摘要: In this work the preparation of chitosan nanoparticle was investigated using methacrylic acid in different conditions and studied by particle size analyzer, zeta-potential, Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance (NMR) transmission electron microscopy (TEM). The dependent on concentration used during method. Nanoparticles with sizes as small 60 nm were achieved, that can be extremely important for several applications. nanoparticles solution also pH-sensitive, due to swelling aggregation nanoparticles. obtained presented a very homogeneous morphology showing quite uniform particles distribution rather spherical shape.
