“…[1,2,3,4] Development of colorimetric and fluorescence-based detection methods that target precise recognition of bioactive metals such as copper (Cu 2+ ) and aluminum (Al 3+ ) is a topic of high interest among researchers. [5,6,7,8,9,10,11] Cu 2+ is the third most abundant heavy metals after Fe 3+ and Zn 2+ in the human body. Several biological processes require Cu 2+ in optimum amounts.…”

“…A fluorescent chemosensor based on a dissolvable conjugated polymer, oligo (1-pyreneboronic acid) (OPYBA), obtained by electrosynthesis for highly selective analysis of Cu 2+ at ultra-trace levels was reported by Zhang et al [168]. The polymer was first obtained by potentiostatic electropolymerization from monomer in an can/tetrabutylammonium tetrafluoroborate solution (vs Ag/AgCl at 1.0 V), de-doped with dilute HCl, and dissolved in THF (5.0 × 10 −8 M) for analysis of Cu 2+ in two linear ranges of 25 pM-88.2 µM and 188-750 µM with an LDL limit of 23 pM.…”

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.

Ions are present throughout our environment-from biological systems to agriculture and beyond. Many important processes and mechanisms are driven by their presence and their relative concentration. In order to study, understand and/or control these, it is important to know what ions are present and in what concentration-highlighting the importance of ion sensing. Materials that show specific ion interaction with a commensurate change in measurable properties are the key components of ion sensing. One such type are conducting polymers. Conducting polymers are referred to as 'active' because they show observable changes in their electrical and optical (and other) properties in response to changing levels of doping with ions. For example, p-type conducting polymers such as poly(3,4ethylenedioxythiophene) and polypyrrole, can transition from semi-conducting to metallic in response to increasing levels of anions inserted into their structure. Under certain circumstances, conducting polymers also interact with cations-showing their utility in sensing. Herein, recent advances in conducting polymers will be reviewed in the context of sensing ions. The main scope of this review is to critically evaluate our current understanding of ion interactions with conducting polymers and explore how these novel materials can contribute to improving our ion-sensing capabilities.
