Spot Nanoparticles

There is a growing interest in detecting nanoparticles and nanotechnologists are racing to build devices that can detect and characterise these particles. One method is having resonating devices that changes when a nanoparticle is bounced off the surface, measured by a laser. However this method is only ideal in certain cases and positions. Researchers from Washington University have a new vibrating micro-mushroom device that promises greater reliability in detecting nanoparticles.
