A little less force: Making Atomic Force Microscopy work for cells

Researchers have developed nano-sized cantilevers whose gentle touch could help discern the workings of living cells and other soft materials in their natural, liquid environment. Used in combination with a revolutionary detection mechanism, this new imaging tool is sensitive enough to investigate soft materials without the limitations present in other cantilevers. By placing a nanowire cantilever in the focus of a laser beam and detecting the resulting light pattern, scientists at the Molecular Foundry believe atomic force microscopy can be used to non-destructively image the surface of a biological cell.

Molecular 'machine' is a tail-biter which functions as a nanoswitch

The ouroboros (ancient Greek for 'tail devourer') is a motif found in many cultures: a snake biting its own tail, it symbolizes eternity and cycles. Researchers have now constructed a molecular tail devourer, and have named this new class of compound 'ouroborand'. Their tail-biter is a molecular 'machine', which functions as a nanocontainer with a built-in switch that regulates access to the cavity.

Magnetic fields drive drug-loaded nanoparticles to reduce blood vessel blockages

Scientists and engineers have used uniform magnetic fields to drive iron-bearing nanoparticles to metal stents in injured blood vessels, where the particles deliver a drug payload that successfully prevents blockages in those vessels. In this animal study, the novel technique achieved better results at a lower dose than conventional non-magnetic stent therapy.
