SpletWhen comparing tube formation on agarose and PDMS molds with similar stiffness, i.e., agarose 3% vs. PDMS 1:30 (439.9 kPa and 680 kPa, respectively) and agarose 5% vs. PDMS 1:20 (1388.2 kPa and 1440 kPa, respectively), significant differences were observed for the formation of 1N, 1P, and 3P tubes. These differences suggest that the composition ...
