Nano-patterning method for molecularly imprinted polymers

Nano Fountain Pen (NFP) uses hollow glass or quartz capillaries heat-drawn to a tapered tip with an aperture of a few hundred nanometers26.

When pre-polymerization solution is loaded in such nano-pipettes, it is drawn to the end of the tapered tip by capillary forces, however the solution will flow out only upon contact with the surface.

The nano-pipette is mounted as the probe of an AFM and can be controllably directed to very precise locations on a surface, using the regular control of an AFM probe.

When loaded with MIPs pre-polymerization mixture, the NFP printing results in drops as small as ~ 100 nm in diameter, which are subsequently polymerized by UV radiation. This yields arrays of nanometre-sized MIPs.
