Amyloid-like insulin fibers acquired in fluid using iDrive, a special cantilever holder that uses Lorentz Force to magnetically actuate the cantilever. The fibers were formed by first incubating bovine insulin at 80°C for 48 hours then maintaining them at room temperature for continued fiber growth. The left-handed nature of the fibers is clearly visible. 3 µm scan (left) 500 nm scan (right).
