Preparation, Characterization and Evaluation of a Novel Drug Carrier for the Controlled Release of Curcumin

Abstract

The upsurge of cancer demands intense, rapid and effective intervention from the scientific society. Even though nanoparticles helped achieving this, maintaining its size without using toxic capping agents is challenging. Phytochemicals having reducing properties is a proper substitute and the efficiency of such nanoparticles could be further improved by grafting with suitable monomers. It could be further protected from rapid biodegradation by coating with suitable materials. This approach was utilized wherein, the green synthesized silver nanoparticles (AgNps) were initially functionalized with –COOH to couple with –NH₂ groups of ethylene diamine. It was then coated with polyethylene glycol (PEG) and hydrogen bonded with curcumin. The formed amide bonds could effectively uptake drug molecules and sensed environmental pH. Swelling studies and release profiles confirmed selective drug release. All these results along with those obtained from MTT assay, suggested the potential applicability of the prepared material in pH sensitive drug delivery of curcumin.
