“…This assumption was approved by an assembly with Ni-DNA molecules connected between two gold electrodes using a self-assembly bridging technique developed by Chang and colleagues. This Ni-DNA-gold electrode assembly was visualised and validated by atomic force microscopy [1]. The activity of Ni-DNA as a memristor was demonstrated by its NDR behaviour in response to cyclicvoltage scanning (I-V).…”

“…It is speculated that the resistance of Ni 2+ and Ni 3+ may be different in Ni-DNA [44]. Therefore, the different ratios of Ni ion species in Ni-DNA system may change the effective resistance of the Ni-DNA nanowire device [1]. This external bias-dependent resistance change effect may be recognised as the memory effect of the Ni-DNA system.…”

DNA (deoxyribonucleic acid) is a highly versatile biopolymer that has been a recent focus in the field of nanomachines and nanoelectronics. DNA exhibits many properties, such as high stability, adjustable conductance, vast information storage, self-organising capability and programmability, making it an ideal material in the applications of nanodevices, nanoelectronics and molecular computing. Even though native DNA has low conductance, it can easily be converted into a potential conductor by doping metal ions into the base pairs. Nickel ions have been employed to tune DNA into conducting polymers. Doping of nickel ions within DNA (Ni-DNA) increases the conductivity of DNA by at least 20 folds compared with that of native DNA. Further studies showed that Ni-DNA nanowires exhibit characteristics of memristors, making them a potential mass information storage system. In summary, DNA molecules have promising applications in a variety of fields, including nanodevices, nanomachines, nanoelectronics, organic solar cells, organic light emitting diodes and biosensors.

“…1 Memelements have attracted a considerable amount of attention because of their potential applications in memory computing by storing and processing information on the same physical platform, 2 as envisioned by Feynman in 1959. 3 However, only memristor devices have been developed and characterized, 4,5 while the memcapacitor and meminductor remain to be developed, due to a lack of functional materials or systems whose capacitance or inductance can be controlled by external variables.…”

“…21,24 The ratio of redox species of Ni ions (Ni 2+ /Ni 3+ ) can be changed when the external biases exceed the threshold of redox potential of Ni ions, 4 indicating that the Ni-DNA nanowire may exhibit a capacitive effect. In this study, a micrometer-long Ni-DNA nanowire is developed and characterized to explore its potential in the development of nanowire-based electronic devices.…”

A 2-μm-long Ni ion-chelated DNA molecule (Ni-DNA) was found for the first time to possess both memcapacitor and memristor properties; this Ni-DNA molecule is known as a dual memory circuit element (memelement). As a memelement, the state of impedance on Ni-DNA is proportional to the unit number of Ni ions containing a base pair complex (Ni-bp), which is determined by the previously applied external voltage. Interestingly, the impedances of Ni-DNA change in response to a change in the sweeping frequencies of the external bias. Our simulation results also indicate that changes in the effective resistance and capacitance of Ni-bp may be attributed to changes in the Ni ion redox species in the Ni-bp of a Ni-DNA nanowire. Therefore, the working mechanism of a nanowire-type memcapacitor and memristor is revealed. In summary, the Ni-DNA nanowire is shown to be a multi-dimensional memory device, whose memory state depends on the length of DNA and applied external voltages/frequencies.

Bio‐organisms with various architectures and versatile physiological functions provide a substantial bibliography for electrode design. To elucidate how bio‐organisms and bio‐schemes take effect in advanced electrode materials, this review sorts bio‐assisted construction into two categories, namely, biotemplating synthesis and biomimetic artificial fabrication. The former section summarizes unique characteristics of different biotemplates for electrode preparation, including “bottom‐up” structural designability of biomolecules, metabolism involving, and genetic alterable properties of biological cells, as well as, the structural regularity and integrity of bio‐tissues, with the aim to provide guidelines for manipulating bioarchitectures and endow biotemplating synthesis of electrodes with more designability. The later describes recent efforts in using bio‐prototypes to enhance the essential properties associated with advanced electrodes, including mechanical properties, wettability, mass transport, electron/charge transfer, and catalytic activity, with intensive concerns on the function principles of biomimetic designs in electrochemical systems. Then, advances in applications of bioderived and biomimetic electrode materials are summarized emphasizing how bio‐structures/components and bionic designs help to enhance the charging/discharging and electrocatalytic performance in specific electrochemical energy storage and conversion systems. Finally, future trends with prospects and challenges for developing new bioderived/biomimetic electrode materials, as well as, related conceptual innovation on bionics, are discussed in the last section.
