英文摘要: Abstract(#br)In this work, solid-state electron transport through the three metal core reconstituted ferritins, namely, Mn(III)-ferritin, Co(III)-ferritin, and Cu(II)-ferritin, has been probed and compared to the electron transport via the naturally-occurring iron-containing holoferritin and the metal-free apoferritin using current sensing atomic force spectroscopy (CSAFS), which allows direct contact to be established with the protein molecules. The CSAFS results reveal that by applying compressional force, in varying degrees (17–66nN) and for varying durations (1min, 2min, and 3min), the electronic conductivity of these proteins can be increased (for greater amount of force applied or for prolonged application...
