Fluorescent dyes have been transferred through 100 nm diameter pores:

• Rhodamine (6-TAMRA)
• Alexafluor 488 (Mol. Probes)

There is electrical evidence of printing:

• I ~ u (fluid flow through nanopore) as shown in the graph indicate increasing flow rates and a saturation at higher electrode biases.

Other printing inks are being tested in the toolbit:

• Quantum Dots (Mol. Probes)
• Nanoparticles - polystyrene (Mol. Probes)
• Fluorescein
