The ones we used are 10 micrometers in diameter, a similar size to biological cells. For comparison, a typical human hair is 100 micrometers in diameter.</p><p>The interesting thing about these liquid droplets are that they have a solid skeleton embedded inside them, hence the name endoskeletal droplets. There are different types of endoskeletal droplets but the ones we study in this project have a disk-shaped solid inside the liquid droplet.</p><div class="ucb-box ucb-box-title-hidden ucb-box-alignment-right ucb-box-style-fill ucb-box-theme-white"> <div class="ucb-box-inner"> <div class="ucb-box-title"></div> <div class="ucb-box-content"><p><br> </p><div class="imageMediaStyle medium_750px_50_display_size_"> <img loading="lazy" src="/mechanical/sites/default/files/styles/medium_750px_50_display_size_/public/article-image/fig_1.png?itok=_TpfmCCY" width="750" height="263" alt="figure 1"> </div> <br>The disk-shaped endoskeletal droplets and their freedom of rotation inside the droplet.</div> </div> </div><p><strong>What are the real-world impacts from this research? How will the collaborative work benefit society?</strong></p><p>The radiation forces are very important in any colloidal system that deals with acoustic waves. For example, these forces are being studied currently for cell separation for disease diagnosis or optimizing drug delivery systems for cancer treatments. But these forces and their behaviors in multiphase colloidal systems have not yet been fully understood. With this current paper, we have gotten a better understanding of the primary and secondary radiation forces.</p><p>Moreover, this study demonstrated the possibility of manipulating internal structures of droplets and cells. This can pave the way to manipulating internal organelles in a cell, which is very challenging for current techniques, but could be helpful to understand the communication and function of intracellular organelles.&nbsp; &nbsp;</p><p><strong>Is exploring the internal structure of a droplet this small challenging? </strong></p><p>It is very challenging because the internal structure adds a lot of complexity. With that added internal phase, which has different physical and chemical&nbsp;properties, it is very hard to properly explore the behavior of the internal structure.</p><p>I think the geometry also played an important part.
