Microscopes

Bodelin's ProScope Micro Mobile is a microscope that mounts on the iPhone

Optics manufacturer Bodelin is no stranger to hand-held microscopes, having previously brought us a series that can be connected to the USB port of a laptop. Given that smartphones are in many ways replacing laptops, however, it shouldn’t come as a surprise that the Oregon-based company has now introduced its ProScope Micro Mobile – it’s a lab-quality microscope that mounts on the user’s iPhone.  Read More

A 3D image of a rotavirus, constructed from data gathered using the new technique

Traditionally, in order to view tiny biological structures such as viruses, they must first be removed from their natural habitats and frozen. While this certainly keeps them still for the microscope, it greatly limits what we can learn about them – it’s comparable to an ichthyologist only being able to study dead fish in a lab, instead of observing live ones in the ocean. Now, however, researchers at the Virginia Tech Carilion Research Institute have devised a technique for observing live viruses in a liquid environment. It could have huge implications for the development of treatments for viral infections.  Read More

Image of the shadow of a single ytterbium atom (Image: Griffith University)

A team of researchers at Griffith University has managed to stretch the capabilities of microscopy to its ultimate limit. Culminating a five-years effort, the scientists have obtained a digital image of the shadow cast by a single atom, in a development that might soon lead to important advances in scientific observations ranging from the very big to the very small.  Read More

A new X-ray microscope at Brookhaven National Laboratory is being used to create unparalleled high-resolution 3D images of the inner structure of materials. Using techniques similar to taking a very small-scale medical CAT (computer-assisted tomography) scan, the full field transmission x-ray microscope (TXM) enables scientists to directly observe structures spanning 25 nanometers - three thousand times smaller than a red blood cell - by splicing together thousands of images into a single 3D X-ray image with "greater speed and precision than ever before." This capability is expected to power rapid advances in many fields, including energy research, environmental sciences, biology, and national defense.  Read More

The practice of surgically removing diseased or damaged tissue within the body is something of a trade-off – quite often, some of the surrounding healthy tissue will also end up being removed in the process. In highly-sensitive areas such as the brain or spinal cord, where a fraction of a millimeter either way can have huge consequences, sometimes surgery is deemed to be just too risky. A newly-developed endoscopic laser “scalpel,” however, looks like it could lower those risks considerably.  Read More

Magnifi universal photoadapter case for iPhone 4 and iPhone 4S

The list of add-ons that let you to tinker with the photo taking capabilities of your iPhone is about to get even bigger with the launch of Magnifi. Rather than tacking a zoom or fish-eye lens onto the smartphone, Magnifi integrates an adapter into the case so that your phone can be hooked-up to most optical instruments with an eye-piece such as binoculars, microscopes or telescopes.  Read More

Researchers at the University of Sheffield have created what sounds impossible - even nonsensical: an experimental electron microscope without lenses that not only works, but is orders of magnitude more powerful than current models. By means of a new form of mathematical analysis, scientists can take the meaningless patterns of dots and circles created by the lens-less microscope and create images that are of high resolution and contrast and, potentially, up to 100 times greater magnification.  Read More

Scientists have created a scanner that can be attached to a mobile phone, to detect the pr...

Soon, you may never have to play Russian roulette with potato salad again. Instead of just hoping that E. coli bacteria aren't present in your foods or drinks, you could instead use your mobile phone to find out for sure. That phone would have to be equipped with a bacteria-detecting scanner, which researchers from the UCLA Henry Samueli School of Engineering and Applied Science recently created - in a prototype version, for now.  Read More

With a superlens microscope, everyday people would be able to see minute details of tiny o...

Some day, you may have a microscope on your smartphone camera that's as powerful as a scanning electron microscope. If you do, it will likely be thanks to research presently being conducted by Durdu Guney, an assistant professor of electrical and computer engineering at Michigan Technological University. He is working on creating a metamaterial-based "superlens" - a long sought-after optically-perfect lens, that could use visible light to image objects as small as 100 nanometers across.  Read More

A team from the University of California at Davis has developed an affordable way to give the iPhone surprisingly capable chemical detection and imaging powers. We've reported on cellphone microscopes before, but this version claims to be simpler in concept and less expensive, plus it adds spectroscopy to its list of abilities  Read More
