Special Issue Information

Dear Colleagues,

Chemosensors and biosensors have attracted widespread attention due to their great potential for detecting or monitoring biological and chemical information. Advances in chemosensor and biosensor technology have been driven by innovative progress in nanomaterials. The design, synthesis, and preparation of various nanomaterials have injected new impetus into the development and application of chemosensors and biosensors, providing a transducer device basis for the field of smart sensing.

The aim of this Special Issue is to provide selected contributions on recent advances in the field of nanomaterial-based sensor research and application in smart sensing. Authors are, therefore, invited to submit either review articles or original research articles related to novel nanomaterials, sensor design, sensitive mechanisms, and smart sensing applications.

The detection and monitoring of toxic and harmful gases play a vital role in environmental protection, human health, and industrial and agricultural production. However, it is still challenging to develop gas sensors for the detection of toxic and harmful gases with high sensitivity, good recovery and excellent selectivity. In this study, WO3/Al2O3/graphite composite materials were used for an MEMS 2-CEES gas sensor (dichlorodiethyl sulfide simulation), and the corresponding sensing properties were explored. The experimental results show that when the working temperature is 340 °C, the response of the sensor to 2-CEES gas with a concentration of 5.70 ppm is 69%, the response time is 5 s and the recovery time is 42 s. The sensor also has the advantages of long-term stability and high selectivity. Furthermore, the MEMS gas sensor array based on WO3/Al2O3/graphite composite materials has been achieved and also exhibits excellent sensing performance. Overall, this study provides a strategy for realizing high-performance dichlorodiethyl sulfide gas sensors. Full article
