Description

Label-free, Highly Sensitive and Intelligent Wearable Biosensors. This project aims to create fingertip-wearable sensors, known as “Raman Skins,” for rapid, on-the-spot detection of trace chemicals on surfaces like skin, fruit, and banknotes. These sensors will be made from plasmene nanosheets, which are ultra-thin nanomaterials. Through a unique fabrication process, we will develop a scalable method for producing these nanosheets and study how different nanocrystal sizes, shapes, and ligands affect their sensitivity. Powered by artificial intelligence, these wearable sensors will allow for efficient, label-free chemical analysis, offering new tools for enhanced wellbeing, food safety, and law enforcement. This technology has broad implications for public health, intelligent agriculture and safety.. Scheme: Discovery Projects. Field: 4018 - Nanotechnology. Lead: Prof Wenlong Cheng
