The camera is made up of grids of electrical nanowires, cooled to near absolute zero, in which current moves with no resistance until a wire is struck by a photon.
Researchers have created controllable microalgae robots decorated with magnetic nanoparticles that can swim around and actively capture microplastics and nanoplastics from water with over 90% efficiency, offering a sustainable microrobotics solution for reducing plastic pollution.
By analyzing the trajectory of Brownian motion of nanoparticles in liquid using deep learning, researchers were able to identify spherical and rod-shaped gold nanoparticles, which cannot be distinguished using conventional nanoparticle tracking methods, with approximately 80% accuracy for the first time.
