World's smallest transistor built with just 7 atoms.

Scientists have literally taken a leap into a new era of computing power by making the world's smallest precision-built transistor - a "quantum dot" of just seven atoms in a single silicon crystal. Despite its incredibly tiny size - a mere four billionths of a metre long - the quantum dot is a functioning electronic device, the world's first created deliberately by placing individual atoms.

It can be used to regulate and control electrical current flow like a commercial transistor but it represents a key step into a new age of atomic-scale miniaturisation and super-fast, super-powerful computers.

The discovery is reported today in the journal Nature Nanotechnology by a team from the UNSW Centre for Quantum Computer Technology (CQCT) and the University of Wisconsin-Madison.

"The Australian team has been able to fabricate an electronic device entirely out of crystalline silicon where we have replaced just seven individual silicon atoms with phosphorus atoms.

World's smallest and lightest telemedicine microscope, of the size of a large egg, has been developed, which may help improve healthcare in developing countries.

"This is a very capable and yet cost-effective microscope, shrunk into a very small package and weighing only 46 grams," said the inventor of the Aydogan Ozcan from the University of California, Los Angeles.
