Table 2. Effects of pore size on scaffold properties.

All PDMS scaffolds were fabricated using 90% vol/vol NaCl/PDMS. NaCl crystal size ranges were varied, as indicated below. SEM was used to measure pore size and calculate pore inter-connectivity. Measured porosity was found using wet weight and dry weights, as described in the methods.

NaCl particulate Size Range (µm)	Final Scaffold Volume (mm3)	Measured Pore Size (µm)	Pore Inter- connectivity, %	Measured Porosity, %
53 – 106	32 ± 6	64 ± 8	37	73 ± 0.2
150 – 250	114 ± 19	220 ± 30	67 ± 11	85 ± 0.2
250 – 425	154 ± 5	313 ± 56	67 ± 6	85 ± 0.2
425 – 600	157 ± 11	377 ± 50	74 ± 11	86 ± 0.9
