At the sub 10nm scale you need stiff linkages to have predictable and consistent structures. Covalent 'organic' bonds give you stiff linkages at that scale while metals are goopy and electronically inconsistent. Proteins are organic nanotechnology where the 3D feature sizes of the (wet) tools is measured in fractions of angstroms. The best Intel can do is ~ two orders of magnitude larger resolution, 2D, dry.
