Egg white coated alginate nanoparticles with electron sprayer for potential anticancer application

Abstract

To development biomimetic strategy for enhanced cancer therapy, the paclitaxel loaded egg white/sodium alginate nanoparticles were prepared by electronic spray method. Their appearance and particle size were observed by transmission electron microscope and particle size analyzer. The drug release behavior of nanoparticles was determined by high performance liquid chromatography (HPLC). The toxicity, morphology and interaction of nanoparticles to cells were studied by means of MTT, live/dead staining and laser scanning confocal microscopy. The results show that the nanoparticles have good particle size dispersion, regular morphology, good drug release performance, good biocompatibility and in vitro effective inhibition of CT26 colorectal cancer cells. These results demonstrated that the good biocompatibility of egg white coated sodium alginate nanoparticles and PTX loaded these nanoparticles would show potential application for cancer therapy.
