“…27 This kind of evaluation considering the target compound has been performed for calcein, 28 gallic acid, 29 nicotine, 30 and magnolol. 31 Particularly, the interaction of CIP with DNA has been evaluated using mercury, 32 GC, 12,33 and MWCNT/GC electrodes. 34 To the best of our knowledge, the use of a BDD electrode to monitor the interaction between CIP and dsDNA has never been reported.…”

“…[27][28][29][30][31] Recently, interactions of magnolol with DNA have been studied by electrochemical and spectral methods. 32 Considering the wide interest in naturally occurring compounds as starting monomers to prepare new thin films with improved biosensor properties and acceptable metabolic profiles, we selected some phenols belonging to natural 2-methoxyphenols and hydroxylated biphenyls for further study. In this work the permselectivity and stability of eugenol, isoeugenol, dehydrodieugenol (a natural C 2 -symmetric dimer of eugenol) and magnolol in the detection of H 2 O 2 were evaluated upon electropolymerization by cyclic voltammetry (CV) and constant potential amperometry (CPA) on a Pt/Ir electrode.…”

Amperometric biosensors are often coated with a polymeric permselective film to avoid electroactive interference by reducing agents present in the target medium. Phenylenediamine and phenol monomers are commonly used to form these permselective films in the design of microsensors and biosensors. This paper aims to evaluate the permselectivity, stability and lifetime of polymers electrosynthesized using either constant potential amperometry (CPA) or cyclic voltammetry (CV) from naturally occurring phenylpropanoids in monomeric and dimeric forms (eugenol, isoeugenol, dehydrodieugenol and magnolol). Sensors were characterized by scanning electron microscopy and permselectivity analysis. Magnolol formed an electro-deposited polymer with a more defined three-dimensional texture in comparison with the other films. The phenol-derived films showed different permselectivity towards H2O2 over ascorbic acid and dopamine, likely to be related to the thickness and compactness of the polymer. The CV-derived films had a better permselectivity compared to the CPA-corresponding polymers. Based on these results, the permselectivity, stability and lifetime of a biosensor for glucose were studied when a magnolol coating was electro-deposited. The structural principles governing the permselectivity of the magnolol-derived film are suggested to be mainly related to the conformational flexibility of this monomer. Newly designed biosensors, coated with electropolymerized natural phenol derivatives, may represent promising analytical devices for different application fields.

“…The electrochemical behaviors of magnolol and its interaction with DNA were studied at glassy carbon electrode (GCE) by Zhou et al. 13. The amplification effect of functionalized gold nanoparticles on the binding of anticancer drug dacarbazine to DNA was investigated using GCE and cyclic voltammetry (CV) technique by Shen et al.…”

The electrochemical investigation of the interaction between the anticancer drug mitomycin C (MC) and DNA was described using a single-walled carbon nanotube (SWCNT)/poly(vinylferrocenium) (PVF + ) modified pencil graphite electrode (PGE). The electrochemical oxidation signals of guanine were monitored before and after the interaction between MC and DNA by using differential pulse voltammetry. The effects of DNA and MC concentration and MC interaction time were examined based on the electrode response. Cyclic voltammetry and electrochemical impedance spectroscopy were used for the characterization of SWCNT/PVF + modified and PVF + modified PGEs. The detection limit corresponded to 625 ng/mL for MC using calf thymus double-stranded DNA immobilized SWCNT/PVF + modified PGE.
