Theoretical Sensing Performance for Detection of Cyclophosphamide Drug by Using Aluminum Carbide (CAl) Monolayer: a DFT Study.

Because nanomaterials are highly reactive and electronically sensitive towards a variety of drug molecules, they are thought of as efficient drug sensors. In the present research study, an aluminum carbide (CAl) monolayer is employed and its interaction is examined with cyclophosphamide (CP) by performing DFT computations. The CAl monolayer is highly reactive and sensitive towards CP according to the computations. CP interacts with the CAl monolayer with the adsorption energy of -31.39 kcal/mol. A considerable charge transfer (CT) indicates an enhancement in the conductivity. Also, the charge density is explained based on the electron density differences (EDD). The decrease in CP/CAl energy gap (E) by approximately 52.91% is due to the remarkable effect of adsorption on the LUMO and the HOMO levels. Therefore, due to the decrease in E which can generate an electrical signal, the electrical conductivity is considerably increased. These results suggest that the CAl monolayer can be employed as a proper electronic drug sensor for CP. Also, the recovery time for the desorption process of CP form the surface of CAl is 351 s at 598 K.
