Bioengineered protein-based nanodevices with tunable and reproducible memristive performance are fabricated by combining the unique high loading capacity of Archaeoglobus fulgidus ferritin with OWL-generated nanogaps. By tuning the iron amount inside ferritin, the ON/OFF ratio of conductance switching can be modulated accordingly. Higher molecular loading exhibits better memristive performance owing to the higher electrochemical activity of the ferric complex core.
通过将产甲烷八叠球菌铁蛋白的独特高载量与 OWL 产生的纳米间隙相结合，制造出具有可调谐和可重复的忆阻性能的生物工程蛋白纳米器件。通过调节铁蛋白内的铁含量，可以相应地调节电导开关的 ON/OFF 比。较高的分子载量由于铁配合物核心的更高电化学活性而表现出更好的忆阻性能。
