This present study is the first investigation of pazopanib-dsDNA binding using bare and modified GCE. The interaction was mainly evaluated based on the decrease of voltammetric signal of deoxyadenosine by differential pulse voltammetry using three different ways, including the incubated solutions, dsDNA biosensor, and nano-biosensor. The nanobiosensor was fabricated with the help of SnO2 nanoparticles and carbon hybrid material. The carbon material is derived from the waste mask, the most used personal protective equipment for the ongoing COVID-19 pandemic. Both materials were synthesized via the green synthesis technique and charac-terized by various techniques, including BET, TEM, SEM-EDX, AFM, XPS, and XRD. Spectrophotometric and molecular docking studies also evaluated the pazopanib-dsDNA binding. All calculations showed that pazopanib (PZB) was active in the minor grove region of DNA.
