anoparticles exhibit completely new or improved

properties with larger particles of the bulk materials and

these novel properties are derived due to the variation in

specific characteristics suchas size, distributionandmorphology

of the particles. Nanoparticles present a higher surface area

to volume ratio with decrease in the size, distribution and

morphology of the particles Recently, synthesis of NPs via eco-

friendly routes have become popular among researchers due

to its low cost, synthesis in ambient atmosphere, non-toxicity,

environmental compatibility etc. and ease of applications as the

resulting particles are highly soluble in water, biocompatible,

and devoid of toxic stabilizers. Among the diverse biosynthetic

approaches, the use of plant extracts has compensation

such as easily available, safe to handle and possess a broad

viability of metabolites. The phytochemicals responsible for

the synthesis of nanoparticles are Terpenoids, flavonoids,

carbohydrates, saponins, alkaloid and protein. In the present

study, Zinc Oxide nanoparticles (ZnO NP) were synthesized

from palm date wood extract (Phoenix dactiferia L.) in a rapid

and eco-friendly microwave-assisted synthesis from zinc nitrate

solution. Microwave parameter (irradiation time), wood extract

and silver nitrate concentration were optimized. The UV–visible

spectroscopy was used to monitor the ZnO NP formation

through sampling at time intervals, phyto-synthesized zinc

oxide nanoparticles dimensions were characterized using

X-ray diffraction analysis. The green synthesized nanoparticles

exhibited potent antibacterial activity against the pathogenic

bacteria, as evidenced by their zones of inhibition and

also a good antifungal activity against the Candida fungus.
