Rapid Screening and Detection of Microplastic Particles

Background Myriad kinds of plastics have found their way into our environment, including many that either do not degrade or do so on the time scale of a thousand years. As plastics in the environment are subject to weather conditions, they break down into smaller particles, eventually reaching micron and even nanoparticle sizes. The presence of these...

Photoacoustic Imaging Using a Versatile Acoustic Lens

Applications:Photoacoustic imaging (also called optoacoustic or thermoacoustic imaging) has the potential to image animal or human organs with simultaneous high contrast and high spatial resolution. The photoacoustic signal is small and needs a mechanism to focus it on an image plane without degradation. This technology improves the signal to noise...
