Special Issue Information

Dear Colleagues,

The development of supramolecular chemistry by Pedersen, Cram, and Lehn, in the 1960s, brought forth the growth of a new research field called chemical sensors or chemosensors. These are molecules having receptor or host units devoted to providing information about the chemical composition of its environment through selective interaction with target molecules (guest molecules). The chemical sensors are usually organic or organometallic, low-mass molecules with a number of drawbacks: They are generally water insoluble, exhibit moderate to low light and thermal stability, and tend to migrate when they are dispersed in physical supports.

In a step forward, polymers with main chain, or lateral binding sites, also called host or receptor sub-units, opened the door for cutting-edge sensing applications in solution or gas phases, i.e., the detection and quantification of cations, anions, or neutral molecules. Polymers are materials with good thermal and mechanical resistances that can be transformed into solids of any shape. Accordingly, they can be easily transformed into end materials, such as films or coatings, to produce costless sensing devices, such as “naked-eye” sensory films, or to integrate them in conventional analytical techniques to detect gases or target species in solution. Moreover, sensory polymers can be designed to be soluble in water or in organic media so as to be exploited in solution as stable and easily-recovered sensory materials.

This Special Issue on polymer-based chemical sensors is devoted to the discussion and dissemination of the latest research in this quickly-evolving field. Emphasis will be placed on the preparation and applications of organic and hybrid polymers as sensing materials for the detection of chemicals of interest in solution and in the gas phase, in civil security and in the biomedical, food, environmental, and industrial fields, etc.

Nanocomposite-based quantum resistive vapour sensors (vQRS) have been developed from the assembly of hybrid copolymers of polyhedral oligomeric silsesquioxane (POSS) and poly(methyl methacrylate) (PMMA) or poly(styrene) (PS) with carbon nanotubes (CNT). The originality of the resulting conducting architecture is expected to be responsible for the ability of the transducer to detect sub-ppm concentrations of ammonia and formaldehyde at room temperature despite the presence of humidity. In particular, the boosting effect of POSS is evidenced in CNT-based nanocomposite vQRS. The additive fabrication by spraying layer-by-layer provides (sLbL) is an effective method to control the reproducibility of the transducers’ chemo-resistive responses. In dry atmosphere, the two types of sensors showed a high sensitivity towards both hazardous gases, as they were able to detect 300 ppb of formaldehyde and 500 ppb of ammonia with a sufficiently good signal to noise ratio (SNR > 10). They also exhibited a quick response times less than 5 s for both vapours and, even in the presence of 100 ppm of water, they were able to detect small amounts of gases (1.5 ppm of NH3 and 9 ppm of CH2O). The results suggest promising applications of POSS-based vQRS for air quality or volatolome monitoring. Full article

Review

Printing polymeric materials for electroanalytical applications

Stefano Cinti

Advances in design of selective interfaces and printed technology have mighty contributed to the expansion of the electroanalysis fame. The real advantage in electroanalytical field is the possibility to manufacture and customize a plenty of different sensing platforms, avoiding expensive equipments, skilled personnel, and economic effort. The growing development in polymer science have led to further improvements of the electroanalytical methods such as sensitivity, selectivity, reproducibility, and accuracy. This review provides an overview of the printing methods currently exploited to print polymeric materials, with an emphasis on the development of electronalytical sensors and biosensors.
