Details

Overview

– Nanoink Nscriptor
– Direct writing of molecules on surfaces
– Bottom-up fabrication
– < 1µm patterning from supplied design
– Integrates with photolithography processing

Benefits of the Dip-Pen Nanolithography (DPN)

Higher resolution/finer structures (sub- 100 nm) than traditional printing methods
Selective patterning of different molecules at different sites on surface
DPN allows multiple patterning at multiple scales/shapes/sizes
Applications:
Biosensors
Cell engineerin

Technical features and specifications

Uses experimental set up of Atomic Force Microscopy (AFM)
Three main components of DPN:
– AFM-tip as “pen”
– Sample surface as “paper”
– Molecular chemicals with affinity to surface as “ink”
Molecules (ink) transported from tip to surface via capillary transport trough formed water meniscus
