One of the predominant features of nano-materials is an extremely high surface area. Emerging Science joins Chris Landry, professor of chemistry at the University of Vermont, as he describes how nanotechnology applications are improving the efficacy of cancer drugs by delivering more medicine to patients. |

There's only one source of renewable energy that can provide all of the world's needs and that's the Sun. In fact, enough sunlight falls on the Earth's surface in just a couple of hours each day to meet the whole world's energy needs for one year. The question is: how can we effectively and economically harness this solar energy, without mass-producing very expensive conventional solar cells, which would ultimately require vast tracts of land in order to do their job? Nanotechnology could provide the answer in the form of a new kind of solar cell, one which would be relatively inexpensive to manufacture and highly flexible in design. In fact, you maybe surprised as to just how flexible these cells might be! Find out more by watching this movie. This is one of a selection of intriguing movies which are available for free download from the EPSRC Nanotechnology Image Library at : www.nanoscience.dept.shef.ac.uk You may also be interested in navigating to the "Soft Machines" site belonging to Professor Richard Jones - who features in this movie - for up-to-date discourse on all things nano.

Running shoes are designed to absorb energy, to make them comfortable and protect your feet. To do this they have to be soft and squishy, but if you walked on a soft material it would flatten out, getting deader and deader as you went through the day. To stop this, we need to add hard bits to the formulation. These prevent the shape squishing too far, and allow it to rebound after each step. As a result, the running shoe stays in shape. The nanotechnology comes in because the soft and the ... |

Approximately 99 per cent of medicinal molecules don't reach their targets and subsequently, stay in the body of the patient. As these molecules can sometimes be very toxic - particularly in the case of those designed to target cancers - research is being undertaken into more effective ways of safely transporting and delivering drugs. A challenge for nanotechnology in this research is to create a device which can carry a drug payload to it's target, be monitored throughout it's journey and deliver, without being attacked and destroyed by the body's natural defences. This calls for something which possesses stealth design characteristics and a plausible device is described here in this movie. This is one of a selection of intriguing movies which are available for free download from the EPSRC Nanotechnology Image Library at : www.nanoscience.dept.shef.ac.uk You may also be interested in navigating to the "Soft Machines" site belonging to Professor Richard Jones - who features in this movie - for up-to-date discourse on all things nano.
