To enhance the collection efficiency, the vesicles were mixed with gold nanoparticles that were expected to Buffalo PC-MV5DXU2 onto the surface of the vesicles and enhance the scattering of light. The effect of the gold nanoparticles was evaluated according to the time required to collect a certain amount of the vesicles on the glass substrate. In this study, micro- and nanovesicles were collected on a glass substrate via optical pressure.

In a preliminary study, we prepared vesicles with a diameter of 1. When the laser irradiated a suspension of vesicles, the vesicles were accelerated to the propagation direction of the laser beam via a scattering force Buffalo PC-MV5DXU2 were dragged into the center of the beam by its gradient force, which is similar to the process of optical chromatography. These results indicate that the vesicles were collected on the glass surface via the optical pressure, but they were not adsorbed onto the glass surface.

Images of the collected vesicles at different times. The concentration of DPPC, 0.

The images were collected immediately after turning on the laser. Adsorption of the vesicles would be related Buffalo PC-MV5DXU2 their surface charge, which depends on the conditions of the surrounding medium.

According to the literature, 23 the electric charges of phospholipids vary depending on the pH and coexisting ions in the medium. Phosphatidylcholine, for example, is positively charged in an acidic pH lower Buffalo PC-MV5DXU2 3 and then suddenly is negatively charged in water without salts. Conversely, in the presence of NaCl, the charge of the vesicles Buffalo PC-MV5DXU2 gradually and becomes almost neutral in a pH ranging from 3 to 7. Therefore, in deionized water, the vesicles would be negatively charged, resulting in no adsorption on the surface of the hydrophilic substrate because of the electrostatic repulsion.

To fix the vesicles on the glass substrate after turning off the laser, we employed phosphate-buffered saline PBS instead of deionized water to hydrate dipalmitoylphosphatidylcholine DPPC. The increased size of the Buffalo PC-MV5DXU2 can be seen over time. It is obvious that the surrounding medium must contain salts to adsorb the vesicles onto a glass substrate.


The collection speed was decreased with decreases in the concentration of DPPC that corresponded to the number of vesicles. The time required to collect a constant Buffalo PC-MV5DXU2 of vesicles was inversely proportional to the concentration of the DPPC. The time also increased when the size of the vesicles was reduced to nm, even though the required number of vesicles was greater than 1. This fact can be explained by the dependence of the optical pressure on the size of the particle because the intensity of the light on the surface of a particle Buffalo PC-MV5DXU2 with increases in the size of the particle.

Therefore, the collection speed will definitely increase with increases in the power of the laser because the optical pressure Buffalo PC-MV5DXU2 proportional to the power of the laser. The times totaled to 4 min at 0.

Although a time of min is much shorter than what is required for ultracentrifugation that last for more than a day, further improvement in the collection efficiency is preferable for practical applications. Therefore, we attempted to employ gold nanoparticles because these were expected to enhance the light scattering of the vesicles via adsorption onto the surfaces of the vesicles. Time required for collecting a Buffalo PC-MV5DXU2 amount of vesicles at different concentrations of DPPC. Red circle, in the absence of gold nanoparticles and blue circle, in the presence of citrate-coated gold nanoparticles.

The size of the vesicles, 1. We added two different gold nanoparticles, 4-dimethylaminopyridine DMAP -coated and citrate-coated, to a suspension of the vesicles.

These nanoparticles were expected to exhibit different behaviors during adsorption onto the vesicles because DMAP and citrate ions are cationic and anionic, respectively.
