3. A method of forming nanocomposite film, the method comprising:

preparing an aqueous Crocus sativus extract;

dropwise adding silver nitrate solution to a dispersion of titanium dioxide nanoparticles to obtain a mixture;

dropwise adding the aqueous Crocus sativus extract to the mixture with continuous stirring to obtain nanocomposite powder,

adding cornstarch to deionized water along with glycerol as plasticizer with continuous stirring to obtain a second mixture;

adding the nanocomposite powder to the second mixture to obtain a third mixture; and

forming the nanocomposite film using the third mixture.
