New electrochemical laccase-based biosensor for dihydroxybenzene isomers determination in real water samples

Effect of Modification of a Laccase-Based Electrochemical Biosensor with Carbon Nanotubes on Signal Separation of Dihydroxybenzene Isomers

“…During the deposition of the receptor layer and biosensor construction, the biological precursor is introduced inside the plasma stream, where it is cross-linked/polymerized and then deposited on the GCE surface. The conducted electrochemical studies have clearly confirmed that appropriate optimization of plasma and process parameters allows the construction of laccase-based biosensors with similar or better analytical parameters compared to biosensors obtained by conventional methods. − …”

“…Laccase biosensors containing an interlayer of CNTs exhibit significantly better analytical performance in the quantification of both rutin 27 and dopamine. 21 Our previous study presented in the work 20 indicated that the laccase biosensors obtained by the innovative SPP technique could not be used for the simultaneous quantification of all three dihydroxybenzene isomers due to the overlapping analytical signals for CT and HQ. The scientific literature indicates that such analytical problems can be successfully overcome by using intermediate layers of carbon nanomaterials in the biosensor design.…”

D‐A‐D type functional conducting polymer: Development of its electrochromic properties and laccase biosensor

“…Highly toxic phenolic compounds are come from pesticides, dyes and pharmaceuticals and these types of compounds inflict both severe and long‐lasting effects on both humans and animals 1,2 . One of the phenolic compounds family, catechol act as carcinogens and causes damage to the red blood cells and the liver 3 . Thus, their quantitative detection is significant to develop a facile and low‐cost method.…”

Fabrication of D–A–D type conducting polymer, carbon nanotubes and silica nanoparticle-based laccase biosensor for catechol detection

“…[4][5][6] In literature, different laccase-based electrochemical biosensors have been developed for catechol determination using different sensor architectures. 2,3,[7][8][9][10] Conducting polymers (CPs) have been recognized as excellent materials that offer a variety of advantages for designing electrochemical biosensors with proper functionalization. In this regard, our group has previously reported on a catechol sensor based on CPs functionalized with different moieties, which is capable of providing a good microenvironment for enzyme molecules and good conductivity with their donor-acceptor type structures.…”
