of the particle size and the materials used in their synthesis. The nanoparticle shape also
contributes significantly to their medicinal properties. Several shapes ranging from oval,
spherical, rods, to teardrop structures may be obtained by chemical methods. Triangular and
hexagonal nanoparticles have been synthesized by using a pine cone extract (PCE). Here,
we report the discovery that PCE, when reacted with silver nitrate ions, yields a high …
