Fig. 1. Workflow and timeline of UV-patterning approach compared to traditional micromolding.

This schematic overview shows the steps required for designing and fabricating patterned gelatin substrates start-to-finish using traditional micromolding (top) or UV-patterning (bottom) fabrication. Micromolding involves a 5-time step sequence of interdependent steps, compared to a 2-time step process using UV-patterning. This 60% faster work flow is possible because UV-patterning eliminates the photolithography steps enabling separation and parallelization of work steps, such as pattern design and gelatin film fabrication.
