A ratiometric upconversion nanoprobe enables super-resolution imaging sensing of biothiols in living cells

Chem Commun (Camb). 2024 Apr 2. doi: 10.1039/d3cc06242b. Online ahead of print.ABSTRACTWe have developed an upconversion luminescent ratiometric nanoprobe, specifically designed for detection of biothiols with high sensitivity (∼25 nM) at the single-particle level. Using a single-particle localization and rendering method, this nanoprobe enables super-resolution imaging sensing of biothiols within a confined 22 nm space in living cells.PMID:38563651 | DOI:10.1039/d3cc06242b
