As described in the Sustainable Development Goals (SDGs), the protection of water environments is a significant social issue. To this end, the qualitative and quantitative investigation of causative agents is required to identify their effects on ecological systems. In this regard, the target water environments are not only microscale (i.e., cell) but also macroscale (i.e., ocean), which leads us to “cross-scale analysis”. Meanwhile, analytical methods with sufficient requirements for on-site sensing have not been fully established.
To address the above issues, we opened the thematic issue “Nanotechnology for cross-scale analysis: comprehensive evaluation of water environments”. We gratefully welcome original full research, letter, review, or perspective articles related (but not limited to) to design and development of:
