Removal of heavy metal ions (Pb, Cu, Cr, and Cd) from multimetal simulated wastewater using 3-aminopropyl triethoxysilane grafted agar porous cryogel.

In this study, we have developed agar, a seaweed derived polysaccharide based green adsorbent for the removal of heavy metal ions (Pb, Cu, Cr and Cd) from multimetal solution. Porous cryogels of agar grafted with 3-aminopropyl triethoxysilane (APTES) were prepared by freeze-drying. The adsorption capacity and selectivity of the optimized APTES-agar cryogel for heavy metal ions (Cu, Cr, Pb, Cd) were investigated in multimetal solutions.

Multifunctional 58S Bioactive Glass/Silver/Cerium Oxide-Based Biocomposites with Effective Antibacterial, Cytocompatibility, and Mechanical Properties.

58S bioactive glass (BG) has effective biocompatibility and bioresorbable properties for bone tissue engineering; however, it has limitations regarding antibacterial, antioxidant, and mechanical properties. Therefore, we have developed BG biocomposites by reinforcing 58S BG with silver and ceria nanoparticles, which showed effective bactericidal properties by forming inhibited zones of 2.13 mm (against ) and 1.

Preparation and assessment of agar/TEMPO-oxidized bacterial cellulose cryogels for hemostatic applications.

In this work, we have demonstrated agar and oxidized bacterial cellulose cryogels as a potential hemostatic dressing material. TEMPO-oxidized bacterial cellulose (OBC) was incorporated into the agar matrix, improving its mechanical and hemostatic properties. The oxidation of bacterial cellulose (BC) was evidenced by chemical characterization studies, confirming the presence of carboxyl groups.
