Researchers from Duke University have developed a new type of “acoustic tweezers” that can manipulate tiny objects in a Petri dish without hand. Such systems are usually very complex and have not been widely used. The researchers hope to commercialize their system by making it simple and affordable. < / P > < p > the system uses sound waves to move particles and other tiny things, such as cells, without requiring scientists to physically manipulate them. Using sound waves in this way is not a new idea, but until now, such a system requires a lot of equipment and training of the researchers who use them. The system developed by Duke University is expected to lower the entry threshold. < / P > < p > the ability to control and manipulate objects in things like Petri dishes without actually touching them removes an important factor from the equation, which is helpful for researchers who want to get the most accurate results. “Acoustic tweezers” solves this problem, but it has always been a challenge to build a user-friendly and simple system. < / P > < p > “recent advances have led to many advanced, versatile tools,” Tony Jun Huang, co-author of the study, said in a statement. “At the end of the day, however, success in this field depends on the willingness of end users such as biologists, chemists or clinicians to adopt the technology. This article shows a step towards a more user-friendly workflow that makes it easier for end users to adopt this technology. ” < / P > < p > using sound waves to manipulate tiny things is actually quite simple, at least on paper. By applying sound waves to both sides of a chamber, sound waves can actually organize small objects into groups or “nodes.”. It’s a very rudimentary way to move particles around the plate, but additional advances have made it possible to use sound waves to create different patterns on the plate, allowing the particles to be manipulated to new locations without hand, and even to gather all the particles on the plate in one place. < / P > < p > “the aim of this study was to replicate some of the functions of our previous acoustic tweezers in a Petri dish,” the researchers explained. “Our next goal is to build a single prototype that implements all the capabilities of these three settings, if not more.” IPhone 12 whole family barrel model exposed: it’s a tribute to iPhone 4
