Researchers at the Pohang University of Science and Technology in Korea have developed nanolenses capable of imaging objects too small for conventional lenses. They can also be used for ultraviolet lithography and detecting infrared light emitted by quantum dots. The ...

Scientists at the University of California, Davis, have recently designed a contact lens prototype with a built-in pressure sensor using a novel process that etches tiny electrical circuits within a soft polymer material. The new development could help glaucoma patients ...
