EVANSTON, Ill. — Using an atomic force microscope tip as a pen and different single-stranded DNA as inks, scientists at Northwestern University have demonstrated a technique that could lead to the ultimate high-density gene chip because it takes gene chips to the limit of miniaturization — down to the scale of the DNA molecules themselves.
The above story is based on materials provided by Northwestern University. Note: Materials may be edited for content and length.
