Surface Plasmon Resonance Explained 

Huh?

Lepton Excuse me? Where do you live? I'll fight you right now--- it's 100% real science.

Lepton Anyone who think a science that specifically deals with macromolecules isn't real science should be put in jail or stoned at the city gates... I only noticed your comment because that Smock guy commented

Lepton which city do you currently reside in?

Lepton​ I've a guess that I'm talking to an American. You people give off a cyber scent

hey fellow once... How you doing?

It’s index of refraction change just above coverslip, so loss of signal due to increased scattering, since that also takes into account change in reflection angle. So yes, simple mass scatters light effect. I’m not sure how sensitive it is to change - one would think the layer thickness must need to change on the order of the size of the photons- so 200-400 nm, which would be tens of proteins deep, which is nonsensical. That’s the beauty of spr - the gold surface greatly reduces the size scale of photons to one or more layers of proteins, in effect! After that you just need a good detector for measuring small light changes in large signal which we have. I presume the light is exciting along the path of its resonance intensity minimum, and then see increase in emission intensity.

yes, the voice actually arouses me positively

SPR based devices detects local changes at or near the sensor surface by measuring changes in refractive index vs. time. These refractive index changes are plotted in SPR response plots, which are also called sensorgrams. The sensorgrams are used to derive important information about how an analyte interacts with the sensor surface, i.e. binding interaction selectivity and rates. In the case of using a bare gold sensor, if the analyte nears or binds to the gold surface, this would be observed in the sensorgram as an increase in SPR response. By studying the rate of SPR signal response change at different analyte concentrations, quantitative analyte interaction information can be extracted such to what extent an analyte is simply passing by, truly binding, non-specifically binding, or physically absorbing. hope this helps.

Thank you so much!! It really helped me. Then, even if the sensor is pure gold, the sensorgram takes the same form than a functionalized sensor (base line, association, dissociation, regeneration and baseline again) of course it depends for the concentration and the analyte itself. I'm asking because i used to think that a sensorgram produced with a chip non-functionalized looked diferent than a sensorgram with a functionalized sensor.
