DES-N-doped oxygenated carbon dot colloidal solutions for light harvesting and bio-imaging applications

Abstract

A novel colloidal system comprising choline oleate in deep eutectic solvent (DES: choline chloride–ethylene glycol) is developed and utilized for in situ generation and stabilization of nanosized (1 to 3 nm) N-doped oxygenated, crystalline CDs via dissolution of gelatin.

Ecofriendly and sustainable Sargassum spp.-based system for the removal of highly used drugs during the COVID-19 pandemic

“…The monitoring of drug removal was carried out by fluorescence analysis using quantum dots (CDs), which are fluorescent materials with quasi-spherical form and are approximately 10 nm in size. CDs have been commonly used in a broad range of applications, including drug delivery ( Yuan et al 2017 ), bioimaging ( Damarla et al 2020 ), photocatalysis ( Fernando et al 2015 ), and as sensors ( Cui et al 2017 ) due to their unique optical properties, high photostability, low toxicity, biocompatibility, and inexpensive nature. Fluorescent sensors are often used to detect many ions owing to their simplicity and sensitivity.…”
