Poly(butyl cyanoacrylate), Nanoparticle, Doxorubicin, Polymerization, Drug entrapment, Drug releaseAbstract
Poly(butyl cyanoacrylate) nanoparticles were synthesized by dispersion polymerization and characterized by 1H-NMRspectroscopy, differential scanning calorimetry and transmission electron microscopy. Particle properties such as zetapotential and size, and the influence of concentration and type of stabilizer on particle size were studied. The influenceof polymerization factors such as monomer concentration, polymerization time and temperature on the particle size anddistribution, and their effect on entrapment efficiency of the nanoparticles was studied, using doxorubicin hydrochloride(DH) as a model drug. High monomer concentrations lead to the formation of larger particles with broad and bimodalsize distribution, and increased the drug entrapment. Polymerization at low temperatures resulted in smaller particles,and agglomeration was found at high temperature (60°C), with reduced drug entrapment. High polymerization times didnot show much influence on particle size, but increased the drug entrapment. Drug loading into nanoparticles was carried out by incorporation and adsorption techniques, and drug entrapment was determined. The nanoparticles loadedby incorporation and adsorption techniques showed rapid drug release in 0.001N HCl. Drug release from both types ofnanoparticles followed Higuchi equation. An attempt was also made to critically correlate the particle properties anddrug release behavior and emphasize its importance in various facets of drug delivery.Downloads
