“…The temperature-dependent I - V characteristics of devices composed of gold-BPD-Ni 2+ -Ti-gold were studied at temperatures of 50 to 200 K. This study was undertaken to distinguish between transport attributable to molecular phenomena and transport involving metal filaments [ 23 ]. The electron transport mechanism of the crosslinked monolayer of the BPD-Ni 2+ in this nanocrossbar device at temperatures of 50 to 200 K shows a decrease in the current with decreasing the temperature, as might be expected for thermally activated hopping transport [ 24 ].…”

A bottom-up approach was devised to build a crossbar device using the crosslinked SAM of the 5,5′-bis (mercaptomethyl)-2,2′-bipyridine-Ni2+ (BPD- Ni2+) on a gold surface. To avoid metal diffusion through the organic film, the author used (i) nanoscale bottom electrodes to reduce the probability of defects on the bottom electrodes and (ii) molecular crosslinked technology to avoid metal diffusion through the SAMs. The properties of the crosslinked self-assembled monolayer were determined by XPS. I-V characteristics of the device show thermally activated hopping transport. The implementation of this type of architecture will open up new vistas for a new class of devices for transport, storage, and computing.

“…In total, 21 different nitro-substituted OPEs were designed, synthesized and investigated. Recently, nitro-OPE-based molecular devices were fabricated in the cross-bar architecture using a process sequence based on a combination of vaporphase deposition of the molecular layers and standard liftoff patterning for the gold electrodes [83]. This technology enabled the massively parallel fabrication of interconnected, planar nanowell molecular memories.…”

This article reviews the current status and future prospects for the use of nanomaterials and devices in memory technology. First, the status and continuing scaling trends of the flash memory are discussed. Then, a detailed discussion on technologies trying to replace flash in the near-term is provided. This includes phase change random access memory, Fe random access memory and magnetic random access memory. The long-term nanotechnology prospects for memory devices include carbon-nanotube-based memory, molecular electronics and memristors based on resistive materials such as TiO(2).

“…The synthesis of materials in the 1 – 100 nm size range is becoming increasingly important due to the gains offered by their functional tunability, versatility, ability of self-assembly [ 16 , 17 ], and the emergence of novel properties of materials at this length scale [ 18 – 20 ]. Specifically for the case of electrochemical detection systems, nanostructuring of the working electrode through the application of nano-sized modifiers offers attractive new features [ 21 , 22 ]: (1) Nanostructured electrodes, especially those using carbon nanotube and graphene-based materials, exhibit faster electron transfer kinetics due to their extremely high conductivity along particular directions [ 23 ].…”

Nanomaterial-modified detection systems represent a chief driver towards the adoption of electrochemical methods, since nanomaterials enable functional tunability, ability to self-assemble, and novel electrical, optical and catalytic properties that emerge at this scale. This results in tremendous gains in terms of sensitivity, selectivity and versatility. We review the electrochemical methods and mechanisms that may be applied to the detection of neurological drugs. We focus on understanding how specific nano-sized modifiers may be applied to influence the electron transfer event to result in gains in sensitivity, selectivity and versatility of the detection system. This critical review is structured on the basis of the Anatomical Therapeutic Chemical (ATC) Classification System, specifically ATC Code N (neurotransmitters). Specific sections are dedicated to the widely used electrodes based on the carbon materials, supporting electrolytes, and on electrochemical detection paradigms for neurological drugs and neurotransmitters within the groups referred to as ATC codes N01 to N07. We finally discuss emerging trends and future challenges such as the development of strategies for simultaneous detection of multiple targets with high spatial and temporal resolutions, the integration of microfluidic strategies for selective and localized analyte pre-concentration, the real-time monitoring of neurotransmitter secretions from active cell cultures under electro- and chemotactic cues, aptamer-based biosensors, and the miniaturization of the sensing system for detection in small sample volumes and for enabling cost savings due to manufacturing scale-up. The Electronic Supporting Material (ESM) includes review articles dealing with the review topic in last 40 years, as well as key properties of the analytes, viz., pKa values, half-life of drugs and their electrochemical mechanisms. The ESM also defines analytical figures of merit of the drugs and neurotransmitters. The article contains 198 references in the main manuscript and 207 references in the Electronic Supporting Material.FigureᅟElectronic supplementary materialThe online version of this article (doi:10.1007/s00604-014-1308-4) contains supplementary material, which is available to authorized users.
