This is quite remarkable to use an usual camera, to diagnose a disease. Those who managed to achieve this are biomedical engineers from a U.S. university. And, it seems, this process can be replicated easily.
Medical team captured the image of the cells with a bundle of fiber optic attached to a Olympus E-330 camera. Then they applied a fluorescent dye that caused all the nuclei of cells simply glow when it was lit with fiber optic beam.
Pre-cancerous and cancerous cells are usually quite distorted and they can be seen even on a camera LCD screen.
Next step: implementing a software that could help doctors identify malignant cells, without involving pathologysts.
However, what makes this research truly remarkable is that it may be performed again at very low costs.
