What is biofilm? Biofilms are defined as communities of micro-organisms attached to a surface, or one another, and encased within a matrix of extracellular polymeric substance (EPS). The EPS makes up the largest component of the biofilm, and in the biological environment is generally composed of polysaccharides, proteins, glycolipids, blood products, cellular debris, extracellular enzymes, metal ...
At present, it has become the metal material of choice for replacement or repair products such as artificial joints, artificial bones, broken bone fixators, spine correction rods, intramedullary nails, artificial heart valves, dental implants, and skulls. Here is an introduction to the medical implantation of nitinol products and porous titanium products ...
Results: The ePTFE implants had significantly higher abscess formation scores f Results: The ePTFE implants had significantly higher abscess formation scores for both S. aureus and E. coli inoculations compared to that of HAV. ...
In calcium phosphate ceramics, hydroxyapatite (HAP) can form chemical bonding with cartilage tissue due to its molecular structure and calcium-phosphorus ratio, which are very similar to the inorganic components of normal bone and have excellent biological activity and osteoinductivity. In the implantation of bone defect, there is no fibrous tissue interface between bone tissue ...

EyeYon's new product, now on an accelerated path as a Breakthrough Device, is an Artificial Endothelial Layer - EndoArt® - a polymer film implant, attached to the posterior corneal surface, to treat chronic corneal edema secondary to endothelial dysfunction. ...
Following BTLT implantation on the surface of the liver in mice expressing the mutant human form of alpha-1 antitrypsin (PiZ mouse), human albumin, transferrin, alpha-1 antitrypsin (AAT) and fibrinogen were detected in the circulation as early as 7 days, with increasing levels of human albumin detected for at least 90 days post-implantation. ...
NanoMech has developed patented platform nanotechnology innovations in machining and manufacturing, lubrication and energy, adaptive chemistries for advanced textile coatings, metal surface coatings, biomedical implant coatings, and strategic military applications; and Matthew Putnam, Chief Executive Officer of Nanotronics Imaging. ...
Microporous surfaces of commercially available uncemented Tilastan® implants were coated with gentamicinpalmitate. The roughness of the titanium implant surfaces remained largely intact. During the first few days, the gentamicin release was comparable to the elution of this antibiotic from commercially available PMMA bone ...
However, whether this process significantly influences the coated surface morphology and cellular responses still needs to be systematically studied and documented. In this investigation, the morphology, composition and resultant surface roughness of the nHA coating surfaces were examined, prior to in vitro cytocompatibility, proliferation and ...
