“…Thus, it can be considered that the present positioning accuracy is on the order of 3 µm. In order to further control the arrangement of these CNT-bundles, specifically to interrupt some of them, one possible approach is to employ a high-speed AFM nano-manipulator coupled with a haptic device [ 34 ] to modify the CNT-network mechanically.…”

Carbon nanotubes (CNTs) are ultimately small structures, attractive for future nanoelectronics. CNT-bundles on Si nanostructures can offer an alternative pathway to build hybrid CMOS-compatible devices. To develop a simple method of using such CNT-bundles as transistor channels, we fabricated semiconductor single-walled CNT field-effect transistors using inkjet printing on a CMOS-compatible platform. We investigated a method of producing stable CNT solutions without surfactants, allowing for CNT debundling and dispersion. An inkjet-printing system disperses CNT-networks with ultimately low density (down to discrete CNT-bundles) in Al source-drain gaps of transistors. Despite the small number of networks and random positions, such CNT-bundles provide paths to the flow current. For enhanced controllability, we also demonstrate the manipulation of CNT-networks using an AFM technique.

“…Such high conductivities will clear the path to move away from using conducting substrates—which will make fabricating electronic components a challenge—and lead to a much greater magnitude of difference in conductivity between the LEB and ES states. Likewise, increasing the resolution and write‐speed of the process through the use of sharper tips and incorporation into high‐speed AFMs, as has previously been demonstrated with AFM oxidation of silicon, will allow application of this technique. Areas under current consideration for further exploration include detailed electrochemical studies (also on larger patterned areas), careful exploration of a variety of operating conditions to ensure wide applicability, and controlled fabrication of fundamental electronic components such as nanoscale diodes and transistors.…”

local-oxidation nanolithography techniques. [ 17,18 ] This constructive c-AFM redox-writing (cAROW) methodology shows potential for further exploration and development into a scalable, fast write-read technology. [ 19,20 ] The organic semiconductor used in this investigation is based on phenyl/amine-capped tetra(aniline), Ph/NH 2 -TANI , a short-chain, functional, and well-defi ned low molecular weight oligomeric analogue of the well-known conducting polymer, poly(aniline), PANI. Ph/NH 2 -TANI retains the desirable optoelectronic properties of PANI while circumventing the issues of poor solubility, processability, and polydispersity that have previously limited the applications of the polymer. [ 21 ] It is possible to fi ne-tune the optoelectronic properties of tetra(aniline) derivatives, and higher oligomers, simply through modifi cation of the central unit and variation of the end-group functionalization. [ 22 ] Similar to PANI, these oligomeric materials can be reversibly switched (doped) from their conductive emeraldine salt (ES) state to either the nonconductive fully reduced leucoemeraldine base (LEB) or emeraldine base (EB) states through redox, and acid-base chemistry, respectively. [ 23 ] An extensive range of possible inorganic and organic acid dopants exists, with the latter able to simultaneously act as dopants and plasticisers.In this work, N -(4-(((1E,4E)-4-((4-(phenylamino)-phenyl) imino)-cyclohexa-2,5-dien-1-ylidene)amino)phenyl)octanamide ( TANI-C 8 ) doped to the conductive ES state with the prototypical PANI dopant camphorsulfonic acid ( CSA ) was chosen, as this combination formed smooth, continuous thin fi lms on highly oriented pyrolytic graphite (HOPG). Unlike EB-state TANI -based materials, [ 24 ] fi lms prepared from ESstate TANI-C 8 (see the Experimental Section for details) The atomic force microscope (AFM) has developed into a mature and widespread topography characterisation tool since its inception in the 1980s. The high resolution and precision nature of this tool has also led to widespread use, under ambient conditions, for diverse applications. These applications include the direct observation of single-molecule events, [ 1,2 ] molecular force measurements, [ 3,4 ] the fabrication of nanostructures via a variety of nanoscale lithographies, [ 5,6 ] including electrochemical deprotection to yield responsive monolayers, [ 7,8 ] enzymatic oxidative poly merization to locally form conducting polymers, [ 9 ] formation of polymerized sulphur nanostructures, [ 10 ] and direct writing of metallic nanostructures. [ 11 ] These applications were recently classifi ed into mechanical, thermal, diffusive, and electrical processes according to the dominant tip-surface interaction involved. [ 12 ] The last includes probe-based oxidation and reduction lithographies. Although oxidative processes are known, and have been exploited extensively, [13][14][15] reductive processes under ambient conditions are less common.Here we show, in a facile single-step approach, reversible local reductive and oxida...

It is also possible to use the AFM as a physical micromanipulator in force nanoindentation studies to map the mechanical properties of viruses in uncoating and capsid interaction studies [ 95 , 96 ] and there exists a modification of force spectroscopy using hybrid binding domain functionalised AFM cantilevers to investigate and quantify the in situ hybridization of miRNA and other nucleic acids in single cells [ 97 ].…”

Visualization of algal viruses has been paramount to their study and understanding. The direct observation of the morphological dynamics of infection is a highly desired capability and the focus of instrument development across a variety of microscopy technologies. However, the high temporal (ms) and spatial resolution (nm) required, combined with the need to operate in physiologically relevant conditions presents a significant challenge. Here we present a short history of virus structure study and its relation to algal viruses and highlight current work, concentrating on electron microscopy and atomic force microscopy, towards the direct observation of individual algae–virus interactions. Finally, we make predictions towards future algal virus study direction with particular focus on the exciting opportunities offered by modern high-speed atomic force microscopy methods and instrumentation.
