For half a millennium, people have tried to enhance human vision by technical means. While the human eye is capable of recognizing features over a wide range of size, it reaches its limits when ...

Scientists are reducing the size and costs of medical microscopes to make it possible to use them more widely, and hook them up to experts able to diagnose an illness even from far away. Falling ill ...

An EU-funded project is developing a super-resolution microscope small enough to fit on to a computer chip that can be used to see changes in living cells in real time. Potential applications include ...

Label-free, non-invasive, and quantitative monitoring of cellular activities is crucial for understanding various biological processes and the response of cells to therapeutic drugs. However, existing ...

For centuries diffraction limited the resolution of optical microscopy. The past 50 years have, however, seen one limitation after another buckle under the ingenuity of a host of wide-ranging ...

(Nanowerk News) Falling ill in a remote part of the world can mean difficulty in finding the right care. Even where medical help may be available, it may be impossible to get a definitive diagnosis ...

(Nanowerk News) The resolution achievable with conventional optical microscopes is limited because of the physical laws governing the wavelength of light. This means they cannot be used to directly ...
