Two-Component Graded Deposition of Biomolecules with a Double-Barreled Nanopipette


  • This work was funded by the BBSRC, and the Winston Churchill Foundation provided a studentship to K.T.R.

Pretty as a picture: The printing of highly complex graded images with two different species (see picture) has been developed through the use of double-barreled pipettes. This method of submicron deposition of biomolecules eliminates registry problems that are inherent to other deposition techniques.
