Frictional properties of physically cross-linked PVA hydrogels as artificial cartilage

Mechanically Tough Pluronic F127/Laponite Nanocomposite Hydrogels from Covalently and Physically Cross-Linked Networks

Photochemical Patterning of Ionically Cross-Linked Hydrogels

Iron(III) cross-linked alginate hydrogel incorporating sodium lactate undergoes photoinduced degradation, thus serving as a biocompatible positive photoresist suitable for photochemical patterning. Alternatively, surface etching of iron(III) cross-linked hydrogel contacting lactic acid solution can be used for controlling the thickness of the photochemical pattering. Due to biocompatibility, bo...

Effect of Irradiation on the Strength and Lubricity of PVA-PAA Hydrogels for Cartilage Repair

Introduction: Repairing cartilage is an ongoing challenge due to the limited autonomous healing ability of cartilage, and the lack of long term intervention strategies. Therefore, there is a great need for engineered biomaterials for cartilage replacement therapy to delay further invasive treatments. Hydrogels have been explored for this purpose. Polyvinyl alcohol (PVA) hydrogels are one of the...

Hydrogels Prepared from Cross-Linked Nanofibrillated Cellulose

Nanocomposite hydrogels were developed by cross-linking nanofibrillated cellulose with poly(methyl vinyl ether-co-maleic acid) and polyethylene glycol. The cross-linked hydrogels showed enhanced water absorption and gel content with the addition of nanocellulose. In addition, the thermal stability, mechanical strength, and modulus increased with an increase in the amount of nanocellulose in hyd...

Development and Evaluation of Polyvinyl Alcohol-Hydrogels as an Artificial Atrticular Cartilage for Orthopedic Implants

Due to its excellent biocompatibility and mechanical properties, various different applications of polyvinyl alcohol-hydrogels (PVA-H) has been attempted in many fields. In the field of orthopedic surgery, we have been engaged for long time in research on the clinical applications of PVA-H as a artificial cartilage, and have performed many basic experiments on the mechanical properties, synthes...
