C-Crete, a startup company that makes a nano-engineered cement, has won $120,000 in the school's Entrepreneurship Competition. C-Crete's cement is reportedly stronger than any extant cement, and reduces CO2 emissions. Runners-up included makers of a nano-engineered insulin chewing gum and a silent alarm clock that was not nano-engineered.
Nanotech has opened the door to some serious sci-fi possibilities: tiny robots -- built by other tiny robots -- that swim in our bloodstreams eradicating infection or hunting tumors, or perhaps assembling miniscule electronic components. But programming such tiny objects to do what we want presents a problem: commands need space to exist, and space is limited aboard a nanobot. But two papers just published in the journal Nature today highlight an interesting and promising approach to this problem: embedding the commands in the nanobots' environments.
Researchers in UCSD's engineering department are taking lasers to new lows, demonstrating a micron-scale laser measuring less than one-thousandth of a millimeter per side. And while sub-wavelength lasers have been demonstrated in the past, the UCSD team did it without cryogenically cooling their gear to extremely low temperatures; their tiny laser pulses away at room temperature, making it the smallest laser to do so and paving the way for practical commercial use.
Nanotechnology's bright future has finally come up with a possible treatment for the dreaded pimples of our teen years. That has arrived in the form of gold nano-bombs which deliver a lethal dose of lauric acid to skin-dwelling bacteria responsible for that unsightly acne, according to UPI.
A new nanoprobe can slip stealthily into a cell and give researchers an opening to monitor the cell's insides for up to a week. That could make the tiny inorganic device the first to implant within a cell without damaging it.
Adorable buckyballs can act as soccer-ball-shaped molecular cages to deliver designer drugs or even radioactive particles to attack diseases such as cancer. Now scientists have found that a certain buckyball configuration can put human skin cells into a sort of suspended animation where they don't die, divide, or grow -- a toxic condition for the human body that might also lead to possible treatments.
Scientists have created the world's smallest superconductor, from a sheet of four molecule-pairs less than a nanometer wide. That's far smaller than the head of a pin -- which stretches across a million nanometers -- and more on the order of a DNA molecule, which is about 2 nanometers wide.
Superconductivity has been considered a large-scale phenomenon ever since its discovery in 1911. But the new study by Ohio University scientists suggests that nanoscale superconducting wires could become a very real possibility for powering tiny electronic devices or other energy applications.
While so many scientists spend their time trying to create nanobots the size of bacteria, researcher at the NanoRobotics Laboratory of the École Polytechnique de Montréal, Canada, decided to simply take direct control of live bacteria.
The ability of matter to move light underpins such common phenomena as transparency, refraction, and reflection. But light moving matter? That's a bit rarer. So rare, in fact, that University of Michigan researchers refused to believe the results of their experiments for almost four years. As reported in the latest Science, they had discovered special nanoribbons so sensitive that light actually caused them to move.
