

Mineral and cross-linking in collagen fibrils: The mechanical behavior of bone tissue at the nano-scale [PDF]

arXiv
The mineralized collagen fibril is the main building block of hard tissues and it directly affects the macroscopic mechanics of biological tissues such as bone. The mechanical behavior of the fibril itself is determined by its structure: the content of collagen molecules, minerals, and cross-links, and the mechanical interactions and properties of ...

Multifunctional Fibrous Mats: Stretchable, Conductive, and Hydrophilic Platforms for Wearable Electronics

Advanced Materials Technologies, EarlyView.
A hydrophilic, stretchable, nonwoven electrospun fiber mat targeted to be applied in long‐term bioelectronic devices. By incorporating amphiphilic polyethylene glycol block copolymers in a polydimethylsiloxane matrix, the material develops stable hydrophilicity, enhanced breathability, as well as enhanced adhesion to cells.

Improving the crosslinking of collagen casing and glutaraldehyde by facilitating the formation of conjugate structure via pH

Collagen and Leather
Glutaraldehyde (GTA) crosslinking is commonly used to improve the thermal stability and mechanical strength of collagen casings. The aim of this research was to determine the optimal pH of the crosslinking between GTA and collagen as well as the ...
