Fully bioresorbable polymer matrix composites have long been considered as potential orthopaedic implant materials, however their combination of mechanical strength, stiffness, ductility and bioresorbability is also attractive for cardiac stent applications. This work investigated reinforcement polylactide-based polymers with phosphate glasses, addressing key drawbacks current stents, examined ...

Calcium carbonate-based bone substitutes derived from natural coral exoskeleton (aragonite) are resorbed and remodeled faster than calcium phosphate-based substitutes. However, species with structures appropriate for use as very limited. Therefore, it is important to evaluate potential of artificial carbonate ceramics a substitute. In this study, granules various porosities pore sizes were prep...

Abstract Ubiquitous use of electronic devices has led to an unprecedented increase in related waste as well the worldwide depletion reserves key chemical elements required their manufacturing. The biodegradable and abundant organic (carbon-based) materials can contribute alleviate environmental impact industry. pigment eumelanin is a bio-sourced candidate for environmentally benign (green) elec...

The healing process after implantation of sintered bone in the rat parietal bone was compared with that of synthetic hydroxyapatite using both scanning electron and light microscopy. The results showed that the differences between the sintered natural bone and the synthetic hydroxyapatite implantations were in the states of bone union and the bioresorbability of the implanted materials, even th...

The adverse effects of stress shielding from the use of high-modulus metallic alloy bio-implant materials has led to increased research into developing polymer-ceramic composite materials that match the elastic modulus of human bone. Of particular interest are poly-l-lactic acid- hydroxyapatite (PLA/HA)-based composites which are fully resorbable in vivo. However, their bioresorbability has a d...

Polylactides are commonly praised for their excellent mechanical properties (e.g. a high modulus and yield strength). In combination with their bioresorbability and biocompatibility, they are considered prime candidates for application in load-bearing biomedical implants. Unfortunately, however, their long-term performance under static load is far from impressive. In a previous in vivo study on...

Apatite-polymer composites mimicking specific structure of natural bone are promised as bone substitutes with moderate flexibility able to be fabricated into desired shapes as well as bone-bonding bioactivity. In order to precipitate the apatite on polymer surfaces, aqueous processing using solution supersaturated to the apatite has been attracting as much attention. Polyglutamic acid (PGA) is ...

Tissue engineering (TE) is the approach to combine cells with scaffold materials and appropriate growth factors regenerate or replace damaged degenerated tissue organs. The material as a template for formation plays most important role in TE. Among materials, silk fibroin (SF), natural protein outstanding mechanical properties, biodegradability, biocompatibility, bioresorbability has attracted ...

Biosilicate® glass-ceramics are among the most valid alternatives to 45S5 Bioglass. They combine a similar bioactivity and bioresorbability as with superior mechanical strength, owing crystallization of Na–Ca silicate phase. This may be experienced upon viscous flow sintering fine glass powders, thus configuring sinter-crystallization process. As is seldom complete, can also applied semicrystal...
