Cellulose Beads Derived from Waste Textiles for Drug Delivery

Preparation and characterization of cellulose derived from rice husk for drug delivery

Cellulose has been the extracted from rice husk by chemical treatment with aqueous solution of sodium hydroxide. The physical properties of derived cellulose (water uptake and swelling behavior) has been investigated with view of different applications. The morphology and chemical structure were investigated by Infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM) and Thermogravimet...

Regenerated cellulose for controlled oral drug delivery

The performance of regenerated cellulose (RC) films and capsules was investigated for their applications in oral controlled drug delivery. Regenerated cellulose films were prepared by non-solvent-mediated, phase inversion of native and depolymerized cotton linter solutions (methylolcellulose; cellulose dissolved in dimethyl sulfoxide/ paraformaldehyde solvent system) in water as well as by phas...

Magnetic/pH-sensitive nanocomposite hydrogel based carboxymethyl cellulose –g- polyacrylamide/montmorillonite for colon targeted drug delivery

Objective(s): The main aim of current research was to develop a novel magnetically responsive hydrogel by radical polymerization of carboxymethyl cellulose (CMC) on acryl amide (Am) using N,N'-methylene bis acrylamide  (MBA)  as a crosslinking agent, potassium persulfate (KPS) as a free radical initiator, and  magnetic montmorillonite ( mMT)  nanoclay as nano-...

Phosphorous Containing Chitosan Beads for Controlled Oral Drug Delivery

Phosphorous containing chitosan (PCTS) was synthesized by a graft copolymerization technique in order to be used as controlled drug delivery devices. To test this potential, PCTS beads were prepared by using tripolyphosphate, at pH 4.0 and characterized by scanning electron microscopy. The in vitro drug release behavior in various pH solutions was studied using indomethacin (IM) as a model drug...
