Young's modulus and thickness measurements for scaffolds

Scaffold type	Avg. E (MPα)	No. of samples	Avg. no. of spots/sample	Avg. no. of measurements/spot	Avg. Thickness (μm)
	Mean ± Std. dev. of Mean
PLGA Nanofibers	11.0 ± 3.3†	3	4	66	1.2 ± 0.1*
PLGA Microfibers	0.30 ± 0.03	3	3	55	12.1 ± 1.5*

PLGA, Poly-(DL)-lactide-co-glycolide

^†no statistical difference, between spin-coated film and nanofibers, p>0.05, ANOVA with Bonferroni's posthoc test.

^*Values represent fiber mat thickness only and do not include thickness of the underlying solvent cast film layer
