Cameraphone microscope extension revisited

Cameraphone microscope extension revisited

Back in March of 2008 we mentioned a class project from a group of UC Berkeley students working to develop a microscope extension for cameraphones. Led by Daniel Fletcher, the team has since updated their prototype, which is capable of acquiring objects at 1.2 micrometers across.

Metallurgical eye candy

An alloy of 1.3% copper, 0.3% magnesium, and 0.3% manganese in aluminum, etched with potassium permanganate and lye. So I woke up this morning all pumped up to blog about metallography. If you don’t already know, metallography is a type of scientific microimaging that involves mirror-polishing metal surfaces and then etching them with various reagents […]

Lensless micro-microscope on a chip

Fig. 1 (a) Architecture of the optofluidic microscope (OFM); set of three arrows: illumination; single arrow: flow direction. (b) Photograph of the OFM prototype compared with a U.S. quarter. The actual nanoaperture array is 600 µm long. (c) The top view of the OFM; denotes the isolated aperture; denotes the corresponding aperture, as explained in […]

Phytochemical microscopy

If you decide to hang out indoors this week, take a look at this Florida State University gallery of phytochemical micrographs– micrographs are photographs taken through microscopes; phytochemicals are chemicals produced by plants. Capsaicin – This chili pepper-derived spice packs the wallop in your hot tamale, but it is also a digestive aid, a topical […]
