NanoFountainpens™ for Gas or Chemical Delivery

 

Cantilevered and straight nanopipettes can be used as NanoFountainpens™ for controlled chemical delivery to or removal from regions as small as 20 nanometers, thus opening up the world of SPM to unique avenues in nanochemistry. 

NanoFountainpens™ can be provided with multiple channels. However, single channel NanoFountainpens™ can suffice for writing multiple chemicals because they are readily connected to high performance liquid chromatographs which separate chemical species.
