Assistant Professor Sushant Anand of MIE and his research associates have taken their research to a new level by creating ultra-small (100-400 nm in sizes) nanoemulsions formed by self-assembly of nanoparticles around droplets.
Anand and his team have developed a single-step technique for creating nanoemulsions that are faster, more energy efficient, and smaller.
“Nanotechnology has a huge role to play in dealing with many problems in today’s time,” Anand explains. “Take oil-water emulsions as an example. Going ‘nano’ with droplet sizes can make a huge difference in the shelf-life of many emulsion-based products like cosmetics, food products, drug delivery, and many multi-billion dollar industries.”
Anand added, “Typically surfactant molecules are used to prevent drops from coming together. But such molecules can have adverse effects in many cases. So, there is a growing interest in making surfactant-free nanoparticle stabilized emulsions.”
In order to create emulsions in a traditional way, a very high particle concentration is needed to make small nanoemulsions.
As the director of the Anand Research Group laboratory at UIC, Anand says “Our technique is very scalable and can potentially be used on an industrial level. We have shown that it is highly energy efficient when compared to current techniques of making emulsions, and we were also able to provide a framework on the different factors that control the size of emulsions.”
The newly discovered technique prepares new gateways and opportunities, from making membranes to drug delivery applications.
Additionally, Anand and Dong Jin Kang, a postdoc working under his directorship, has developed a new way to make simple and complex nanoparticles. This project is noted in a related work that has recently appeared in the journal Nanoscale, titled Nanoparticle Synthesis Via Bubbling Vapor Precursors in Bulk Liquids.
