International audienceIn this work, we report the development of a highly sensitive capacitance chemical sensor based on a copper C, C, C, C-tetra-carboxylic phthalocyanine-acrylate polymer adduct (Cu(II) TCPc-PAA) for phosphate ions detection. A capacitance silicon nitride substrate based Al-Cu/Si-p/SiO2/Si3N4 structure was used as transducer. These materials have provided good stability of electrochemical measurements. The functionalized silicon-based transducers with a Cu(II) Pc-PAA membrane were characterized by using Mott-Schottky technique measurements at different frequency ranges and for different phosphate concentrations. The morphological surface of the Cu(II) Pc-PAA modified silicon-nitride based transducer was characterized by contact angle measurements and atomic force microscopy. The pH effect was also investigated by the Mott-Schottcky technique for different Tris-HCl buffer solutions. The sensitivity of silicon nitride was studied at different pH of Tris-HCl buffer solutions. This pH test has provided a sensitivity value of 51 mV/decade. The developed chemical sensor showed a good performance for phosphate ions detection within the range of 10(-10) to 10(-5) M with a Nernstian sensitivity of 27.7 mV/decade. The limit of detection of phosphate ions was determined at 1 nM. This chemical sensor was highly specific for phosphate ions when compared to other interfering ions as chloride, sulfate, carbonate and perchlorate. The present capacitive chemical sensor is thus very promising for sensitive and rapid detection of phosphate in environmental applications

“…The amount of P estimated with the PO 4 3− -ISE was in good agreement with the amount found by the standard spectroscopy method, indicating potential applicability of the developed sensing probe for soil nutrient monitoring and rational soil fertigation assessments. The Cu-phthalocyanines were also reported as hydrophosphate-selective ionophores [75,76]. Thus, in [75] a copper monoaminophthalocyanine (CuMAPc) covalently attached to poly(n-butyl acrylate) (PnBA) was bound to a gold electrode pre-coated with the PEDOT poly(3,4-ethylenedioxythiophene), which was used as an ion-to-electron transducer.…”

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 SS-ISE sensor for HPO 2− 4 based on copper monoamino phthalocyanine (CuMAPc) covalently attached to poly (n-butyl acrylate) (PnBA) was reported in [109]. The SS-ISE was constructed by the application of a thin film of a polymer cocktail containing a CuMAPc-PBDA ionophore and benzyl-dimethylhexadecyl ammonium chloride (BDMHAC) as a lipophilic cationic additive onto a gold electrode pre-coated with the conducting polymer poly (3,4- Electro-analytical reactions of phosphate ions with metallic compound electrodes can be characterized using EC methods and have been reported for developing ISEs for P detection.…”

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.
