Dubbed a &#8220;shadow waveguide,&#8221; the technique uses only two sound sources to create a tightly confined, spatially complex acoustic field inside a chamber without requiring any interior structure. The technology offers a new suite of features to the fast-developing platform of acoustic tweezers that has applications in fields such as chemical reaction control, micro-robotics, drug delivery, and cell and tissue engineering.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2021-08-shadow-waveguide-complex-acoustic-patterns.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">&#8216;Shadow waveguide&#8217; casts complex acoustic patterns to control particles<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Engineers at Duke University have devised a new approach to using sound waves to manipulate tiny particles suspended in liquid in complex ways.
