An investigation of parameter effect on microcontact printing and feasibility study for application in microelectronic and biomedical

摘要

Microcontact printing (μCP) has been developed about 17 years ago and it is an outstanding surface patterning technique in micron scale and, even in nanoscale. Surface science communities like engineers and biologists have been promoting attention in μCP; therefore they have been rich in improvement to the μCP process itself. However, in order to aim at minimizing some drawbacks of μCP such as a parameter affects, ink-transfer issues and stamp deformation, many studies have been performed recently. In this paper we describe the parameter that affects the performance of printing multiple micro scale lines experimentally, in which are applied load force, uniformity of applied force area, wetness of ink before stamping, ink viscosity and stamp deformation. In this study, we will exhibit the result of graphic inks used for μCP as preliminary study and non-engineered live cells before using functional materials and engineered live cells for the study of cell growth. This is vital prior to enhance the possibility of patterning micrometer or nanometer scale structures with high precision using conductive ink for electronic application.
