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:

• One- and two-dimensional nanostructured materials for sensor applications (e.g., MXenes, metal–organic frameworks (MOFs), and transition metal dichalcogenides (TMDs))
• Hollow nanomaterial-based sensors in environmental remediation and monitoring
• Nanomaterial-based optical and electrochemical sensors
• Nanomaterial-based wearable, flexible, and implantable sensors (e.g., skin sensors, tactile sensors)
• Nanomaterial-based bioresorbable sensors
• Enzyme-mimicking nanomaterials for biosensing applications
• Deformable and stretchable nanosensors with integrated functional nanomaterials
• Engineered nanomaterials for bioenvironmental applications
• Smart nanomaterial-based sensors for food quality monitoring
• Nanomaterial-based molecularly imprinted polymers for sensing platforms
• Fluorescent hybrid nanomaterials for water, food, and bioenvironmental sensing
