A Modified Electrochemical Sensor Based on N,S-Doped Carbon Dots/Carbon Nanotube-Poly(Amidoamine) Dendrimer Hybrids for Imatinib Mesylate Determination.

Imatinib mesylate, an anticancer drug, is prescribed to treat gastrointestinal stromal tumors and chronic myelogenous leukemia. A hybrid nanocomposite of N,S-doped carbon dots/carbon nanotube-poly(amidoamine) dendrimer (N,S-CDs/CNTD) was successfully synthesized and used as a significant modifier to design a new and highly selective electrochemical sensor for the determination of imatinib mesylate. A rigorous study with electrochemical techniques, such as cyclic voltammetry and differential pulse voltammetry, was performed to elucidate the electrocatalytic properties of the as-prepared nanocomposite and the preparation procedure of the modified glassy carbon electrode (GCE).

Fluorescent cellulosic composites based on carbon dots: Recent advances, developments, and applications.

Cellulose and its derivatives are highly applicable in advanced applications on the basis of fluorescence phenomena. Carbon dots (CDs) have also appealing properties, such as high photoluminescence, easy synthesis pathway, cheap source materials, chemical stability, and easy functionalization. In this regard, combination of luminescent CDs with natural cellulosic materials could adjust or expand its desirable properties and have advanced applications.
