Cation Pretreatment Enables the Saline Stability of a Near-Infrared Sensor for Dopamine

Ardemis Anoush Boghossian, Hanxuan Wang

Single-walled carbon nanotubes (SWCNTs) are wrapped with single-stranded DNA (ssDNA) to create near-infrared (NIR-II) fluorescent sensors for diverse analytes. However, the interaction between the negatively charged backbone of ssDNA and cations in biologi ...
