“…The surface charge at the basis of the transduction can be generated on the micro-sized gate area when it is chemically modified to interact with different target compounds. Ionophore membranes and antibodies have been exploited for the detection of NH 4 + , NO 3 − [ 145 ], and influenza virus [ 146 ], respectively. Jang et al [ 147 ] proposed an ISFET sensor with a 10 µm × 10 µm sensing area for the detection of human IL-5, with an approach that is similar to enzyme-linked immunosorbent assays (ELISAs).…”

Electrode miniaturization has profoundly revolutionized the field of electrochemical sensing, opening up unprecedented opportunities for probing biological events with a high spatial and temporal resolution, integrating electrochemical systems with microfluidics, and designing arrays for multiplexed sensing. Several technological issues posed by the desire for downsizing have been addressed so far, leading to micrometric and nanometric sensing systems with different degrees of maturity. However, there is still an endless margin for researchers to improve current strategies and cope with demanding sensing fields, such as lab-on-a-chip devices and multi-array sensors, brain chemistry, and cell monitoring. In this review, we present current trends in the design of micro-/nano-electrochemical sensors and cutting-edge applications reported in the last 10 years. Micro- and nanosensors are divided into four categories depending on the transduction mechanism, e.g., amperometric, impedimetric, potentiometric, and transistor-based, to best guide the reader through the different detection strategies and highlight major advancements as well as still unaddressed demands in electrochemical sensing.

“…The most widely used are electrochemical sensors composed of an ion-selective membrane and a transducer, which selectively respond to the presence of target molecules. These sensors have been applied to quantification of nitrate, nitrite, and ammonium in soil. Although electrochemical sensors allow rapid analysis without soil pretreatment or use of chemical agents, they suffer from drift over time, which requires frequent calibration (weekly to monthly) to correct the drifting .…”

Monitoring nutrients in the soil can provide valuable information for understanding their spatiotemporal variability and informing precise soil management. Here, we describe an autonomous in situ analyzer for the real-time monitoring of nitrate in soil. The analyzer can sample soil nitrate using either microdialysis or ultrafiltration probes placed within the soil and quantify soil nitrate using droplet microfluidics and colorimetric measurement. Compared with traditional manual sampling and lab analysis, the analyzer features low reagent consumption (96 μL per measurement), low maintenance requirement (monthly), and high measurement frequency (2 or 4 measurements per day), providing nondrifting lab-quality data with errors of less than 10% using a microdialysis probe and 2−3% for ultrafiltration. The analyzer was deployed at both the campus garden and forest for different periods of time, being able to capture changes in free nitrate levels in response to manual perturbation by the addition of nitrate standard solutions and natural perturbation by rainfall events.

“…These methods require collecting thousands of images stitched together and high processing power to analyze the data. On the other hand, miniaturized sensors require a microcontroller and a battery in a handheld device to measure the soil nutrients [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. The simplicity of the hardware allows for weeks or months of data collection before the batteries need to be replaced.…”

“…This work showcases the first-of-its-kind real-time continuous in situ soil nitrate measurement through the use of electrochemistry. This work presents an ion-selective electrode (ISE) incorporating tetradodecylammonium (TDDA) nitrate to increase selectivity towards nitrate ions [ 18 , 22 , 23 ]. Joly et al have demonstrated a ChemFET device capable of measuring nitrate concentrations in the range of 10 −1.5 –10 −5.5 M with a sensitivity of 56 mV/pNO 3 .…”

Sustainable agriculture is the answer to the rapid rise in food demand which is straining our soil, leading to desertification, food insecurity, and ecosystem imbalance. Sustainable agriculture revolves around having real-time soil health information to allow farmers to make the correct decisions. We present an ion-selective electrode (ISE) electrochemical soil nitrate sensor that utilizes electrochemical impedance spectroscopy (EIS) for direct real-time continuous soil nitrate measurement without any soil pretreatment. The sensor functionality, performance, and in-soil dynamics have been reported. The ion-selective electrode (ISE) is applied by drop casting onto the working electrode. The study was conducted on three different soil textures (clay, sandy loam, and loamy clay) to cover the range of the soil texture triangle. The non-linear regression models showed a nitrate-dependent response with R2 > 0.97 for the various soil textures in the nitrate range of 5–512 ppm. The validation of the sensor showed an error rate of less than 20% between the measured nitrate and reference nitrate for multiple different soil textures, including ones that were not used in the calibration of the sensor. A 7-day-long in situ soil study showed the capability of the sensor to measure soil nitrate in a temporally dynamic manner with an error rate of less than 20%.
