One-step synthesis of polyethylene microspheres using a modified chemical route for pulmonary drug delivery

Polyethylene microspheres (microparticles) were prepared using a modified chemical route. The prepared powder samples were characterized using scanning electron microscopy, Fourier transform infrared spectroscopy and differential scanning calorimetry. The scanning electron microscopy images show that the concentration of polyglycolic acid decreased the agglomeration and increased the degree of sphericity of the polyethylene microspheres. The results show that the polyethylene microparticles may be good candidates as drug carriers for pulmonary drug delivery.
