Cryoscopic study of aqueous solutions of sulfur-containing amino acids adducts of fullerene C<sub>60</sub>
The study presents cryoscopic investigation of binary systems containing adducts of fullerene C<sub>60</sub> with sulfur-containing amino acids C<sub>60</sub>(C<sub>3</sub>H<sub>7</sub>NO<sub>2</sub>S)<sub>3</sub> (adduct with L-cysteine, C<sub>60</sub>-Cys) and C<sub>60</sub>(C<sub>5</sub>H<sub>11</sub>NO<sub>2</sub>S)<sub>3</sub> (adduct with L-methionine, C<sub>60</sub>-Met). Excess thermodynamic functions of solution components were calculated using a semi-empirical model Virial Decomposition Asymmetric Model (VD-AS). Adducts of fullerene C<sub>60</sub> with sulfur-containing amino acids were characterized using <sup>13</sup>C NMR, IR and UV/Vis spectroscopy, elemental analysis, and HPLC. Additionally, experimental data on the enthalpy of combustion of fullerene adducts, as well as concentration dependences of particle size distribution and ζ-potentials are presented.
