To prevent water and ice from making our shoes soggy, frosting our car windows and weighing down power lines with icicles, scientists have been exploring new coatings that can repel water. Now one team has developed a way to direct where the water goes when it's pushed away.
Using polymer blends, scientists rapidly generated highly ordered patterns that could be used in the fabrication of microelectronics, antireflective surfaces, magnetic data storage systems, and fluid-flow devices.
Researchers have developed a biosensor that enables creating a range of new easy-to-use health tests similar to home pregnancy tests. The plasmonic biosensor can detect diseased exosomes even by the naked eye.
