Abstract

In this paper, we developed a new method for label-free detection of biomolecules by using the nanowall array chips. Our method is based on the detection of diffracted light by nanostructures inside a microchannel, and also has a great potential not only to distinguish the difference between water and buffer solution but detect biomolecules without any fluorescent molecules. Moreover, as for the detection limit, DNA molecules as much as zepto-mole level could be detected by using our label-free method.
