By replacing gold film with graphene, researchers have improved the performance of opto-thermoelectric tweezers. These new graphene-based opto-thermoelectric tweezers benefits from a much broader working wavelength range and a larger trapping area. They extend the working wavelength from visible band to the infrared and far-infrared bands, which are less harmful to biological samples. Owing to the ultrahigh thermal conductivity of graphene, this technology can achieve large-area particle ...
