Piezoelectric Inkjet Printing of Biomimetic Inks for Reactive Surfaces

Dendrimer printing: A composite dendrimer ink is developed and patterned onto gold, glass, or sapphire substrates using piezoelectric inkjet printing. Varying the spot spacing, the number of print cycles, and the reaction time with monosilicic acid (see image) provides a microenvironment with properties reminiscent of patterned silica on the cell wall of diatoms.
