Special Issue Information

Dear Colleagues,

Semiconductor electronics and photonics based on advanced nanomaterials and nanotechnologies have been the key driving force of micro/nano-sensors. Nowadays, with the development of high-speed data communication, the growing demand for micro/nano-sensors presents unprecedented opportunities and challenges. In the building of Smart Cities, micro/nano-sensors are the essential component of the Internet of Things (IoT) and encounter high demand for their categories, performance, application scenarios, etc. Various sensors are needed for different application fields, such as environmental pollution monitoring, hazardous chemical spill warning, early disease diagnosis, and healthcare reminders. Measurement accuracy is vital for some practical applications. Thus, excellent sensing performance is required for the sensors to hit these metrics.

Rational design for advanced nanomaterials is a promising solution for fabricating sensors and enhancing their sensing performance. Advanced technologies, including crystal facet controlling, vacancies regulation, morphology design and controllable assembling of individual nanomaterials, and hetero-integration of multi-composition, multi-structure, and multi-function at the nanoscale, can create a new generation of integrated micro/nano-sensors with unprecedented performance or unique functions to break the boundaries of traditional technologies.

The Special Issue “Advanced Nanomaterials and Nanotechnologies for Micro/Nano-Sensors” seeks papers on chemical/biological sensors based on the electrical or optical properties of advanced novel nanomaterials. Authors are invited to submit articles focused on trace detection, selective enhancement, fast response, and other aspects. Papers on the characterization and evaluation of sensing performance or the completion of sensing mechanistic discussions of experimental phenomena will also be very well received.

With the growing severity of air pollution, monitoring harmful gases that pose risks to both human health and the ecological environment has become a focal point of research. Titanium dioxide (TiO2) demonstrates significant potential for application in SO2 gas detection. However, the performance of pure TiO2 is limited. In this study, TiO2 nanospheres and MoSe2 nanosheets were synthesized using a hydrothermal method, and the gas-sensing properties of TiO2/MoSe2 nanostructures for SO2 detection were investigated. The TiO2/MoSe2 composites (with a TiO2-to-MoSe2 volume ratio of 2:1) were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). The TiO2/MoSe2 sensor exhibited high sensitivity to SO2; the response to 100 ppm of SO2 reached as high as 59.3, with a significantly shorter response and recovery time (15 s/13 s), as well as excellent repeatability, selectivity, and long-term stability. The experimental results suggest that the enhanced SO2 adsorption capacity of the TiO2/MoSe2 composite can be attributed to the formation of an n-n heterojunction and the unique microstructural features of TiO2/MoSe2. Therefore, the TiO2/MoSe2 sensor represents a promising candidate for rapid SO2 detection, providing a theoretical foundation for the development and application of high-performance SO2 sensors.

The booming expansion of nanotechnology poses the problem of environmental pollution by nanoparticles (NPs). The available methods for sensing and removing NPs from the environment are typically lengthy and instrumentally demanding. The recent introduction of NP-imprinted polymers (NPIPs), either as films or bulk materials, is an important step toward the simple and fast sensing and removal of NPs from water and air. Similarly to the well-established molecularly imprinted polymers, in NPIPs, an organic or inorganic polymeric material is first obtained with embedded NPs. Then, the NPs are chemically or physically removed by acting as a template, i.e., leaving a polymeric matrix with cavities of the same shape and dimensions. After the first examples were published in 2014, the literature has so far reported an increasing number of NPIPs that are capable of reuptaking NPs from water (or, more rarely, air), with remarkable size and shape selectivity. By laying an NPIP layer on a reporter (typically an electrode), devices are obtained that are capable of sensing NPs. On the other hand, bulk NPIPs can reuptake massive amounts of NPs and have been used for the quantitative removal of NPs from water. This review begins with an overview of NP-imprinted hollow capsules, which can be considered the ancestors of NPIPs, both as conception and as preparative methods. Then, the literature on NPIPs is reviewed. Finally, the possible evolutions of NPIPs are highlighted from the perspective of stepping toward their real-life, field use. Full article
