Glass-based geometry-induced electrostatic trapping devices for improved scattering contrast imaging of nano-objects
Fabrication of new glass-based geometry-induced electrostatic (GIE) trapping devices. Much higher SNR ratios of gold NPs are achieved with the glass-based devices. Detection of 40nm gold particles in GIE trapping devices using iSCAT microscopy. 40nm gold particles in glass devices show higher SNR than 80nm gold particles in silicon devices. Trapping of 60nm gold particles using new glass-based GIE trapping devices is shown.
