Alamar Blue cell absorbance properties of PEG-impregnated BA scaffolds (a – PEG-D900, b – PEG-D1000, c – PEG-M900, d – PEG-M1000, e – PEG-P900 and f – PEG-P1000), control and blank at wavelengths of (A) 570 nm and (B) 600 nm.

Note that the absorbance values increases significantly (p<0.001 for both wavelengths) with culture time from day 1 to day 7 at lower wavelength.
