When it comes to high-capacity screening tests, or assays, for detecting and targeting certain cells or analytes (substances whose chemical makeup is the goal of identification), the static droplet array (SDA) is an essential and fundamental instrument. One significant technological barrier that prevents the SDA’s wider use is the extraction and collection of target droplets [..]

Virtually applying makeup before completing a purchase or having pterodactyls swoop above in a game are just two examples of how augmented reality and other immersive technologies are changing how we play, watch, and learn.
