Table 1.
Elemental analysis by EDX where (a) shows percentage by weight and (b) shows percentage by atomic. Elements detected in both POC and BHS scaffolds were carbon, oxygen, and nitrogen with carbon being the most abundant element. Whereas, elements detected in nanocellulose were carbon, oxygen and Sulphur.
