“…Table 1 also compares the response of non‐enzymatic hydrogen peroxide sensors based on other hybrid materials. Among them, our sensor presents a very competitive performance with lower detection limit than most of them [36–38, 42–44, 48, 56–58], comparable to [39, 40, 45, 46, 50–52] and higher than [15, 41, 47, 53–55]. In general, the sensors that present better detection limits than our sensor, are built with several constituents that can make the preparation of the sensor more time consuming, like MWCNTs dispersed in avidin and Ru [15], GO, Fe 3 O 4 , PAMAM and Pd [41], Ag@Cu 2 O and N‐rGO [47], Pt nanoparticles and polyazure A [53], three‐dimensional CuO inverse opals coated with NiO nanoflowers [54] or Au and Ag nanoparticles in connection with a potential of −0.700 V [55].…”

We report a hybrid material obtained by dispersing the polyoxometalate n‐[Bu4‐N]2[Mo6O18NC13H9] functionalized with 2‐aminofluorene (POMAF) and multi‐walled carbon nanotubes (MWCNTs) in 1,3‐dioxolane (MWCNT‐ POMAF). We demonstrate the peroxidase‐like activity of the hybrid material and its application for the amperometric quantification of hydrogen peroxide at −0.450 V previous drop‐coating at glassy carbon electrodes, with a linear range between 1.0 μM and 6.0 μM and a detection limit of 330 nM. The reproducibility was 2.2 % using one MWCNTs‐POMAF dispersion, and 3.9 % using 4 different dispersions. The sensor was successfully used for the quantification of hydrogen peroxide in enriched milk samples.

Non-enzymatic electrochemical sensors possess superior stability and affordability in comparison to natural enzyme-based counterparts. A large variety of nanomaterials have been introduced as enzyme mimicking with appreciable sensitivity and detection limit for various analytes of which glucose and H2O2 have been mostly investigated. The nanomaterials made from noble metal, non-noble metal, and metal composites, as well as carbon and their derivatives in various architectures, have been extensively proposed over the past years. Three-dimensional (3D) transducers especially realized from the hybrids of carbon nanomaterials either with metal-based nanocatalysts or heteroatom dopants are favorable owing to low cost, good electrical conductivity, and stability. In this critical review, we evaluate the current strategies to create such nanomaterials to serve as non-enzymatic transducers. Laser writing has emerged as a powerful tool for the next generation of devices owing to their low cost and resultant remarkable performance that are highly attractive to non-enzymatic transducers. So far, only few works have been reported, but in the coming years, more and more research on this topic is foreseeable. Graphical abstract

“…It was made from commercial polymers such as polyimide (PI) derivatives in 2014 by exposing those to a computer-controlled CO 2 infrared laser which generates 3D graphene layers under ambient conditions [24]. This economic and reagent-free one-step synthesis of porous graphene on a polymer substrate opened incredible new applications for bioanalytical demands [21][22][23][25][26][27][28]. It was thus studied here as a material for sweat-based sensing.…”

Electrochemical multi-analyte point-of-care perspiration sensors using on-chip three-dimensional graphene electrodes

Multi-analyte sensing using exclusively laser-induced graphene (LIG)-based planar electrode systems was developed for sweat analysis. LIG provides 3D structures of graphene, can be manufactured easier than any other carbon electrode also on large scale, and in form of electrodes: hence, it is predestinated for affordable, wearable point-of-care sensors. Here, it is demonstrated that LIG facilitates all three electrochemical sensing strategies (voltammetry, potentiometry, impedance) in a multi-analyte system for sweat analysis. A potentiometric potassium-ion-selective electrode in combination with an electrodeposited Ag/AgCl reference electrode (RE) enabled the detection of potassium ions in the entire physiologically relevant range (1 to 500 mM) with a fast response time, unaffected by the presence of main interfering ions and sweat-collecting materials. A kidney-shaped interdigitated LIG electrode enabled the determination of the overall electrolyte concentration by electrochemical impedance spectroscopy at a fixed frequency. Enzyme-based strategies with amperometric detection share a common RE and were realized with Prussian blue as electron mediator and biocompatible chitosan for enzyme immobilization and protection of the electrode. Using glucose and lactate oxidases, lower limits of detection of 13.7 ± 0.5 μM for glucose and 28 ± 3 μM for lactate were obtained, respectively. The sensor showed a good performance at different pH, with sweat-collecting tissues, on a model skin system and furthermore in synthetic sweat as well as in artificial tear fluid. Response time for each analytical cycle totals 75 s, and hence allows a quasi-continuous and simultaneous monitoring of all analytes. This multi-analyte all-LIG system is therefore a practical, versatile, and most simple strategy for point-of-care applications and has the potential to outcompete standard screen-printed electrodes.
