“…Since Neff firstly reported the electrochemical behavior of PB and the successful deposition of a thin layer of PB on a platinum foil in 1978 [ 74 ], the wide application of PB has been promoted in various construction of electrochemical immunosensing interface, especially for its development in multiplexed electrochemical immunoassay [ 75 , 76 ]. Moreover, for the modification ways of PB on an electrode surface, there are two main sorts of common methods, including post-modification [ 77 , 78 ] and in-situ preparation [ 79 , 80 ], and both of them can generate the legible signal peaks. For example, Lai and coworkers reported on an ultrasensitive multiplexed electrochemical immunosensing interface to simultaneously detect CEA and AFP [ 81 ].…”

Appropriate labeling method of signal substance is necessary for the construction of multiplexed electrochemical immunosensing interface to enhance the specificity for the diagnosis of cancer. So far, various electrochemical substances, including organic molecules, metal ions, metal nanoparticles, Prussian blue, and other methods for an electrochemical signal generation have been successfully applied in multiplexed biosensor designing. However, few works have been reported on the summary of electrochemical signal substance applied in constructing multiplexed immunosensing interface. Herein, according to the classification of labeled electrochemical signal substance, this review has summarized the recent state-of-art development for the designing of electrochemical immunosensing interface for simultaneous detection of multiple tumor markers. After that, the conclusion and prospects for future applications of electrochemical signal substances in multiplexed immunosensors are also discussed. The current review can provide a comprehensive summary of signal substance selection for workers researched in electrochemical sensors, and further, make contributions for the designing of multiplexed electrochemical immunosensing interface with well signal.

“…The development of electrochemical sensors has been promoted by the extensive use of carbonaceous nanostructured materials [ 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Graphene is known for its high surface area, rapid electron mobility, excellent conductivity, and mechanical stability [ 21 , 22 , 23 , 24 , 25 ].…”

A 3D porous graphene structure was directly induced by CO2 laser from the surface of Kapton tape (carbon source) supported by polyethylene terephthalate (PET) laminating film. A highly flexible laser-induced porous graphene (LI-PGr) electrode was then fabricated via a facile one-step method without reagent and solvent in a procedure that required no stencil mask. The method makes pattern design easy, and production cost-effective and scalable. We investigated the performance of the LI-PGr electrode for the detection of methamphetamine (MA) on household surfaces and in biological fluids. The material properties and morphology of LI-PGr were analysed by scanning electron microscopy (SEM), energy dispersive x-ray (EDX) and Raman spectroscopy. The LI-PGr electrode was used as the detector in a portable electrochemical sensor, which exhibited a linear range from 1.00 to 30.0 µg mL−1 and a detection limit of 0.31 µg mL−1. Reproducibility was good (relative standard deviation of 2.50% at 10.0 µg mL−1; n = 10) and anti-interference was excellent. The sensor showed good precision and successfully determined MA on household surfaces and in saliva samples.

“…Di-imine is not stable and hydrated two times to form imine-alcohol and uric acid-4,5-diol. At pH 5, this compound is decomposed to allantoin and carbon dioxide (Soleh, Kanatharana, & Thavarungkul, 2019). Therefore, uric acid can be analyzed using electrochemical sensor with the voltametric method.…”

“…The sensitivity and selectivity of electrode can be increased by adding conductive material to modified the working electrode. Modification of glassy carbon electrode (GCE) that had been done were with graphene oxide (Soleh et al, 2019), poly(3,4ethylenedioxythiophene)/reduced graphene oxide electrode (Tukimin et al, 2017), N,Co-doped porous carbon (Liu, Liu, Wang, & Ye, 2019), and molecularly imprinted polymer (Zheng et al, 2018).…”

Arrowroot starch membrane-modified glassy carbon electrode were constructed for the determination of uric acid. The membrane consist of arrowroot starch, polyvinyl alcohol, uric acid, and crosslinker. The crosslinker used was sodium tripolyphosphate, citric acid, and glutaraldehyde. Carbon material was added to increase the sensitivity. The composition of membrane influences the electrodes sensitivity. The best composition of arrowroot starch membrane is UA1 using 0.1% uric acid in membrane and STPP as crosslinker. The linearity concentration, sensitivity, and detection limit were 100-500 µM, 0.0509 A/M and 76 µM, respectively.
