Facile preparation of a hydrophilic Eu-based ratiometric fluorescent nanosensor for Cu2+ ion detection and imaging in living cells
{{output}}
In this work, a hydrophilic Eu-based ratiometric fluorescent nanosensor (PAAC-Eu) was developed for Cu2+ ion detection in aqueous solutions and imaging in living cells. The sensor was prepared via a simple one-step reaction at room temperature, leveraging the ... ...
