2.3 Morphological Study
The morphology of the nanocomposite hydrogel with phomopsidione was
observed under the scanning electron microscopy (SEM) and transmission
electron microscopy (TEM). The surface morphology of the nanocomposite
hydrogel was observed under SEM (Jeol 6010Plus). For TEM observation,
the sample was stained using uranyl acetate and placed on a copper grid.
The sample was then examined using TEM (Phillips CM12), operating at 120
kV.
