Special Issue Information

Dear Colleagues,

Functional nanomaterials with attractive electronic and photoelectronic properties show great potential in various fields. In recent decades, tremendous research efforts have been devoted to the design of photoactive and electroactive nanomaterials for qualitative and quantitative analysis applications. This Special Issue focuses on the preparation, surface modification and functionalization of nanomaterials for healthy, environmental and bio-related area sensing.

The major technological progress in the last few decades has resulted in the elaboration of numerous novel instrumental analytical methods, allowing for the detection of molecules at very low concentrations. It requires the development of advanced materials that can serve as components of detectors. Various new materials have found application as detectors elements, aiming to enhance the transduction of signals. Nanomaterials with unique optical and electrochemical properties are advantageous in the development of novel chemical sensors and biosensors.

This Special Issue will showcase the most recent advances in the applications of nanomaterials, with a focus on their application, including but not limited to sensors, labelling, imaging and therapeutic applications in biomedicine.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: sensors for the environment pollution; sensors for ions; sensors for organic compounds; and sensors for biomolecules and biological interest. Optical, electrochemical and photoelectrochemical sensors based on different types of nanomaterials are also welcome.

We look forward to receiving your contributions.

In this study, β-Bi2O3 nanosheets functionalized with bisphenol A (BPA) synthetic receptors were developed by a simple molecular imprinting technology and applied as the photoelectric active material for the construction of a BPA photoelectrochemical (PEC) sensor. BPA was anchored on the surface of β-Bi2O3 nanosheets via the self-polymerization of dopamine monomer in the presence of a BPA template. After the elution of BPA, the BPA molecular imprinted polymer (BPA synthetic receptors)-functionalized β-Bi2O3 nanosheets (MIP/β-Bi2O3) were obtained. Scanning electron microscopy (SEM) of MIP/β-Bi2O3 revealed that the surface of β-Bi2O3 nanosheets was covered with spherical particles, indicating the successful polymerization of the BPA imprinted layer. Under the best experimental conditions, the PEC sensor response was linearly proportional to the logarithm of BPA concentration in the range of 1.0 nM to 1.0 μM, and the detection limit was 0.179 nM. The method had high stability and good repeatability, and could be applied to the determination of BPA in standard water samples. Full article

Recently, nanopore technology has emerged as a promising technique for the rapid, sensitive, and selective detection of various analytes. In particular, the use of nanopores for the detection of copper ions has attracted considerable attention due to their high sensitivity and selectivity. This review discusses the principles of nanopore technology and its advantages over conventional techniques for copper detection. It covers the different types of nanopores used for copper detection, including biological and synthetic nanopores, and the various mechanisms used to detect copper ions. Furthermore, this review provides an overview of the recent advancements in nanopore technology for copper detection, including the development of new nanopore materials, improvements in signal amplification, and the integration of nanopore technology with other analytical methods for enhanced detection sensitivity and accuracy. Finally, we summarize the extensive applications, current challenges, and future perspectives of using nanopore technology for copper detection, highlighting the need for further research in the field to optimize the performance and applicability of the technique.
