Special Issue Information

Dear Colleagues,

The Special Issue “Membrane-Based Sensors” will focus on the development of polymeric materials with novel chemical sensing ability, mechanism, and transduction principles. It seeks to bring an inclusive perspective to the development of materials for chemosensors where the mechanism of signal transduction emerges from the properties of the materials. The section may include approaches for the design, synthesis, characterization, and modeling of materials for membrane and sensors applications. Different classes of materials will be included: inorganic, organic, and hybrid nanomaterials (quantum dots, metallic, and semiconducting nanoparticles, carbon nanomaterials), two-dimensional materials, metal–organic frameworks, supramolecular systems (macrocyclic compounds, cavitand molecules), smart soft materials (stimuli-responsive hydrogels and polymers), molecularly imprinted polymers, and DNA-based sensors. 

The purpose of this Special Issue is to collect advances in fundamental research and technology development, as well as innovative sensors for different applications such as water monitoring, including different sensor platforms and configurations, sensing mechanisms, and applications. Reviews must offer a critical overview of the state-of-the-art of fundamentals, technologies, and applications pertinent to water quality monitoring. 

Potential topics include but are not limited to the following: 

  • Chemo- and biosensors;
  • Imprinted polymers and their uses;
  • Polymeric membranes based on chromatography, electrophoresis, colorimetry, enzymes and antibodies; 
  • Theoretical and simulation studies; 
  • Multiplexing of several physical and chemical parameters of sensors based on polymeric materials; 
  • Applications, such as agricultural, livestock, food processing and aquaculture activities, harsh environments or monitoring of water-intensive industries.

Solid-contact ion-selective electrodes (SC-ISEs) have shown great potential for routine and portable ion detection. The introduction of nanomaterials as ion-to-electron transducers and the adoption of different performance-enhancement strategies have significantly promoted the development of SC-ISEs. Herein, new solid-contact ion-selective electrodes, along with the implementation of multiwalled carbon nanotubes (MWCNTs) as ion-to-electron transducers and potassium tetrakis (p-chlorophenyl) borate (KTpClB) as lipophilic ionic additives, were presented for the detection of isoproturon (IPU) and diuron (DU) herbicides. Molecularly imprinted polymers (MIPs), with special molecule recognition properties for isoproturon (IPU) and diuron (DU), were prepared, characterized, and introduced as sensory recognition materials in the presented electrodes. Sensors revealed a near-Nernstian response for both isoproturon (IPU) and diuron (DU) with slopes of 53.1 ± 1.2 (r2 = 0.997) and 57.2 ± 0.3 (r2 = 0.998) over the linear ranges of 2.2 × 10−6–1.0 × 10−3 M and 3.2 × 10−6–1.0 × 10−3 M with detection limits of 8.3 × 10−7 and 1.4 × 10−6 M, respectively. The response time of the presented sensors was found to be <5 s and the lifetime was at least eight weeks. The sensors exhibited good selectivity towards isoproturon (IPU) and diuron (DU) in comparison with some other herbicides, alkali, alkaline earth, and heavy metal ions. The presented sensors were successfully applied for the direct determination of isoproturon (IPU) and diuron (DU) in real water samples. Full article
