Smartphone camera or microscopic World 1st smallest camera(100 nm size) check LIVE Viruses activity!!!

(Check you body cells (just fon)) LIVE Viruses activity.

Smartphone cameras have improved a lot in recent years. They even have passable macro modes for focusing on tiny thing. If you want to focus on really small stuff, you’re going to need some additional hardware.
Aydogan Ozcan, a professor of electrical engineering and bioengineering at UCLA has created a smartphone attachment weighing less than half a pound that can detect objects far smaller than the human eye can, including viruses and synthetic nanoparticles.
It is extremely difficult to get clear images of the smallest of the small because the wavelength of light is too long. Doing that with an inexpensive mobile device is even harder. Equipment like the scanning electron microscope is massive and extremely expensive. The device developed by Ozcan is a fluorescent microscope, the body of which was 3D printed. The contraption uses a laser diode, which is directed at samples at a steep angle of roughly 75 degrees. This prevents the scattered light from interfering with the visual data.

The prototype device basically straps on to the back of a phone and lines up with the camera module. This isn’t just a device you can whip out of your pocket and snap a picture of viruses, though. You have to load the sample on a special tray and keep the device stationary to acquire a good image. When done correctly, the mobile sensor can produce images very similar to a scanning electron microscope.



Ozcan’s team used the mobile fluorescent microscope to capture images of the human cytomegalovirus (CMV), which is about 150-300nm in size. CMV is one of the larger viruses, but still tiny. Researchers were also able to detect 100nm nanoparticles marked with polystyrene beads.

Ozcan believes this approach could bring advanced imaging technology to more places, even those without reliable electricity No one can yet estimate how much a production version of the device would cost, but it would probably be far less than a scanning electron microscope and just a little more portable too.

Pressy Android App: Click button and make Call,Browsers,Social Network,Camera,etc.,

Pressy: the one-button Android controller so cool it was Kickstarted in under a day



If Kickstarter had a 24-hour funders club, Pebble and the Bolex Camera would be welcoming Pressy today. 

In under a day, the multifunction Android controller has more than doubled its $40,000 goal (raising $108,435 from 4,889 backers as of this writing) and with 45 days left to go, the numbers keep climbing. Perhaps its simplicity is what's making it such a hit. Pressy plugs into any Android device's headphone port (Gingerbread and above), and clicking its unobtrusive 0.7mm-tall button controls and automates any manner of your gizmo's functions. 

Through its app you can assign a given task to a sequence of clicks; it's up to you if it takes two short clicks to speed-dial your mom or one long press to snap an unobtrusive picture, for example. You can still use it if you have a pair of headphones in too, with the cans' play button subbing in for control. Clever.

Developer Nimrod Back has promised Pressy will be available within four months. A basic Pressy will set you back $17, for a choice of colors with a keychain storage sheath you'll have to pony up $25.
