TOWARD A BETTER CLEANING AND SELECTIVITY IN ELECTROANALYSIS: TIO2-BASED SENSORS AND ENANTIOSELECTIVE MATERIALS
type: CreativeWork
description: In the latest years the concern on environmental issues has grown dramatically. One of the major problems of environmental chemistry are emerging contaminants (ECs), which are not commonly monitored in the environment. They can cause undesirable effects on ecosystems and human health. This group of substances includes pharmaceutical and personal care products (PPCPs), endocrine disrupting chemicals, hormones, pesticides, plasticizers, flame retardants and so on. Some of these emerging contaminants have been added to the list of priority substances and corresponding individual environmental quality standards have been set. These substances include pharmaceuticals (macrolide antibiotics, estrogenic hormones, carbamazepine, diclofenac, ibuprofen), industrial chemicals (bisphenol A), metals (silver) and pesticides (triclosan, nicosulfuron, glyphosate, neonicotinoids, pyrethroids). Modern analytical techniques can easily detect emerging contaminants in the environment, but they are expensive and time consuming. In this context, electrochemical sensors could overcome these problems since they are easy to use, they can be portable, disposable and they can be adapted to every necessity.Thanks to their properties and characteristics, such as high active surface, increased surface/volume ratio, increased selectivity, nanomaterials are broadly used in a wide range of applications, like energy, catalysis and electroanalysis. One of the most valued characteristics for modern sensors are self-cleaning properties, i.e. the possibility to use the sensor more than once and to detect analytes in complex matrices, remotely without the need to clean and restore them for long time. Starting from the aforementioned points, the aim of this PhD thesis is the study of different materials to enhance the selectivity and the cleaning properties of electrochemical sensors. In particular, titanium dioxide was studied for its photocatalytic activity to give photo-renewable properties to electroch…
