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…

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…
