C nanoparticle patterning

A solution was prepared by putting 0.015 g of carbon nanoparticles into 20 mLof ethanol with 10 µL of surfactant added. The solution is not transparent when viewed under room light. Lever #3 of the 11-07-05 set was employed to pattern a gold substrate. Experimental data are as follows.

• 3x3 [32, 16, 8s] @ (-40, -30); 79°F, 79% >> no pattern
• Retry: 3x3 [32, 16, 8s] @ (-40, -20)

Laser was moved to lever #4 because the reflection on lever #3 did not provide a good signal on the photodiode. Experimental data are as follows.

• 3x3 [32, 16, 8s] @ (-40, -40) and (-20,-40)
• 3x3 [32, 16, 8s] => 4x4 @ (0,-40)
