Size characterization of biopolymer-based nanocomposite using dynamiclight scattering (DLS) technique

Properties of matter at nanoscale can uniquely be described in terms of engineering, science, andtechnology principles. Biopolymer-based nanocomposites have several advantages that make use ofthese nanomaterials compatible in different areas, especially in drug delivery systems. Chitosan,sodium alginate, and pectin biopolymers were used in the present study where the identification ofthe resultant nanocomposites was carried out in terms of size measurements using dynamic lightscattering (DLS) technique which is based on performance laser beam as a monochromatic source oflight, interacts with the particle(s) in the test solution. The particle size according to the cumulantanalysis was about ۴۷۱ nm. While size measurements of the composite with use of Pade-Laplace andSparse Bayesian learning (SBL) algorithms, resulted particle with ۵۱ nm and ۶۹ nm, respectively
