“…Furthermore, the sensor was applied to measure the glucose levels in whole blood human, which was in good agreement with the commercial glucose monitoring system. The same goal was pursued by Timur's team who electrosynthesized the conducting polymer of 4‐(2,5‐di(thiophen‐2‐yl)‐1H‐pyrrol‐1‐yl) benzenamine (SNS‐NH 2 ) and modified it with AuNPs. They used AuNP‐SNS‐NH 2 as a platform for immobilization of GOx and used it for glucose detection in both batch and flow injection analysis (FIA) modes.…”

Among various immobilizing materials, conductive polymer-based nanocomposites have been widely applied to fabricate the biosensors, because of their outstanding properties such as excellent electrocatalytic activity, high conductivity, and strong adsorptive ability compared to conventional conductive polymers. Electrochemical biosensors have played a significant role in delivering the diagnostic information and therapy monitoring in a rapid, simple, and low cost portable device. This paper reviews the recent developments in conductive polymer-based nanocomposites and their applications in electrochemical biosensors. The article starts with a general and concise comparison between the properties of conducting polymers and conducting polymer nanocomposites. Next, the current applications of conductive polymer-based nanocomposites of some important conducting polymers such as PANI, PPy, and PEDOT in enzymatic and nonenzymatic electrochemical biosensors are overviewed. This review article covers an 8-year period beginning in 2010.

“…However, all of these methods suffer from either poor long-term stability or negative effects from being exposed to harsh reaction conditions [3]. Advances in nanotechnology offer an alternative for better immobilization by using nanomaterial such as nanoparticles, nanotubes, and fiber optics, which promote higher reliability and stability of the bioelements [7]. The transducer is another critical part of the microbial biosensor for converting the biological response to a measurable signal [1].…”

A microbial biosensor is an analytical device that immobilizes microorganisms onto a transducer for the detection of target analytes. With the development of nanotechnology, nanomaterials have been used to achieve better immobilization for developing a more reliable and selective microbial biosensor. Also, significant progress has been made in the development of transducer technology leading to higher sensitivity. Microbial biosensors have become one of the most useful means of monitoring environmental, food and clinical samples. In this review, we focus on the newly developed technologies and applications of microbial biosensors in recent years.

“…The thiol tail groups of an MPTS three-dimensional network is able to be covalently bound onto the surface of Au through cleavage of the S-H bond 17 and the formation of a Au-S bond, 18 while AuNPs can be conveniently self-assembled on the thiol groups present in the network. MPTS sol-gel and AuNPs-based materials have been used for the immobilization of enzymes, such as dehydrogenase, 17,19 bilirubin oxidase, 20 lactate oxidase 21 and glucose oxidase, 22 for the development of biosensors. However, to the best of our present knowledge, a tyrosinasebased biosensor fabricated by AuNPs and sol-gel film has not been reported.…”
