In a study recently published in the journal Small, researchers from Nano Life Science Institute (WPI NanoLSI), Kanazawa University, Japan, collaborating with Professor Sarikaya, Seattle, U.S., used frequency modulated atomic force microscopy to reveal the molecular architecture of genetically designed and point mutated peptides and their self-organizations each forming single-molecule thick, distinct biological crystals on atomically flat graphite and MoS2 surfaces, offering a potential platform for hybrid technologies such as bioelectronics, biosensors, and protein arrays.
