Well, the device just got even more powerful. The group announced Tuesday that the CellScope is now capable of taking color images of malaria parasites and even of tuberculosis bacteria labeled with fluorescent markers.
The version of the Cellscope introduced in April works with handhelds and even Netbooks and can be used for bright field microscopy, which uses simple white light--such as from a bulb or sunlight--to illuminate samples. The new version adds fluorescent microscopy to the repertoire. The device can now take pictures of a target--such as a parasite, bacteria, or cell--tagged with a specific fluorescent wavelength emitted by a special dye.
