Abstract

Atomic layer deposition (ALD), a gas-phase thin film deposition technique based on repeated, self-terminating gas-solid reactions, has become the method of choice in semiconductor manufacturing and many other technological areas for depositing thin conformal inorganic material layers for various applications. ALD has been discovered and developed independently, at least twice, under different names: atomic layer epitaxy (ALE) and molecular layering. ALE, dating back to 1974 in Finland, has been commonly known as the origin of ALD, while work done since the 1960s in the Soviet Union under the name "molecular layering" (and sometimes other names) has remained much less known. The virtual project on the history of ALD (VPHA) is a volunteer-based effort with open participation, set up to make the early days of ALD more transparent. In VPHA, started in July 2013, the target is to list, read and comment on all early ALD academic and patent literature up to 1986. VPHA has resulted in two essays and several presentations at international conferences. This paper, based on a poster presentation at the 16th International Conference on Atomic Layer Deposition in Dublin, Ireland, 2016, presents a recommended reading list of early ALD publications, created collectively by the VPHA participants through voting. The list contains 22 publications from Finland, Japan, Soviet Union, United Kingdom, and United States. Up to now, a balanced overview regarding the early history of ALD has been missing; the current list is an attempt to remedy this deficiency. (C) 2016 Author(s).

13. Scalable, high performance, enzymatic cathodes based on nanoimprint lithography

Author

Pankratov, Dmitry, Sundberg, Richard, Sotres, Javier, Suyatin, Dmitry B., Maximov, Ivan, Shleev, Sergey, Montelius, Lars, Pankratov, Dmitry, Sundberg, Richard, Sotres, Javier, Suyatin, Dmitry B., Maximov, Ivan, Shleev, Sergey, and Montelius, Lars

Abstract

Here we detail high performance, enzymatic electrodes for oxygen bio-electroreduction, which can be easily and reproducibly fabricated with industry-scale throughput. Planar and nanostructured electrodes were built on biocompatible, flexible polymer sheets, while nanoimprint lithography was used for electrode nanostructuring. To the best of our knowledge, this is one of the first reports concerning the usage of nanoimprint lithography for amperometric bioelectronic devices. The enzyme (Myrothecium verrucaria bilirubin oxidase) was immobilised on planar (control) and artificially nanostructured, gold electrodes by direct physical adsorption. The detailed electrochemical investigation of bioelectrodes was performed and the following parameters were obtained: open circuit voltage of approximately 0.75 V, and maximum bio-electrocatalytic current densities of 18 µA/cm2 and 58 µA/cm2 in air- saturated buffers versus 48 µA/cm2 and 186 µA/cm2 in oxygen-saturated buffers for planar and nanostructured electrodes, respect- ively. The half-deactivation times of planar and nanostructured biocathodes were measured to be 2 h and 14 h, respectively. The comparison of standard heterogeneous and bio-electrocatalytic rate constants showed that the improved bio-electrocatalytic performance of the nanostructured biocathodes compared to planar biodevices is due to the increased surface area of the nanostructured electrodes, whereas their improved operational stability is attributed to stabilisation of the enzyme inside nanocavities.

14. Transparent and flexible, nanostructured and mediatorless glucose/oxygen enzymatic fuel cells

Author

Abstract

Here we detail transparent, flexible, nanostructured, membrane-less and mediator-free glucose/oxygen enzymatic fuel cells, which can be reproducibly fabricated with industrial scale throughput. The electrodes were built on a biocompatible flexible polymer, while nanoimprint lithography was used for their nanostructuring. The electrodes were covered with gold, their surfaces were visualised using scanning electron and atomic force microscopies, and they were also studied spectrophotometrically and electrochemically. The enzymatic fuel cells were fabricated following our previous reports on membrane-less and mediator-free biodevices in which cellobiose dehydrogenase and bilirubin oxidase were used as anodic and cathodic biocatalysts, respectively. The following average characteristics of transparent and flexible biodevices operating in glucose and chloride containing neutral buffers were registered: 0.63 V open-circuit voltage, and 0.6 mW cm-2 maximal power density at a cell voltage of 0.35 V. A transparent and flexible enzymatic fuel cell could still deliver at least 0.5 mW cm-2 after 12 h of continuous operation. Thus, such biodevices can potentially be used as self-powered biosensors or electric power sources for smart electronic contact lenses.

15. Concept for assembling individual nanostructure-based components into complex devices

Author

Suyatin, Dmitry B., Sundberg, Richard, Maximov, Ivan, Shleev, Sergey, Montelius, Lars, Suyatin, Dmitry B., Sundberg, Richard, Maximov, Ivan, Shleev, Sergey, and Montelius, Lars

Abstract

Minute electronic (bio)devices will likely play an increasingly important role in everyday life and beyond, as overall device size often limits device functionality and applicability, a factor especially critical for brain implants. Recent progress in micro- and nanoelectronics has enabled the production of nanoscale electronic components; however, overall device size is often defined by technical and technological limitations, in particular, the ability to combine heterogeneous components made using incompatible processes on different substrates. Here, the authors suggest and evaluate a concept and approach aimed at the direct three-dimensional assembly of individual nanoscale-based components into complex devices for brain implants. They demonstrate this assembly possibility via the transfer of free-standing GaP nanowires, as well as test devices made of gold film which exhibit good quality electrical contacts. The key features essential for such a functional assembly process are discussed. The authors expect this approach to be generic and to enable the development of complex minute electronic (bio)devices based on nanoscale components. The proposed type of assembly may be especially beneficial for devices with strict size constraints, such as implantable neural interfaces.

19. The influence of nanoparticles on enzymatic bioelectrocatalysis

Author

Pankratov, Dmitry, Sundberg, Richard, Suyatin, Dmitry B., Sotres, Javier, Barrantes, Alejandro, Ruzgas, Tautgirdas, Maximov, Ivan, Montelius, Lars, Shleev, Sergey, Pankratov, Dmitry, Sundberg, Richard, Suyatin, Dmitry B., Sotres, Javier, Barrantes, Alejandro, Ruzgas, Tautgirdas, Maximov, Ivan, Montelius, Lars, and Shleev, Sergey

Abstract

In nearly all papers concerning enzyme–nanoparticle based bioelectronic devices, it is stated that the presence of nanoparticles on electrode surfaces per se enhances bioelectrocatalysis, although the reasons for that enhancement are often unclear. Here, we report detailed experimental evidence that neither an overpotential of bioelectrocatalysis, nor direct electron transfer and bioelectrocatalytic reaction rates for an adsorbed enzyme depend on the size of nanoparticles within the range of 20–80 nm, i.e. for nanoparticles that are considerably larger than the enzyme molecules.

Abstract

We present an electrode, based on structurally controlled nanowires, as a first step towards developing a useful nanostructured device for neurophysiological measurements in vivo. The sensing part of the electrode is made of a metal film deposited on top of an array of epitaxially grown gallium phosphide nanowires. We achieved the first functional testing of the nanowire-based electrode by performing acute in vivo recordings in the rat cerebral cortex and withstanding multiple brain implantations. Due to the controllable geometry of the nanowires, this type of electrode can be used as a model system for further analysis of the functional properties of nanostructured neuronal interfaces in vivo.
