This investigation evaluates the physical and electrochemical modifications of bentonite nanoclay functionalized with bimetallic Ag-Au nanoparticles. In order to develop a better sensing material or film, nanoclay was researched. Bimetallic Ag-Au c nanoparticles were created. The science and engineering behind the design, synthesis, characterization, and use of materials and devices whose smallest functional organization, in at least one dimension, is on the nanoscale scale, or one billionth of a meter, is known as nanotechnology. As a result of its ability to influence the fundamental molecular structure, which allows control over the macroscopic chemical and physical properties, consideration of individual molecules and interacting groups of molecules in relation to the bulk macroscopic properties of the material or device becomes significant at these scales.
