Surface| Summary: | Comparative investigations of low-temperature processes of dipolar relaxation in frozen aqueous dispersions of nanooxides alone and with the presence of bovine serum albumin (BSA) were carried out using thermally stimulated depolarization current method. For the later systems, an increase in contribution of relaxational processes is observed at T> 160-170 K, since for aqueous suspensions of nanooxides, greater TSD currents are observed at T < 160-170 K This difference is due to the participation of the BSA molecules (polar bonds, groups, fragments, whole molecules) in the relaxation processes, whose features depend also on the nature of nanooxide and a character of BSA |
