Title: Microbubbles loaded with nanoparticles: a route to multiple imaging modalities

Authors: Park J, et al.

Journal: ACS Nano, 4(11) pp 6579-6586

Year: 2010

Summary

The researchers developed a method using microfluidics to create bubbles coated with nanoparticles that were stable for a long period of time and had low polydispersity.

Description

Figure 1. Depiction of how bubbles are generated.

The researchers used a microfluidic-centered approach to generating bubbles. A combination of carbon dioxide and insoluble gasses were flowed into a microfluidic channel. The production of bubbles arose from carbon dioxide's solubility in water, which followed Henry's law:
