In this paper, we fabricate gold structures in different dimensions using the colloidal lithography method, which is less costly and easier than other lithography methods, Then, using the surface plasmonic stimulation of these structures, they can be used as plasmonic tweezers for particle trapping, and lab on chip devices. Two of the important advantages of these plasmonic tweezers Compared with other plasmonic tweezers are: The relative simplicity of their fabricating process and the use of a desired wavelength laser (using the change of fabricating parameters) to stimulate surface plasmons.
