AI Summary
Summary: Mechanical engineers have developed a platform using sound waves to spin water droplets at high speeds for separating biological particles, potentially leading to new point-of-care applications for precision bioassays and cancer diagnosis with reduced sample volume and damage to delicate exosomes.
Mechanical engineers have devised a diagnostic platform that uses sound waves to spin an individual drop of water up to 6000 revolutions per minute. These speeds separate tiny biological particles within samples placed in a very light disc sitting on top of the spinning drop. The technique could allow new point-of-care applications ranging from precision bioassays to cancer diagnosis. The technique requires less time and sample volume while inflicting less damage to delicate exosomes.
