Aim: Squid pens, a feather shaped structure in squid species, are waste material which are successfully utilized for the production of industrially important chitosan. The present study deals with characterization of squid pens extracted beta-chitosan coated magnetite nanoparticles    


Methodology: Beta-chitosan was extracted from squid pens. The extracted beta-chitosan was used as a surface amino coating polymer onto solvothermally prepared magnetite nanoparticles (MNs). Various characterization analysis was performed to understand the properties of MNs, chitosan and beta-chitosan coated MNs (βc-MNs).    


Results: Peak at 448 nm in UV-Spectrum corresponded the magnetite and required absorption peaks in IR spectrum showed perfect magnetite and chitosan formation. Also, electron micrographs revealed the flaky structure of chitosan, spherical structure of MNs and less aggregated structures of beta-chitosan coated MNs (βC-MNs). Diffraction pattern from X-ray diffraction (XRD) suggested the formation of MNs and βC-MNs and crystallite size (13.9 nm) was determined using Debye-Scherrer equation. Superparamagnetic behaviors of MNs were observed from the magnetization curve of vibrating sample magnetometer (VSM) plot.    


Interpretation: The characteristic studies revealed the extraction of beta-chitosan from squid pens and formation of MNs and βC-MNs.
