Can someone please make a picture to go with the new example? I tried to make the example as simple as possible, but I think that it would easily benefit from a picture of a window and a picture of a window with a gold film behind it.

Not sure how to go about sorting it yet, but this description of SPR is really about the application of the phenomenum in biological analysis rather than SPR itself, which a property most often observed in gold nanoparticles.

A solution that immediately springs to ming is to have this page talk about the phenomenon of Surface Plasmon Resonance described here, and to create a new page for Surface Plasmon Resonance Biosensors for the utilisation of the phenomenon in optical biosensors.

Besides, Surface Plasmon Resonance is propagative while Surface Plasmon Polaritons on nanoparticules are localized.

Tried to create an SPR page that describes both planar SPR and localized SPR. Both are used for biosensing, but both can be used for other applications as well. User: Ucispr, 01 May 2006.

What do the units of RU stand for? These are sometimes given with data and relate to the amount of bound species. - JamMan 4th Nov 06

RU = Response Units. There is a formula to compute this quantity, but roughly 0.1° SPR angle change corresponds to 1000 RU. Axelve 23:20, 8 November 2006 (UTC)

Oh, and that relates to roughly 1 nanogram per square millimeter (ng/mm^2) bound protein. Axelve 23:26, 8 November 2006 (UTC)

I removed the Law Enforcement tag, after reading the article I don't see that it has anything to do with LE. If I am wrong, because the articel is over my head, please put the tag back EMT1871 10:08, 20 January 2007 (UTC)

[edit] Kretschmann

The pic with SPR setup uses a triangular prisma. Doesn't the Kretschmann setup us a semi-cylindrical prism? Benkeboy 13:21, 1 February 2007 (UTC)

I believe the Kretschmann configuration is defined by contact between the prism and the sample.

[edit] Example

The example needs to be rewritten and should not be the first section of this article. I may have some useful pictures but not enough time or motivation to add them right now. If you give me an e-mail address here or on my talk page, I can send you a great book on surface plasmons with many useful diagrams. JoeCarson 13:50, 4 April 2007 (UTC)

What's the problem with the example? Looks like it's quite clear to me. Cannot we add it? --Cyclopia 11:30, 5 April 2007 (UTC)

The quality of writing is poor and it's too long. It also seems too oversimplified to do SPR justice. A shorter example with a good diagram would be preferable.JoeCarson 13:29, 5 April 2007 (UTC)

I agree, but itt's anyway better than nothing. It surely helps newbies on the subject even in its present state. I personally would readd it to the article, with a "not of encyclopedic quality" warning tag (don't remember the correct tag now, sorry). --Cyclopia 22:06, 5 April 2007 (UTC)

An example would be great. However, we need a good diagram and decent writing to go along with it. I believe leaving the page as is would be better than inserting that example.JoeCarson 11:26, 8 April 2007 (UTC)
