Fabrication of cobalt nanoparticles using Passiflora tripartita var. mollissima fruit extract is an ecofriendly approach; produces various sizes and morphologies, including spherical, hexagonal and triangular. The P. tripartita fruit, known in Ecuador as ?taxo & tumbo? belongs to the Passifloraceae plant family comprises around 530 species originated from temperate and tropical South America. Two different sonication conditions were employed for the synthesis of the cobalt nanoparticles and their growth recorded, in order to analyze the effect of the phytochemical synthesis and the ultrasonic irradiation on the morphology and size of the final product. The synthesized nanoparticles were characterized by U.V.-Vis, Dynamic Light Scattering, Transmission Electron Microscopy (TEM) with Selected Area Electron Diffraction (SAED) and X-ray diffraction. TEM analysis showed polydispersed nanoparticles with size ranges from 110 nm to 10 nm at different time interval and ultrasonic irradiation power. The X-ray diffraction analysis revealed the face-centered cubic geometry and SAED confirmed partial crystalline or amorphous nature of cobalt nanoparticles. Infrared spectrum measurements were carried out to hypothesize the possible biomolecules (flavonoid C&O-glycosides) responsible for stabilization the cobalt nanoparticles using P. tripartita. This simple, ecofriendly, and significantly low-cost protocol can be employed at ease and compatibility for pharmaceutical and biomedical applications.
