Abstract
The method of producing eggshell-derived nanoparticles may include steps of adding eggshell powder to methanol to form a solution; adding the solution dropwise to boiling water under ultrasonic conditions; incubating the resulting solution under continuous stirring at 200-800 rpm; and drying the resulting solution to obtain the eggshell-derived nanoparticles. The method produces nanoparticles of between 5 and 100 nm. Cytotoxicity testing shows that the nanoparticles exhibit anticancer activity against human breast cancer and lung cancer cell lines.
