Balancing act: In a new magnetic resonance imaging technique, researchers at IBM use a silicon cantilever to image a tiny sample of calcium fluoride with a resolution of 90 nanometers. The calcium fluoride is deposited on the tip of the cantilever’s thick free end. Credit: IBM Research
Images can be made of calcium-fluoride samples on the cantilever pillars and the distance between the pillars with a resolution of 90 nanometers. The volume of the calcium fluoride is 60,000 times smaller than the volume that conventional MRI microscopy can detect.
