Positron Annihilation Study of ZnO Nanoparticles Grown Under Folic Acid Template

Despite manifold interests on the wide band gap (3.37 eV) semiconductor properties of zinc oxide (ZnO) material and its varied optoelectronic applications [1,2], much remains to be explored when its material perspective is sought in the context of nanotechnology and biomedicine. ZnO is generally known to be nontoxic and biocompatible substance [3]. It is also realized that ZnO nanomaterials with the size dependent surface properties hold considerable promise as anticancer agent; the area is sensitive and important to biomedicine [4]. The field eventually leads to versatile platforms for biomedical applications and therapeutic intervention.
