Albumin grafted coaxial electrosparyed polycaprolactone-zinc oxide nanoparticle for sustained release and activity enhanced antibacterial drug delivery

Zinc oxide-cloxacillin incorporated nanoparticles coated with concentric layers of polycaprolactone and albumin via a coaxial electrospraying technique as an enhanced and sustained antimicrobial delivery system for respiratory infections.

FTIR and XRD of Zinc Oxide Nano Particle from Mangifera indica L. anacardiaceae

Zinc Oxide nanoparticle (ZnO) is broadly used in food packaging industry. Synthesis of ZnO includes different methods like using chemical, gas and sol gel. But it contains more toxins. Hence biosynthesis of zinc oxide nanoparticle is eco-friendly and non toxic. It acts as an anticancer, antidiabetic, antibacterial activity and so on. Trace metals like zinc, magnesium and chromium are involved in glucose metabolism and have a role in controlling blood glucose and hence in diabetic therapy. Zinc is also known to keep the structure of insulin and plays an important role in insulin synthesis, secretion and storage. Nano -ZnO is commonly utilized as additive in food. In this article we discussed about biosynthesis of zinc oxide nanoparticles from Mangifera indica L. anacardiaceae extract. Synthesized nanoparticles is subjected to its characterization such as Fourier Transform Infrared Spectroscopy (FTIR) in the range between 4000cm-1 to 400cm-1 and X-Ray Diffraction (XRD). Functional group was identified in FTIR and nature, size, composition and degree of crystallinity were determined by using X−ray Diffraction analytical technique.

Photocatalytic Degradation of Methylene Blue Dye from Aqueous Solutions in the Presence of Synthesized ZnO Nanoparticles

The photo catalytic degradation of an aqueous solution of methylene blue dye has studied under different conditions of preparation Zinc oxide nanoparticles and study effect of various mass of zinc oxide on the removal of methylene blue dye and initial concentration of MB dye. Several techniques were used to determine the surface properties of the prepared nano-zinc oxide such as XRD, TEM. Results showed that, the phot catalytic degradation process was high at the beginning and then decreased with time. and the phot catalytic degradation efficiency, increased by increasing weight of zinc oxide nanoparticle from 0.05 g to 0.3 g. and decrease with increase weight of zinc oxide nanoparticle from 0.5 g to 0.7g. also showed that the best weight to removal MB dye 0.3 gm.
