Scientists have developed a new material that retains water drops and prevents them from sliding off the surface.

Australian scientists have developed a new material that traps water drops and prevents them from sliding off the surface.
The new material, which is made using a material called "raspberry particles" due to its resemblance to raspberry in appearance, prevents the water drops on the surface from sliding off even when the surfaces are turned face down.
The new material, shaped with the help of nanotechnology, has many uses, from making some high-tech medical tests cheaper and easier with simpler instruments to reducing fogging from airplane cabins.

Pointing out that the strips of “raspberry particles” they developed act like an adhesive tape for water, the researchers pointed out that with the help of the new material, surfaces that stay dry forever, never require cleaning or keep bacteria, and do not allow mold and fungus formation can be designed. The researchers pointed out that if the structure was adjusted to allow water to spread more quickly, the same material could be used to design fast-drying walls and roofs that would help houses cool quickly.

The scientific study of the new material developed by University of Sydney researchers has been published in the scientific journal Chemistry of Materials.
From Sydney University School of Chemistry, who headed the writing team that wrote the research. Andrew Telford stated that the new material was made by imitating the structure of the petals of roses, which have the ability to hold water drops thanks to the special structure of their surfaces. Telford noted that the research team obtained the material in question by combining "raspberry particles" in the laboratory with the help of round-shaped micro and nano particles to form the structure of the rose petal.

Underlining the commercial potential of the material, Telford said that his scientific work was the first discovery that allowed the preparation of raspberry particles on an industrial scale. “We are now in a position to supply these particles in large quantities without the need for specialized manufacturing facilities and tools,” Telford said.
