Biodegradable injectable polyurethanes: Synthesis and evaluation for orthopaedic applications

Novel quinoline-based polyurethane elastomers. The effect of the hard segment structure in properties enhancement

“…The usage of monomers with different functionalities is a possible route for the development of both linear and cross-linked polyurethanes having the design flexibility required for engineering applications. Also, a large number of these polyurethanes are biodegradable polymers with a wide variety of chemical and mechanical properties which make them useful in biomedical applications [5][6][7][8][9][10]. The wide range of polyurethane elastomer properties are directly linked to their two-phase microstructure, with hard domains acting as thermally reversible crosslinking points [11].…”

A novel glucose biosensor based on phosphonic acid-functionalized silica nanoparticles for sensitive detection of glucose in real samples

“…In addition, the functional P O bond is an important component of phospholipid in the cell membrane. So adding the P O bond (phosphates group) into biomaterials can be considered as bionic building to improve the biocompatibility of general materials [21,22]. Phosphonic acid-functionalized materials are predicted to be widely exploited especially in enzyme immobilization supports and environmentally benign applications in the near future.…”

Biodegradation of polyurethanes and nanocomposites to non-cytotoxic degradation products

“…The soft segment provides the elastomeric character to the polymer backbone [1,2]. Physicochemical properties of these polymers are directly related to the chemical composition, molecular weight and ratio of hard and soft segments [3,4].…”
