Optimized Preparation of Carboxymethyl Chitosan/Sodium Alginate Hemostatic Microcapsule

Preparation and biosorption evaluation of Bacillus subtilis/alginate–chitosan microcapsule

The aim of this study was to assess the effect of alginate-chitosan microcapsule on viability characteristics of Bacillus subtilis and the ability of B. subtilis/alginate-chitosan microcapsule to remove uranium ion from aqueous solution. The effects of particle size, chitosan molecular weight and inoculum density on viability characteristics were studied using alginate-chitosan microcapsule-imm...

3D Printability of Alginate-Carboxymethyl Cellulose Hydrogel

Three-dimensional (3D) bio-printing is a revolutionary technology to reproduce a 3D functional living tissue scaffold in-vitro through controlled layer-by-layer deposition of biomaterials along with high precision positioning of cells. Due to its bio-compatibility, natural hydrogels are commonly considered as the scaffold material. However, the mechanical integrity of a hydrogel material, espec...

Preparation of Copper-loaded Microcapsule Formulations

Carboxymethyl starch/alginate microspheres containing diamine oxidase for intestinal targeting

The association of carboxymethyl starch (CMS) and alginate is proposed as a novel matrix for the entrapment of bioactive agents in microspheres affording their protection against gastrointestinal degradation. In this study, the enzyme diamine oxidase (DAO) from white pea (Lathyrus sativus) was immobilized by inclusion in microspheres formed by ionotropic gelation of CMS/alginate by complexation...

Optimized preparation and evaluation of 99mTc-Streptomycin

Introduction: The endemic occurrence of new strains of tuberculosis around the globe has initiated new research on developing diagnostic radiopharmaceutical based on antibiotics. Methods:Tc-99m labeled streptomycin was prepared using freshly milked 99mTcO4- and various concentrations of streptomycin, stannous chloride at various temperatures in high yield radio...
