3D Printed Microscopes to Boost Science in Developing Countries
Dr Richard Bowman from the Department of Physics, working with collaborators at the University of Cambridge and Tanzanian “digital blacksmiths” STICLab, wants to create much cheaper, open-source devices such as microscopes which can be used for disease diagnosis and scientific research. The three-year project, funded through the Global Challenges Research Fund, is testing and refining a prototype general purpose optical microscope made from mass produced lenses, a Raspberry Pi mini-computer and a 3D-printed plastic frame...

A Pocket-Sized Retina Camera, No Dilating Required
It’s the part of the eye exam everyone hates: the pupil-dilating eye drops. The drops work by opening the pupil and preventing the iris from constricting in response to light and are often used for routine examination and photography of the back of the eye. The drops sting, can take up to 30 minutes to work, and cause blurry vision for several hours afterwards, often making them inconvenient for both patient and doctor. Now, researchers at the University of Illinois at Chicago College of Medicine and Massachusetts Eye and Ear/Harvard Medical School have developed a cheap, portable camera that can photograph the retina without the need for pupil-dilating eye drops...
