Bioactive glass nanoparticles (BG-NPs), based on both ternary (SiO(2)-CaO-P(2)O(5)) and binary (SiO(2)-CaO) systems, were prepared via an optimized sol-gel method. The pH of preparation and the effect of heat treatment temperature were evaluated, as well as the effect of suppressing P in the bioactivity ability of the materials. The morphology and composition of the BG-NPs were studied using FT...

Encapsulation techniques are fmding increasing interest in a variety of areas of biotechnology. Enzymes, living ceils, hormones, drugs, adsorbents and other bioactive materials can be encapsulated and used in bioreactors, artificial organs, controlled drug-release systems, bioseparation systems and etc (Chang, 1972; Kondo, 1979; Lira, 1984; Nigam, 1988; Nixon, 1976). Ideally, encapsulation of b...

Cellulose nanofi brils (CNF), also known as nanofi brillar cellulose (NFC), are an advanced biomaterial made mainly from renewable forest and agricultural resources that have demonstrated exceptional performance in composites. In addition, they have been utilized in barrier coatings, food, transparent fl exible fi lms and other applications. Research on CNF has advanced rapidly over the last de...

AIM Computational design of and systematic search for a new type of molecular scaffolds termed analog series-based scaffolds. MATERIALS & METHODS From currently available bioactive compounds, analog series were systematically extracted, key compounds identified and new scaffolds isolated from them. RESULTS Using our computational approach, more than 12,000 scaffolds were extracted from bioa...
