The size reduction of chitosan derivatives improves their potential application in green organic synthesis due to the large surface area per unit mass and porous structure of the polymer. Chitosan-palladium composite was prepared from the reaction of chitosan with reduced PdCl2 salt solution. Modified chitosan-palladium nanoparticles were prepared by liquid atomization techniques. The physical properties of the airborne nanoparticles were studied using aerosol research methods, i.e., definition of geometric mean diameter, particle number concentration, and classification of particle distribution modes. The smallest chitosan-palladium nanoparticles (Dg = 15 ± 3 nm) were prepared by electrospray method. Chemical characterization of the chitosan-palladium nanoparticles deposited on the glass surface was performed using coherent anti-Stokes Raman scattering microscopy (CARS). The presence of an N–H vibrational signal at 3290 cm− 1 in the CARS spectrum proved to be a reliable and fast method for characterizing chitosan-structured nanoparticles. [ABSTRACT FROM AUTHOR] |
