I honestly confess I had no clue what is Plasmon Resonance until I read this article and seems like ATS neither, when I typed that name on the search engine.




Utilizing optical characteristics first demonstrated by the ancient Romans, researchers at the University of Illinois at Urbana-Champaign have created a novel, ultra-sensitive tool for chemical, DNA, and protein analysis.


A great tool for scientist I must say. So glad to see another invention based on an ancient culture knowledge.


The Lycurgus cup was created by the Romans in 400 A.D. Made of a dichroic glass, the famous cup exhibits different colors depending on whether or not light is passing through it; red when lit from behind and green when lit from in front. It is also the origin of inspiration for all contemporary nanoplasmonics research—the study of optical phenomena in the nanoscale vicinity of metal surfaces.

Very interesting I did not know about this cup. It's amazing the things our forefathers were capable of creating, without having any clue at all how it worked. Stained glass windows are an example of nanotechnology at work.

Try just plasmon, or plasmonic, and you'll find me posting stuff for years.

It's a big new field.

I was just reading about this cup earlier and decided to do a quick search here for it


It really is amazing, and a stunning example!



The ancient nanotech works something like this: When hit with light, electrons belonging to the metal flecks vibrate in ways that alter the color depending on the observer’s position. Gang Logan Liu, an engineer at the University of Illinois at Urbana-Champaign, who has long focused on using nanotechnology to diagnose disease, and his colleagues realized that this effect offered untapped potential. “The Romans knew how to make and use nanoparticles for beautiful art,” Liu says. “We wanted to see if this could have scientific applications.”


pretty cool


here is a link for more info.

Pretty cool for sure.

Although I don't understand why it was a roman cup that inspired him. Dichroic glass (sometimes simply called "dichro" in the lampworking world) has been used in glassware up until today. Hippies have been making "tobacco pipes" with dichro for years.

My point is, you think someone working with optics would be familiar with a common type of glass and not have to be inspired from a roman cup.

It's like saying I built my house from concrete because I was inspired by a concrete roman structure. It would be more accurate to say I built my house of concrete because it's known material that worked well for what I wanted.
