Nanoscale Engineering"Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications."

(U.S. National Nanotechnology Initiative: www.nano.gov)

Therefore nanoscale engineering is the design, analysis, and/or construction of materials containing nanostructures.

Piezoelectric Ink Jetting Biological MaterialsAre there obstacles?

• Often aqueous solutions– High surface tension – Water = 72.8 dynes/cm

• Low viscosity – 0.89 – 3.00 centipoise

• “Friendly”surfactants?– CMC

Self-Assembling Biomaterials• Length scale

– Atoms (10-10)– Molecules (10-10-10-9) – Polymers (10-9)– Viruses (10-8)– Cells (10-5)– Multicellular organisms (10-5-101)

• Polymers– DNA – RNA– Proteins– Lipid bilayers self-assemble into membranes– Higher level organization (protein insertion into

membrane)– Trafficking– Extracellular matrices– Support structures (skeleton, teeth, antlers, husks)
