  • Rock ‘n’ Roll nanotubes
    Nanotubes and nanowires are not as amenable to manipulation as macroscopic commodities, however, their promise as building blocks for future electronics, sensors, and electromechanical devices, means that researchers are keen to find ways to handle these tiny entities easily.
  • How much risk do people think there is in nanotechnology?
    There has been a huge upsurge in anticipating how the public will react to nanotechnology, particularly a widespread negativity about its use and the possible health risks associated with nanomaterials.
  • Sounding out molecular control
    Tweezers are not just for plucking eyebrows and removing splinters, they can be used to arrange small objects.
  • Nanoparticles and living cells
    New approaches and standardized test procedures to study the impact of nanoparticles on living cells are urgently needed for the evaluation of potential hazards relating human exposure to nanoparticles.
  • Bend it, stretch it!
    It has been known for some time that stretchability properties in materials will significantly expand the scope of applications in the electronics industry particularly for large-area electronic displays, sensors and actuators, and unlike conventional devices stretchable electronics can cover arbitrary surfaces and movable parts, opening up a wealth of opportunities.

  • To tweet or not to tweet
    Posted by Jonathan Agbenyega • 04 February 2010
    I spotted this tweet recently, and it got me thinking... Which is a better barometer of opinion: Tweet or Taxi driver? Are we placing too much emphasis on networking via the internet when a simple f...

  • Nanofabrication by self-assembly Nanofabrication by self-assembly
    The self-assembly paradigm in chemistry, physics and biology has matured scientifically over the past two-decades to a point of sophistication that one can begin to exploit its numerous attributes in nanofabrication. In what follows we will take a brief look at current thinking about self-assembly and with some recent examples taken from our own work examine how nanofabrication has benefited from self-assembly.
  • Nanofabrication by DNA self-assembly Nanofabrication by DNA self-assembly
    Molecular self-assembly strategies involve the formation of nanometer scale objects and materials in the absence of significant external control. One increasingly popular self-assembly approach makes use of the unique properties of deoxyribonucleic acid (DNA) including its diminutive size and high capacity for information storage. For many applications, DNA stands alone as the top choice for the programmable construction of supramolecular materials due to its specific and well-understood base-pairing interactions. In this review, we will discuss recent advances in the fabrication of materials via DNA based self-assembly.
  • Directed assembly of nanowires Directed assembly of nanowires
    Nanowires of a diverse range of compositions with tailored physical properties can be produced through synthetic means. These structures have been used as key components in flexible electronics, electronic logic gates, renewable energy technologies, and biological or gas sensing applications. Integrating these nanostructures into device or technology platforms will complement existing nanofabrication procedures by broadening the types of nanostructured materials that are utilized in device fabrication. This integration requires an ability to assemble these nanowires as controllable building blocks. Techniques are being developed that can quickly manipulate large quantities of nanowires through parallel processes.
  • Functional hybrid materials Functional hybrid materials
    Nanofabrication via self-assembly of hybrid materials into well-defined architectures is essential for the next generation of miniaturized devices. This paper describes our group's achievements towards the development of multifunctional nanostructures via self-assembly of hybrid systems based on the block copolymer PS-b-P4VP and inorganic nanoparticles (NPs) into 0D, 1D, 2D and complex 3D periodic nanostructures. The morphologies of these architectures are adjusted to gain functions via structural control at different dimensions.

  • Semiconductor nanowire devices
    In the past ten years the idea of using self-assembled nanostructures to overcome the limitations of top-down fabrication approach was the driving force behind the tremendous interest in semiconducting nanowires and nanotubes.
  • Carbon nanotube-based neat fibers
    Macroscopic fibers containing only Carbon NanoTubes (CNTs) will yield great advances in high-tech applications if they can attain a significant portion of the extraordinary mechanical and electrical properties of individual CNTs.

    Theoretical van der Waals gloves could generate an adhesion force comparable to the body weight of 500 men.
  • Nanoparticle-modified polyelectrolyte capsules
    The concept of polyelectrolyte capsules as multifunctional carrier systems is described. The walls of a capsule can be functionalized with fluorescent, magnetic, and heatable colloidal nanoparticles and also biological macromolecules, while its cavity can be loaded with cargo molecules. Potential applications of this carrier system for delivery and sensing in cells are discussed.
  • Self-assembling peptide nanotubes
    Biological proteins and peptides have the intrinsic ability to self-assemble into elongated solid nanofibrils, which may give rise to amyloid diseases or inspire applications ranging from tissue engineering to nanoelectronics.
