The adsorption properties of metal ions containing hydroxyapatite (Ca10(PO4)6(OH)2,
HAp) were elucidated for the development of protein drug carrier. As-prepared metal ion containing
HAp nanocrystal showed plate-like morphology with 10-20nm in length and 5-10nm in width. The
metal ion containing HAp microparticles had higher specific surface area than the HAp microparticle.
The adsorption amount per unit area of HAp showed higher than those of metal ion containing HAp.
The adsorption behavior followed the Langmuir curves for each protein, indicating the monolayer
adsorption. The loaded amount of proteins could be one of the most important properties for the
application of drug delivery carrier.
A new method for the preparation of biodegradable porous scaffolds has been developed by using preprepared ice particulates as porogen material. A novel kind of hybrid biodegradable porous scaffold has been developed by forming collagen microsponges in the pores or interstices of a synthetic polymer sponge or mesh. A hybrid sponge of synthetic polymer, collagen and hydroxyapatite has been developed for hard tissue engineering. Bovine articular cartilage-like tissue has been engineered by culturing chondrocytes in the PLGA-collagen scaffolds.
Plant fiber concrete in the cement base material (cement, mortar or concrete) to join the natural plant fiber, to form a new type of concrete, its advantages can improve the performance of concrete, concrete to reduce costs, save energy. Understanding straw fibers mixed with concrete, the variation in performance, with the same concrete than different content, physical and mechanical properties of the different shapes straw fiber concrete test analysis of the concrete compressive strength, splitting the variation of tensile strength, flexural strength, and economic aspects of performance, to provide a reference for further study of the straw fiber reinforced concrete and other performance and application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
