The SEM analysis of aluminium-potassium hybrid nanoparticles synthesized using P. longifolia leaves extract as shown in figure , shows that the particles have an average diameter ranging from 70 to 103 nm calculated according to the method used by . The nanoparticles are predominantly spherical but exhibit a non-uniform distribution and slight agglomeration. These observations are consistent with findings in related studies and can be explained by several factors. The spherical shape of the nanoparticles is a common characteristic in biogenic synthesis. The Energy Dispersive X-ray (EDX) analysis of aluminium-potassium nanoparticles synthesized using P.
