“…Sensitivity corresponding to the linear range for catechol was 51.58 mA mM -1 , which is higher than that obtained on Horseradish peroxidase biosensor and tyrosinase biosensors-modified electrodes. [35][36][37] Moreover, the detection limit of catechol was found to be about 1.4 mM according to the formula 3s b /m criteria, which is lower than that obtained in previous report, 38,39 demonstrating that Au/TiO 2 -BDD3 electrode is a better choice for catechol detection.…”

Au/TiO 2 nanorod composites with different ratios of [TiO 2 ]: [Au] have been prepared by chemically reducing AuCl 4 -on the positively charged TiO 2 nanorods surface and used to modify boron-doped diamond (BDD) electrodes. The electrochemical behaviors of catechol on the bare and different Au/TiO 2 nanorod composites-modified BDD electrodes are studied. The cyclic voltammetric results indicate that these different Au/TiO 2 nanorod composites-modified BDD electrodes can enhance the electrocatalytic activity toward catechol detection, as compared with the bare BDD electrode. Among these different conditions, the Au/TiO 2 -BDD3 electrode (the ratio of [TiO 2 ]:[Au] is 27:1) is the most choice for catechol detection. The electrochemical response dependences of the Au/TiO 2 -BDD3 electrode on pH of solution and the applied potential are studied. The detection limit of catechol is found to be about 1.4 × 10 -6 M in a linear range from 5 × 10 -6 M to 200 × 10 -6 M on the Au/TiO 2 -BDD3 electrode.

“…Furthermore, sensing based on fluorescence is usually highly efficient. Detecting of phenolic compounds is mostly electrochemical process (S. Yang et al, 2006;Shan et al, 2003;Serra et al, 2003), rarely UV absorption (Cabaj et al, 2010a;Cabaj et al, 2010b).…”

“…Electrodes modified with these enzymes have the advantage that the detection of phenolic compounds can be carried out between -0.2 and 0.05 V versus SCE and the interface is minimized. The mechanism for tyrosinase, laccase and peroxidase in the electrochemical biosensors is different (S. Yang et al, 2006).…”

“…The following discussion about the bioelectrochemistry of peroxidases is directed for a more detailed presentation of the electrochemical reactions of peroxidase providing the basis for amperometric peroxidase-modified electrodes. Horseradish peroxidase based biosensors are most sensitive for a great number of phenolic compounds since phenols can be act as electron donors for peroxidase (S. Yang et al, 2006).…”

“…17 In this sense, a wide variety of compounds have been used as electron transfer mediators for electrooxidation or reduction of several target molecules. [17][18][19][20] The modification of electrodes with alternating deposition of functional compounds has been attracting much interest because of its potential application, [21][22] and it is a very simple way to experimentally produce complex layered structures with precise control of layer composition and thickness. 23 Additionally, porphyrins and metalloporphyrins have demonstrated good features as analytical sensors because they can provoke electrocatalysis, increasing the sensitivity and selectivity of the electrode.…”

Descreve-se, no presente trabalho, o desenvolvimento de um sensor voltamétrico altamente sensível para a oncocalixona A, utilizando-se eletrodo de carbono vítreo modificado com uma bicamada de ftalocianina tetrassulfonada de ferro(II) (FeTSPc) e tetra-(N-metil-4-piridil)-porfirina de ferro(III) (FeT 4 MPyP). O eletrodo modificado apresentou alta atividade catalítica e estabilidade em relação à redução da oncocalixona, proporcionando deslocamento anódico de ca. de 30 mV e amplificação da corrente de pico, em relação a iguais parâmetros obtidos em eletrodo de carbono vítreo não modificado. Um ampla faixa linear de resposta entre 0.005-1.2 µmol L -1 , com sensibilidade de 8.11 µA L µmol -1 e limites de detecção (LOD) e quantificação (LOQ) de 1.5 e 5 nmol L -1 foram obtidos, com o uso desse sensor.The development of a highly sensitive voltammetric sensor for oncocalyxone A using a glassy carbon electrode modified with a bilayer iron(II) tetrasulfonated phthalocyanine (FeTSPc) and iron(III) tetra-(N-methyl-4-pyridyl)-porphyrin (FeT 4 MPyP) is described. The modified electrode showed high catalytic activity and stability for the oncocalyxone A reduction, provoking the anodic shift of the reduction peak potentials of ca. 30 mV and presenting much higher peak currents than those obtained on the bare GC electrode. A wide linear response range between 0.005-1.2 µmol L -1 , with a sensitivity of 8.11 µA L µmol -1 and limits of detection (LOD) and quantification (LOQ) of 1.5 and 5 nmol L -1 were obtained with this sensor.Keywords: voltammetric sensor, oncocalyxone, quinone, chemically modified electrodes, catalysis IntroductionPlants are repositories for bioactive organic molecules. Several classes of natural compounds are pharmacologically active ingredients and serve as drugs and/or leads for drug developments. Among them, quinones, ubiquitous secondary metabolites, play essential roles, mainly in the biochemistry of energy production, serving as vital links in the electron transport. 1 They form an important class of toxic metabolites and paradoxically, can be either, potentially carcinogenic or effective anticancer agents. The cytotoxic activity of quinones can often be correlated to their chemical behavior. The striking feature of quinone chemistry is the ease reduction and therefore their ability to act as oxidizing or dehydrogenating agents, the driving force being the formation of a fully aromatic system. [2][3][4][5] Auxemma oncocalyx Taub. is a native Brazilian tree, characteristic of the xerophytic vegetation present in the northeastern region. It is commonly called "pau branco." The chemical investigation of A. oncocalyx heartwood extracts resulted in the isolation and characterization of several unusual terpenoid quinones and hydroquinones of C 16 framework. 6-9 These secondary metabolites seem to be typical of the genus and, interestingly, were isolated in a homolog series differing in their degree of oxidation, oxygenation (ether or alcohol), rearrangement and intramolecular cyclization of the terpenoid side ...
