Nanolithography Probes

Nanonics offers capillary glass and quartz nanopipettes for a variety of nanolithographic approaches such as nanoprinting, nanoetching, nanodeposition, etc.  Nanopipettes are capable of both liquid and gas delivery.  These nanopipettes come in a bent geometry suitable for multiprobe operation and integration with an optical microscope (straight nanopipettes are also available).

The nanopipettes can be used with a variety of inks including organic and aqueous liquids, nanoparticles, gases, proteins, nanotubes, and rods.  Controlled deposition can be achieved either through pressure or voltage. 

 


Key Features

Exposed Tip for Optical Integration

    • Provides complete optical access from above and below for full integration with optical and spectral microscopes.
    • Enables controlled and accurate nanolithography at the desired regions and on-line optical and spectral characterization.

 

 

Multiprobe Capabilities

Bent shape and exposed tip enable the inclusion of nanopipette and SPM probes for additional SPM methods conducted within nanometric distance from one each other. Investigate on-line AFM, electrical, thermal, magnetic, and optical characterization of objects or structures generated with a nanopipette.
