SOLVENT STUDY ON MICRO TOWERS FABRICATED VIA MAP
Publication or External Link
Common microfabrication techniques haven been briefly reviewed and a detailed description of multiphoton absorption polymerization (MAP) ranging from its history, specific experimental setup, and resolution to its applications and drawbacks has also been given. A fast method to fabricate micro towers via MAP has been found. Towers with diameters ranging from 900 nm to 6 microns were fabricated and the best aspect ratio (~40) does not change with the diameter of the towers. Different solvents were used to dry those towers and we found that surface tension is not the only factor that leads to lower aspect-ratio.
