Surface plasmon resonance (SPR) is a developing field verdict a wide-ranging variation of applications particularly in optical communication systems.
We found that the obtained LOD using the LR-SPR is lower than that with conventional short-range SPR (i.e., 3.3 x [10.sup.8] cells/ml) [25, 26] and also lower than that with long-range surface plasmon waveguides that exhibited the LOD less than 3 x [10.sup.5] cell/ml [33].

More recently, there has been a shift towards working in the sub-micron to nano structure scale (sometimes referred to as sub-wavelength structures), where unique optical phenomenon occur such as surface plasmon resonance.
As the light strikes the sensing area, it excites free electrons, causing them to oscillate and generate a highly confined propagating surface wave, called a surface plasmon polariton.
Surface plasmons solve the wavelength problem, and active plasmonics solve the surface plasmon power problem, but now we've got to keep all these actively pumped components from overheating due to all the excess energy we're adding.
