A Chitin Nanofiber Ink for Airbrushing, Replica Molding, and Microcontact Printing of Self-assembled Macro-, Micro-, and Nanostructures

A chitin nanofiber ink affords facile fabrication of chitin macro- and nanostructures through airbrushing, replica molding, and microcontact printing. Self-assembled chitin nanofiber structures with sub-50-nm features are produced on extended areas.
