pure+curcumin+PCL/PEG, pure+curcumin+PLGA/PEG
samples after day 3,7 and 11 days of culture by MTT assay (n=9).
* denote P values < 0.0001, extremely statistically significant,
** denote P values <0.05, statistically significant,
***denote P value > 0.05, not statistically
significant. Curcumin with PCL-PEG showing statistically extremely significant
difference compared to samples without polymer.
