Colorimetric and fluorimetric dual mode detection of Al3+ in aqueous solution was achieved using a carbon dots/rutin (CDs/rutin) coexisting system.
A fluorometric and colorimetric dual mode sensing platform based on hybridized carbon dots (Cdots) and gold–silver core–shell nanoparticles (Au@Ag NPs) has been established for the sensitive detection of trace Cu2+ ions in aqueous solution.
Fluorescent and color sensors for ketamine HCl determination. A dual-mode nanoprobe for the detection of a club drug in spiked beverage.
Nitrogen doped carbon dots (N-CDs) were synthesized by a one-step hydrothermal method with dopamine and ethylenediamine.
