The rapid evolution of chemical and bioanalytical sciences is driven by micro and nanomaterials whose performance is governed by engineered interfaces. At the nanoscale, surface chemistry controls molecular recognition, signal transduction, sensitivity, and selectivity, enabling analytical capabilities beyond those of conventional materials. Nano-enabled interfaces based on quantum dots, nanozymes, molecular frameworks, mesoporous structures, thin films, and hybrid materials are central to advanced chemical and biosensing platforms. Recent advances in interface functionalization and bio-recognition have enabled sensitive sensing for point-of-care diagnostics, environmental analysis, and biomedical applications. This Topical Collection focuses on original research articles reporting innovative nano-interface-based analytical methods and sensing devices, emphasizing interface-driven signal amplification and real-world analytical applicability.

With advancements in technology, precision agriculture—a digitized and intelligent model—is revolutionizing traditional agricultural practices. The core of precision agriculture relies on real-time, high-precision system monitoring data, yet conventional sensors, being bulky, costly, and insufficiently intelligent, struggle to meet these demands. The development of nanomaterials and wearable technologies has enabled the gradual adoption of highly flexible and accurate flexible wearable technologies in precision agriculture.

This topical collection aims to gather cross-cutting research at the intersection of precision agriculture and wearable sensing technologies. Focusing on wearable sensing technologies, it highlights innovative fabrication of nanomaterials and devices to address detection needs in precision agriculture. Wearable energy-harvesting devices, capable of providing continuous power for sensors, help alleviate concerns about energy supply. Specific themes include, but are not limited to: Health biomarker detection and evaluation: Wearable sensors for plant/animal stress biomarkers (e.g., volatile organic compounds, hormones).

Growth dynamics monitoring: Wearable systems for real-time tracking of nutrient uptake, growth states (via motion capture), and environmental adaptability in crops and livestock.

Self-powered sensing systems: Wearable energy-harvesting technologies (e.g., biofuel cells, solar energy) to ensure long-term wireless operation of sensors in agricultural settings.

Agricultural product safety and quality assurance: Edible/wearable sensors attached to food surfaces for real-time monitoring of freshness, flavor, and contamination risks.

Livestock transportation monitoring: Wearable devices for continuous tracking of vital signs (e.g., body temperature, heart rate) in live animals, reducing losses during transport.
