Nanomaterial-based sensors are interesting tools that allow for the precise detection at the nanomolar to sub-picomolar scales and can be useful in applications such as healthcare monitoring, environmental pollutant detection, and food quality analysis. Nanomaterials offer unique physicochemical features, a large electroactive and recognition surface area, and have been widely exploited to increase device sensing performance at the nanoscale. As a result, they play an important role in bioenvironmental and food science.
Contributions on innovative nanomaterial synthesis, characterization methods, rational design, and application of nanomaterial-based sensors to all types of water quality, food quality, and healthcare monitoring and sensing platforms will be considered for this thematic issue. Research contributions to this thematic issue may include but are not limited to the following topics:
