摘要:
Electrochemical investigation of the interaction between titanocene dichloride and several biomolecules, i.e., human and bovine serum albumin (HSA and BSA), and single-strand and double-strand deoxyribonucleic acid (ss- and ds-DNA) is reported. The addition of biomolecules to a hydroalcoholic solution of TiCp2Cl2 was followed by a decrease in the Ti(IV)/Ti(III) reduction peak current, due to the formation of adducts with lower diffusion coefficients. Qualitative analysis of the data reveals that titanocene dichloride has a higher affinity for proteins than for nucleic acids. (C) 2008 Elsevier B.V. All rights reserved.
