In a few decades human and machine will merge, illness will be eradicated, and human beings will live to 150. Take a journey into the imaginations of scientists and futurists pondering ways to use nanotechnologies, and discussions about how society should or could use them.

Researchers from Australia and Finland have succeeded in building a working transistor, whose active region composes only of a single phosphorus atom in silicon.

Using tiny crystals called quantum dots, researchers have developed a highly sensitive test to detect external chemical modifications to DNA that can be early indicators of cancer.

Israeli scientists have devised a portable breath tester that detects lung cancer. The sensor uses gold nanoparticles to detect chemicals that become more elevated in cancer patients.

The world’s smallest laser has been unveiled. At about 10 times smaller than the wavelength of light, however, this is no ordinary laser, it is the first ever ‘spaser’.

Researchers used tiny nano crystals to develop a highly sensitive test to look for the early warning signs of cancer.
