Shimmer microscopy – useful?
Microscopy has its origins from small lenses being put together for astronomy and then used for magnifying the small particles in a lake. Microscopy enabled the discovery of much what we know about cells, organelles and the function. It has also helped in the diagnosis of diseases – one of the earliest one being the…

Lens free microscopy
Lens free microscopy Microscopy whether electron microscopy or with visible light requires lenses. For electron microscopy, lenses incur significant design challenges and add aberrations. A startup in UK uses technology invented by Professor John Rodenberg to remove lenses altogether and compute the image from the diffraction pattern of the sample. This is similar to a…

Micro-Microscope
Cell phone camera’s are small. However, typically microscopes are large bulky devices that have large lenses to collect light and are used for getting high resolution magnified images that are coupled to bulkier high sensitivity camera’s. But what about in-vivo microscopy where the animal needs to be brought below the microscope to focus. The laboratories…

Nanotube label free imaging
A researcher, Ji-Xin Cheng, at Purdue university has figured out a label free method to label carbon nanotubes. Nanotubes are typically hard to see and with Cheng’s technique not only can you see the nanotubes but you can also visualize them within cells. The method is known as transient absorbtion and uses a pulsed near…
