Only Nanonics can deliver chemicals or gas onto the sample on line, with no need to remove the tip from the sample.

Protein printing is made possible by the Nanonics Chemical Delivery System and Nanopipette

Using any of the Nanonics MultiView systems, chemicals, in liquid or gas form, can be fed into the pipette via a silicon tube. Apart from Protein Printing, applications of this setup include metallic nano-etching and nanolithography: an etchant can be introduced into the sample and scanned across it with nanometer precision using our 3D FlatScanning™ technology. The nanopipette is engaged by the sample using standard contact-mode atomic force microscopy, and our integrated system makes it possible to view the etching simultaneously through any optical microscope.
