About this collection
With the development of the world population and increasing life expectancy, concerns toward human health are growing. The major obstacle to understanding the roles that biological molecules play in physiological and pathological events is a lack of reliable and efficient methods, due to a large variety of chemicals coexisting with dynamic variations and interacting with each other. In this cross-journal themed collection, guest edited by Yang Tian (East China Normal University) we cover themes including, but not limited to:
1) Fundamental investigations on precise construction and regulation of sensing micro/nano-interface toward health analysis.
2) Analytical approaches for accurate measurements of chemical expression in cells and living animals.
3) Precise imaging and biosensing of single cells.
4) Portable devices for health analysis based on stretchable sensors.
5) Artificial intelligence applications for health analysis.
