文摘
- •
An imidazolium-based ionic liquid and CdSe quantum dots were incorporated in graphite paste electrode to quantify minoxidil.
- •
The use of 1-ethyl-3-methyl-imidazolium:PF6 (EtMIMPF6) as a hydrophilic binder resulted in increased capacitive current.
- •
To enhance the faradaic signal, we employed a glucose-capped CdSe QDs.
- •
The results DFT calculations showed that the presence of QDs cannot significantly alter HOMO-LUMO energy levels.
- •
For the first time, a detailed mechanism for oxidation of minoxidil was proposed.
