Physics and Medicine combine forces to investigate the hidden toxicity of nanoparticles. Two researchers - a doctor and a physicist - from the University of Leicester analyze with the financial support of the Engineering and Physical Sciences Research Council the possible toxic damage derived from the inhalation of nanoparticles used daily for various purposes.
The small size of the nanoparticles with a size range of about 5-100 nanometers provides many novel and useful properties, being used in applications as diverse as face creams, medical imaging, novel drug therapies and magnetic recording.
Such particles are increasingly being manufactured and released into the environment on an industrial scale. However, there is growing concern that the same properties that make them useful also enhance the toxicity of the particles we breathe.
These particles are so small - 100,000 particles only span a few millimeters - that it is unclear how the normal defenses of the human body could cope with them.
