Thanks to the rapid progress in tiny tech, we've been mainly using microfluidics to sort tiny particles by size. But now, there's a new way to sort them by shape, which could be a big deal for medical tests and chemistry. A recent study introduces a new method using sound waves to separate oddly shaped particles from round ones without needing any labels. This breakthrough could lead to better ways to deliver drugs or diagnose diseases by offering a smarter approach to sorting these tiny particles.
