| Inkjetting prints fast, flexible circuits |
| July 29, 2011 |
| Spray the right
cocktail through an inkjet printhead, and you can print single-crystal
semiconductors to make fast transistors for flexible surfaces. Inkjet printing of single-crystal films, Nature |

proteins to carbon nanotubes and you have the makings of a lifelike
artificial nose. Biomimetic Chemical Sensors Using Nanoelectronic Readout of Olfactory Receptor Proteins, ACS Nano |
| Paper of Note |
| Batteries get see-through treatment |
| July 25, 2011 |
| Fill a flexible,
transparent material’s microscopic channels with the stuff of
battery electrodes, and you have a bendable, see-through battery.
Pair this battery with see-through circuits, and you can make all
manner of transparent gadgets. Transparent lithium-ion batteries, Proceedings of the National Academy Of Sciences |
| Paper of Note |
| Chemistry promises tomorrow’s computer circuits |
| July 25, 2011 |
| Mix up a batch
of the right super-size molecules and you get networks of intersecting
nanoscale wires. The technique could be used to grow tomorrow’s
computer circuits. Self-assembly of supramolecular wires and cross-junctions and efficient electron tunnelling across them, Chemical Science |
| Paper of Note |
| Carbon nanotube materials made easier |
| July 22, 2011 |
| Confine the right
chemical reaction to to the right places on carbon nanotubes, and
you can keep the nanotubes from clumping together while preserving
the tubes’ useful electrical and optical properties. This makes
it easier to manufacture inexpensive, transparent electronics, including
flexible displays. Confined propagation of covalent chemical reactions on single-walled carbon nanotubes, Nature Communications |

cancer drugs move to the next level: humansA growing number of cancer therapies packaged in infinitesimal particles are making their way to patients.
Can nanotech beat cancer?
Cancer will always be with us in some form, but the fear and devastation it causes could be history within a generation. We'll have the tiniest of things to thank for it.

| "In
most areas of science and technology, the origins of new breakthroughs
can still be found in the work of a small number of people -- or even
a single person -- working at their own pace on their own questions,
pursuing things that interest them. " - Jon Kleinberg, Cornell University |
| "Funding,
of course, enables discoveries but does not guarantee they will occur.
Lack of funding can almost certainly guarantee that discoveries will
not be made." - Ronald Arkin, Georgia Institute of Technology |
| "Physics
is to the rest of science what machine tools are to engineering. A
corollary is that science places power in our hands which can be used
for good or ill. Technology has been abused in this way throughout
the ages from gunpowder to atomic bombs." - John Pendry, Imperial College London |
