“…In the short term specific bioelectrochemical sensors will become more widespread and perform electrochemical bioassays for example to detect water born pathogens (Fritsch et al, 2008) and toxic algae (Diercks et al, 2008a), water quality assessment (Tonning et al, 2005) and general environmental monitoring (Marrazza et al, 1999). In the medium term, arrays of bioelectrochemical sensors could have applications in biochemical finger printing.…”

“…75 A tirosinase pode ser inibida por uma gama de poluentes, tais como carbamatos, organofosforados, ditiocarbamatos, atrazinas, tiuréas, ácidos carboxílicos aromáticos, triazinas, herbicidas, clorofenóis e agentes quelantes de cobre. [75][76][77][78][79][80][81][82][83][84][85][86] Desta forma, biossensores baseados em enzimas tirosinases podem ser empregados com biossensores baseados em inibição enzimática, detectando tanto o decrescimento da quantidade de oxigênio no meio reacional, quanto a formação da quinona, em presença do agente inibidor. Eletrodos de carbono, ouro, ouro modificado e eletrodos de Clark têm sido empregados na construção destes sensores.…”

Recebido em 3/5/07; aceito em 30/11/07; publicado na web em 4/9/08 BIOSENSORS BASED ON THE ENZYMATIC INHIBITION PROCESS. Fast, selective, reproducible and reliable detections have been carried out by using enzymatic biosensors in several areas. The enzymatic biosensors based on the inhibition represent an important role in analytical chemistry. Enzymes like cholinesterases, peroxidases, tyrosinases, etc. have been immobilized on electrochemical and optical transducers and the enzymatic activity decreasing in the presence of the inhibitor is related with its concentrations. This article presents a review on the enzymes used on the construction of these sensors, emphasizing the respective applications.

“…Although reports of SBP-based 163 biosensors are emerging, HRP biosensor research dominates and has continued to 164 develop through many forms, from the traditional voltammetric-and amperometric-165 based methods of detection, to nano-sized devices. Real time quantification of 166 hydrogen peroxide continues to be one of the main reasons for sensor development 167 [44], although other diverse applications include the detection of glucose [45], ethanol 168 [46] and tumour markers in vivo [47]. Enzyme-based biosensors require rapid and 169 uniform transfer of electrons generated at the enzyme active site to the transducer.…”

Horseradish and soybean peroxidases (HRP and SBP, respectively) are useful 9 biotechnological tools. HRP is often termed the classical plant heme peroxidase, and 10 although it has been studied for decades our understanding has deepened since its 11 cloning and subsequent expression, which has enabled numerous mutational and 12 protein engineering studies. SBP, however, has been neglected until recently; despite 13 offering a real alternative to HRP that actually outperforms it in terms of stability. 14 SBP is now used in numerous biotechnological applications, including biosensors. 15Review of both is timely. This article summarises and discusses the main insights into 16 the structure and mechanism of HRP, with special emphasis on HRP mutagenesis, and 17 outlines its use in a variety of applications. It also reviews current knowledge and 18 applications to date of SBP, particularly biosensors. The final paragraphs speculate on 19 the future of plant heme-based peroxidases, with probable trends outlined and 20 explored. 21 22
