(Nanowerk News) Light microscopes based on scattering, reflection and absorption, or a combination of these, have been a key enabling technology for the study of objects invisible to our eyes, especially in the field of biology. Many improvements have been made in the past to create state-of-the-art techniques capable of achieving unprecedented resolution and sensitivity albeit their cost, which drastically increases with quality and versatility, making them quite unavailable for general applications.

. . .
The researchers have developed a large FOV interferometric on-chip lens free microscope (LIM) based on a novel design with a very high axial sensitivity and DOF, applying a technique adequate to be used in microarray platforms for the detection of proteins without the need of labels.
.
. . .
By using collimated polarized light, the team of scientists was able to reconstruct the image by shining light through the transparent sample to observe and analyze the phase shift and interference intensity pattern, a technique known as phase-shifting interferometry (PSI). As UPC Prof at ICFO Juan P. Torres states, "any slight refractive index change introduced by an impurity in the sample is translated into a phase difference and thus an intensity variation in the pattern, showing the contours and therefore size of the irregularity".

I'm clearly an ignorant layman in such matters.
.
However, that sounds a bit exciting, to me.
.
I'd think it would have applications in hospitals and even the average MD's office.
.
And what fun in schools!
.
Anyone think you could build one with such information?

Your link doesn't work mate.

But Macgyvering anything and handing it to the masses, that usually is the exclusive domain of the rich and positioned, is alright by me.

Sorry. I searched on the sight and came up with a literal blank. May try dogpile.com later.

Thanks.

Wellllll, 5 pages of a dogpile.com search turned up no such article.

TRYING AGAIN.

This link still worked from the alternative news referral link:

Let me try and paste it in with spaces between

www space dot space nanowerk space dot space com

to turn it off and then folks can paste it into the URL window without the spaces and see if that works:

www . nanowerk . com/nanotechnology-news/newsid=43670.php?utm_source=feedblitz&utm_medium=FeedBlitzRss&utm_campaign=nanowerkemergingtechnologiesnews


OK, THAT DID WORK. I pasted the last link just above in the URL slot . . . then removed the spaces as I mentioned and it worked.

Crazy.

Finding imperfections in gemstones would be one use.
Also, realtime water purity/clarity.
