“…1c. Details on the electronic instrumentation are given elsewhere [13]. The working electrode potential was set at -280 mV and the resulting current was recorded during 60 s; this potential value is negative enough to produce the reduction of 1,4 benzoquinone under diffusion-controlled conditions [14].…”

An amperometric biosensor for the quantification of food allergens based on an inhibitory immunoassay is presented. As a proof of concept, the experimental conditions were optimized for the detection of β-casein in the 0-10 ppm range. Eight electrochemical cells were integrated into a small-sized portable potentiostat controlled by a smartphone via Bluetooth communication. The determination of β-casein in eight different samples can be measured with the electrochemical biosensor, which has the potential to be modified for the detection of multiple allergens.

“…Electrochemical measurements were carried out at 25 °C in 50 μL of a PBS buffer of pH 7, 0.1 M KCl, 4 mM hydroquinone (redox mediator), and 1.5 mM H 2 O 2 . A portable potentiostat Nanopoc [17] was used for the amperometric measurements (Figure 1c). Potentials were measured and referred to in the text against a Ag|AgCl|0.1 M KCl reference electrode.…”

In this article, we introduce the use of a carboxy-functionalized waterborne carbon nanotube ink for the fabrication of an amperometric biosensor aimed at the quantification of β-lactoglobulin. Detection of this protein from cow’s milk was performed by a sandwich immunoassay onto printed carbon nanotube electrodes. The electrodes were printed using a carbon nanotube ink modified with polystyrene beads containing a high amount of carboxylic groups for protein immobilization. This strategy showed enhanced sensing performance compared to the use of oxidative treatments for the functionalization of electrodes. These electrodes showed an excellent electrochemical behavior, and proteins could be immobilized on their surface via the carbodiimide reaction. These antibody-immobilized carbon nanotube electrodes allowed for the detection of β-lactoglobulin in sub-ppm concentrations.

“…Sun et al tried two different potentiostat sets to optimize the smartphone-based CV measurements with three electrodes . Then, Salomon et al reported a multichannel amperometric platform, which provided a high-throughput screening method for serologic diagnosis of infectious diseases (Salomon et al, 2014).…”
