“…43−46 Despite the well-understood catalytic reactions and ultra-high sensitivity, fabrication of many of such functional nickel oxide-based nanostructures often require complex chemical synthesis and lengthy and costly cleanroom fabrication processes. 47 While recent advancements in printed electronics and additive manufacturing technologies have provided a new paradigm in scalable manufacturing of many of such glucose sensors, the desired functional material for printing still needs to be prepared in the form of inks and pastes made of suspended nano-and microparticles. The synthesis of these materials often relies on time-consuming chemical synthesis processes including solvothermal/hydrothermal processes, 41,42 sol−gel, 48 chemical bath deposition, 49 chemical 50 and physical 51,52 vapor deposition, electrochemical deposition, 53 microwave-assisted approaches, 54 and electrospinning.…”

In this paper, we present a novel laser-induced oxidation procedure for in situ formation of nickel oxide nanoporous structures directly onto the nickel surface as a highly sensitive nonenzymatic glucose sensor. The formation of mesoporous nickel oxide is confirmed by field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray diffraction. Electrochemical properties of the pristine and laser-induced oxidized nickel (LIO-Ni) films were studied using cyclic voltammetry and electrochemical impedance spectroscopy. The unique three-dimensional mesoporous architecture of the oxide film on the LIO-Ni electrode resulted in a dramatic enhancement in electrochemical reduction/oxidation performance with a 10-fold increase in electrocatalytic activity for nonenzymatic glucose oxidation as compared to the pristine-Ni electrode. The LIO-Ni biosensor performance was successfully examined for the amperometric detection of glucose over a wide concentration range from 5 μM to 1.1 mM with a high linear sensitivity of 5222 μA mM −1 cm −2 . The limit of detection was obtained as low as 3.31 μM with a signal-tonoise ratio of 3. Furthermore, the LIO-Ni electrode showed outstanding long-term stability, reproducibility, and high selectivity in the presence of various interfering agents including uric acid, L-ascorbic acid, acetaminophen, glutamic acid, and citric acid. The demonstrated laser-induced oxidation process can be potentially adapted to the scalable manufacturing of a wide range of other easyto-use and robust metal oxide-based sensors for nonenzymatic biosensing applications.

“…The formation of silver phosphate, Ag 3 PO 4 , was monitored for phosphate ion detection, with the nozzlejet-printed, silver/reduced, graphene oxide (Ag/rGO) composite-based ISFET sensor reported in [82]. In [83] a nickel oxide/oxyhydroxide-modified printed carbon electrode was employed for chrono-potentiometric assessment of nickel phosphate (NiPO4) produced as a result of first Ni(II)O oxidation to Ni(III)OOH in alkaline media. As a result of further Ni(III)OOH interaction with H 2 PO 4 − , it was possible to detect the latter by means of indirect procedure.…”

The continuously rising interest in chemical sensors’ applications in environmental monitoring, for soil analysis in particular, is owed to the sufficient sensitivity and selectivity of these analytical devices, their low costs, their simple measurement setups, and the possibility to perform online and in-field analyses with them. In this review the recent advances in chemical sensors for soil analysis are summarized. The working principles of chemical sensors involved in soil analysis; their benefits and drawbacks; and select applications of both the single selective sensors and multisensor systems for assessments of main plant nutrition components, pollutants, and other important soil parameters (pH, moisture content, salinity, exhaled gases, etc.) of the past two decades with a focus on the last 5 years (from 2017 to 2021) are overviewed.

“…A paper-based screen-printed EC sensor working on the similar mechanism as described by 23 and 24 was developed where the electroactive area was modified with 100 mM molybdate ions, 100 mM KCl (supporting electrolyte) and 100 mM sulfuric acid, and the formation of phosphomolybdic complex in the presence of phophate ions [108]. Alternatively, a solid state sensor using nickel oxideoxyhydroxide-modified printed carbon electrode for potentiometric phosphate detection was developed, where in alkaline media and in the presence of hydroxide groups, NiO (Ni(II)) is oxidized to NiOOH (Ni(III)) as an intrinsic redox processes, and in the presence of phosphate, NiOOH reacts with H 2 PO − 4 to produce nickel phosphate (NiPO 4 ) characterized using chrono-potentiometry [103]. Sensitivity of the developed sensor was examined towards the following interfering ions: A nozzle-jet printed silver/reduced graphene oxide (Ag/rGO) composite-based ISFET sensor on a flexible disposable polymer platform was presented where the mechanism of the phosphate ion detection was elucidated as [104],…”

Development and deployment of sensing technologies is one of the main steps in achieving sustainability in crop production through precision agriculture. Key sensing methodologies developed for monitoring soil moisture and nutrients with recent advances in the sensing devices reported in literature using those techniques are overviewed in this article. The soil moisture determination has been divided into four main sections describing soil moisture measurement metrics and laboratory-based testing, followed by in-situ, remote and proximal sensing techniques. The application, advantages and limitations for each of the mentioned technologies are discussed. The nutrient monitoring methods are reviewed beginning with laboratory-based methods, ion-selective membrane based sensors, bio-sensors, spectroscopy-based methods, and capillary electrophoresis-based systems for inorganic ion detection. Attention has been given to the core principle of detection while reporting recent sensors developed using the mentioned concepts. The latest works reported on the different sensing methodologies point towards the trend of developing low-cost, easy to use, field-deployable or portable sensing systems aimed towards improving technology adoption in crop production leading to efficient site-specific soil and crop management which in turn will bring us closer to reaching sustainability in the practice of agriculture.
