Scientists have developed a new material

Scientists have developed a new material that can be painted onto surfaces to keep them wet or dry, and which never needs cleaning.

The new nanostructure coating, reported in the journal Chemistry of Materials, could reduce condensation in aircraft cabins, keep walls and roofs dry in buildings, or be used for some medical tests in remote areas without the need for high tech laboratories.

"We call them raspberry particles because they're composed of spherical nanoparticles, held together in raspberry shaped structures," says study lead author Dr Andrew Telford of the University of Sydney.

"Raspberry particle films can be described as sticky tape for water droplets. They can trap tiny drops, preventing them from rolling off surfaces, even upside down."

Telford and colleagues based their idea on the structure of water repellent surface layers found on some rose petals, which cause water droplets to bead up into balls.

Thinkin of what i will also develop...e...hm! ...wait! Before i tell u mine, do you think of developing any? Wot's it?
