Abstract	We used sol-gel method for synthesizing nanoclusters of DyBa2Cu3O7-X high TC type II superconductor in presence of biopolymer chitosan. In the first stage, the precursor and biopolymer aggregated into amorphous matrix and hydrogels are then formed by thermogelling. The fibrous nature of the biopolymer chitosan is retained at high temperatures up to 500 °C. After heating to 900 °C, complete decomposition of BaCO3 and formation of the superconductor nanoparticles (with a diameter of 10-20 nm) occurred subsequently. Characterization of specimens was performed using scanning electron microscopy and transmission electron microscopy, supported by other techniques including XRD diffraction, energy dispersive X-ray, FT-IR spectrum and magnetic susceptibility measurements.
