Special Issue Information

Dear Colleagues,

Daily life is becoming even more complex, and the quality control of environmental, food, cosmetic, biological and pharmaceutical samples requires simple, rapid and cost-effective determination methods. A long-standing requirement is the development of electrochemical-sensing platforms for real sample characterization with high sensitivity, selectivity and versatility.

Carbon nanomaterials are considered the cornerstone of numerous investigations. Since the discovery of carbon nanomaterials, they have drawn considerable research attention and have shown great potential applications in many fields due to their fascinating electrochemical properties including high effective surface area, excellent electrical conductivity, electrocatalytic activity as well as high porosity and adsorption capability, making them potential candidates for electrochemical purposes, particularly sensing.

In order to broaden the scope of their application, the chemical functionalization of carbon nanomaterials has attracted great interest over the past several decades and produced various novel hybrid materials with specific applications. This can be achieved by specific functionalization of carbon nanomaterials with a variety of materials such as noble metals, metal oxides, polymers, etc.

This Special Issue aims to provide a comprehensive collection of the latest advances in functionalized carbon nanomaterials as potential sensing materials for electrochemical sensors. The advantages of carbon nanomaterials as sensor materials will be discussed along with future prospects. We hope that researchers active in this area will join us to promote the activities in this field of research.

We cordially invite you to submit an article to this Special Issue. We welcome short communications, full research articles, and timely reviews.

The anticipated diagnosis of cancers and other fatal diseases from the simple analysis of the volatiles emitted by the body (volatolome) is getting closer and closer from becoming reality. The promises of vapour sensor arrays are to provide a rapid, reliable, non-invasive and ready-to-use method for clinical applications by making an olfactive fingerprint characteristic of people’s health state, to increase their chance of early recovery. However, the different steps of this complex and ambitious process are still paved with difficulties needing innovative answers. The purpose of this review is to provide a statement of the blocs composing the diagnostic chain to identify the improvements still needed. Nanocomposite chemo-resistive transducers have unique prospects to enhance both the selectivity and sensitivity to volatile biomarkers. The variety of their formulations offers multiple possibilities to chemical functionalization and conductive architectures that should provide solutions to discriminations and stability issues. A focus will be made on the protocols for the collection of organic volatile compounds (VOC) from the body, the choice of vapour sensors assembled into an array (e-nose), in particular, chemo-resistive vapour sensors, their principle, fabrication and characteristics, and the way to extract pertinent features and analyse them with suitable algorithms that are able to find and produce a health diagnosis.
