Special Issue Information

Dear Colleagues,

The composites of carbon nanomaterials and transition metal oxides have many different applications, e.g., in catalysis, sensors and biosensors, energy storage and conversion, environmental protection, medicine, and diagnostics and health monitoring. These materials’ properties can be widely changed through various methods used for their production and functionalization. Commonly used nanomaterials include carbon nanotubes, graphene, carbon nanofibers, and transition metal particles and their compounds.

Developing composite materials is a process involving constant progress, and these materials’ have enormous potential in the field of bioapplications. Their main functional properties include excellent electrical and thermal conductivity and electrochemical and thermal stability. Moreover, studies have shown that nanocomposites have excellent biocompatibility and antimicrobial properties, greatly enhancing their applicability in biomedicine. Nanostructures can penetrate human cells, making the diagnosis and treatment of diseases more achievable. Accurately monitoring known molecules, detecting new molecules, and understanding their properties contribute to the search for new drug candidates.

This Special Issue welcomes full or review articles on new results related to the bioapplications of composite nanomaterials with particular emphasis on biosensors. All article submissions should involve research at the molecular level and verified experiments.

The aim of this paper is to investigate the influence of the molecules of conducting polymers on the properties of potentiometric sensors. Two conducting polymers, poly(3-octylthiophene-2,5-diyl) and poly(3,4-ethylene-1,4-dioxythiophene), were compared in the context of the design of ion-selective electrodes. This study offers a comparison of the most popular conducting polymers in the context of the design of potentiometric sensors. Firstly, the properties of both materials, such as their microstructure, electrical performance, wettability, and thermic properties, were examined. Subsequently, conducting polymers were applied as transducer layers in potassium-selective sensors. The properties of both groups of sensors were evaluated using the potentiometry method. Research has shown that the presence of poly(3-octylthiophene-2,5-diyl) (POT) in the transducer layer makes it superhydrophobic, leading to a long lifetime of sensors. On the other hand, the addition of poly(3,4-ethylene-1,4-dioxythiophene) polystyrene sulfonate (PEDOT:PSS) allows for the enhancement of electrical capacitance parameter values, which beneficially influence the stability of the potentiometric response of sensors. Both examined conducting polymers turned out to be perfect materials for transducer layers in potentiometric sensors, each being responsible for enhancing different properties of electrodes.
