Chain mail nano-coat made from synthetic DNA

DNA bundles transform into stable chain-armor-like nanostructures by copper-catalyzed azide?alkyne click chemistry.

Measuring the mass of molecules on the nanoscale

By observing the shift in eigenstates of coupled microcantilevers, researchers can measure nanogram-scale mass in a liquid environment with extreme accuracy.

Researchers simulate behavior of 'active matter'

Researchers have shed new light on a particular class of active matter called active colloids - collections of tiny moving particles suspended in fluid. Using numerical models and computer simulations, the researchers show how spinning particles, pushed about by the fluid flows created as each particle spins, can arrange themselves into an array of emergent macro-scale patterns.

Nanotechnology legal and regulatory frameworks in South-East Asia

Researchers in Malaysia are asking whether existing legal and regulatory frameworks in South-East Asia are robust enough to consider the safety issues surrounding nanotechnology.
