New hybrid acrylic/collagen nanocomposites and their potential use as bio-adhesives
(Elsevier, 2020-07)
Nowadays material science is trying to design products that combine the adaptability of synthetic polymers with the structure and functionality of biopolymers. In this context, the present work investigates the production ...
Effect of nano-sized bioactive glass particles on the angiogenic properties of collagen based composites
(Springer, 2013-02-22)
Angiogenesis is essential for tissue regeneration and repair. A growing body of evidence shows that the use of bioactive glasses (BG) in biomaterial-based tissue engineering (TE) strategies may improve angiogenesis and ...
Differences in the energetics of collagen denaturation in connective tissue from two muscles
(Elsevier Science, 2018-07)
The thermal denaturation of collagen the perimysium of intramuscular connective tissue isolated from bovine Semitendinosus (ST) and Perctoralis profundus (PP) muscles was investigated using a range of heating rates in ...
Collagen-silica nanocomposites as dermal dressings preventing infection in vivo
(Elsevier Science, 2018-12)
The controlled delivery of multiple drugs from biomaterials is a timely challenge. In particular the nanocomposite approach offers a unique opportunity to combine the scaffold-forming ability and biocompatibility of hydrogels ...
Silica-collagen bionanocomposites as three-dimensional scaffolds for fibroblast immobilization
(Elsevier, 2010-10)
Silica-collagen bionanocomposite hydrogels were obtained by addition of silica nanoparticles to a protein suspension followed by neutralization. Electron microscopy studies indicated that larger silica nanoparticles (80 ...
A collagen‐silica‐ based biocomposite for potential application in bone tissue engineering
(Wiley-liss, div John Wiley & Sons Inc., 2021-08)
Bone is a hierarchical material that has inspired the design of biopolymer-derived biocomposites for tissue engineering purposes. The present study sought to synthesize and perform the physicochemical characterization and ...
Dodecenylsuccinic anhydride modified collagen hydrogels loaded with simvastatin as skin wound dressings
(Veterinary and Human Toxicology, 2019-05)
Skin wound healing presents a unique challenge because of its complex healing process. Herein, we developed a hydrophobic wound dressing to incorporate simvastatin, which has potential application in the treatment of ulcers ...
Evaluation of antibacterial and cytotoxic effects of nano-sized bioactive glass/collagen composites releasing tetracycline hydrochloride
(Wiley Blackwell Publishing, Inc, 2014-06)
Aims: To evaluate the antibacterial efficacy of silicate bioactive glass nanoparticles/collagen composites functionalized with tetracycline hydrochloride (TCH). Methods and Results: Different concentrations of tetracycline ...
Influence of silicification on the structural and biological properties of buffer-mediated collagen hydrogels
(Wiley VCH Verlag, 2012-03)
A buffer-mediated gelation route for collagen hydrogels that allows the formation of homogeneous composite and hybrid materials with various silica sources (i.e., colloidal silica and soluble silicates) at high concentration ...
Collagen and chitosan blends for 3D bioprinting: A rheological and printability approach
(Elsevier, 2019-12)
Collagen and chitosan are widely employed as biomaterials, including for 3D-bioprinting. However, the use of collagen and chitosan (col:chi) blends as bioinks is still scarce. In this work, the rheology of different hydrogel ...
