Upconversion nanothermometry: enabling high brightness in a thermal field

点击翻译按钮获取中文摘要

This project aims to create a unique library of nanometer scale temperature-responsive sensors for bio-discoveries, disease diagnostics, device manufacturing and anti-counterfeiting, by investigating a new observation in enhanced photon energy conversion. The project will develop a thermal-field diagnostics approach to reveal interfacial cation-ligand behaviours of luminescent hybrid nanomaterials, and modify the otherwise quenching molecules to facilitate energy upconversion. This will link surface chemistry and heterogeneous interfacial physics. It will allow ratiometric fluorescence to achieve extremely high sensing sensitivity in intracellular nanothermometry, enabling super resolution thermal imaging of living cells.
