Phospholipids have been widely investigated for the preparation of liposomes, and micro and nanobubbles.They comprise biocompatible and biodegradable molecules and offer simple preparation with a variety of functions in diagnostic and therapeutic applications.Phospholipids require emulsifiers and surfactants to assemble in the form of bubbles.These surfactants determine the size, zeta potential, and other characteristics of particles.

Polyethylene glycol click here (PEG) and its various derivatives have been employed by researchers to synthesize micro and nanobubbles.The stability of phospholipid-shelled nanobubbles has been reported by various researchers owing to the reduction of surface tension by surfactants in the shell.Nanobubbles have been employed to deliver oxygen to tissues and hypoxic cells.In this study, we investigated the effects of different ratios of phospholipids to PEG on the size, distribution, and characterization of oxygen nanobubbles (ONBs).

ONBs were synthesized using a sonication technique.We analyzed and compared the sizes, numbers of generated particles, and zeta potentials of different compositions of ONBs using dynamic 2014 dodge ram 1500 fender flares light scattering and nanoparticle tracking analysis.Then, we employed these oxygen nanobubbles to enhance the cellular microenvironment and cell viability.ONBs were also investigated for ultrasound imaging.
