		Quality control of biochip

		Biochip tchickness measurement

		No labelling


		Standard surf

		Plug-in Sarfus 3D

		Optical Microscope with DIC mode

A DNA biochip is prepared on a standard surf. Here we provide a 3D representation of one biochip spot acquired by Sarfus®. An optical thickness profile can be displayed, which allows a straightforward measure of the spot thickness (16 Å in real thickness in the present study).
