Interface molecular environment adjustments play an important role in the analytical device design. The creation and well controls of chemical patterns are therefore crucial when generating a supporting matrix suitable for diverse analytical tools. Different from most fabrication techniques, chemical lift-off lithography (CLL) builds a straightforward bridge between chemical pattern generation and analytical device fabrication. This approach relies on a direct molecular pattern creation on supporting substrates, and the accompanying produced unique interface environment benefits the group of analytical devices. An alkanethiol self-assembled monolayer is ruptured in this CLL operation, generating randomly distributed artificial molecular defects for substrate property modification with diverse functionalities. Important analytical concepts such as functional probe anchoring, microscopic strategies, high-throughput microfluidics, and spectroscopic techniques can all be integrated with this approach. Direct connections between functional chemical patterns and practical devices are accordingly built with this convenient route.
