The Asylum Research logo was created by electric field-mediated delivery of DNA fragments onto an amine-modified silicon substrate using the tip in an atomic force microscope, the MFP-3D AFM. The lateral force image is overlaid on the topography image. 2um x 2um scan, topography z= 3nm. Image courtesy of K. Unal, J. Frommer, H. Kumar Wickramasinghe, IBM Almaden Research Center.
