China and the UK research scientists 12, in the new issue of the journal science progress report, said they use common titanium dioxide nanoparticles preparation of super lens, a solid hemisphere can improve the resolution of the optical microscope 4 to 5 times, break through the limit of conventional optical microscope resolution significantly.

　　Zeng-bo wang in the study by the university of bangor, electronic engineering and materials department of fudan university in China Wu Limin collaboration.

　　Zeng-bo wang told xinhua reporter, said that they first put the titanium dioxide nanoparticles in a fluid medium, and then squeeze out with a syringe, drip to observation samples directly, forming half spherical objects, fluid evaporates to form a solid hemisphere super lens, diameter size of dozens of micrometers, thinner than a human hair.

　　Zeng-bo wang said that in ordinary white light illumination conditions, the traditional optical microscope can‘t see objects smaller than 200 nm, which is composed of high refractive index nanoparticles super lens, can improve the resolution of the optical microscope to record 45 nm.

　　In simple terms, the use of the super lens can make an ordinary optical microscope become a nanoscale optical microscope. Slot on the blu-ray disc, for instance, the finest only 100 nanometers, using ordinary microscope is invisible, but take advantage of this super lens can be observed directly. The results of the researchers hope that in the future can be applied to biomedical, truthfully observed when the viruses and cellular structure.

　　According to introducing, this technology USES of titanium dioxide nanoparticles are widely used in sunscreen cosmetics and white paint, is a kind of common material, the cost is low, and the preparation process is relatively simple. Zeng-bo wang said that if there are appropriate financial support, the technology is expected in a few years can be commercialized.
