Surface plasmon resonance (SPR) Surface plasmon resonance (SPR) is a phenomenon that occurs where electrons in a thin metal sheet become excited by light that is directed to the sheet with a particular angle of incidence, and then travel parallel to the sheet. Assuming a constant light source wavelength and that the metal sheet is thin, the ...
The concept of classical SPR has been since 1968 but the SPR imaging technique was introduced in 1988 by Rothenhäusler and Knoll. [16] Capturing a high resolution image of low contrast samples for optical measuring techniques is a near impossible task until the introduction of SPRM technique that came into existence in the year 1988.
Self-pierce riveting (SPR) is a process of joining two or more materials using an engineered rivet. [13] Unlike solid, blind and semi-tubular rivets, self-pierce rivets do not require a drilled or punched hole. [14] SPRs are cold-forged to a semi-tubular shape and contain a partial hole to the opposite end of the head.
Multi-parametric surface plasmon resonance (MP-SPR) is based on surface plasmon resonance (SPR), an established real-time label-free method for biomolecular interaction analysis, but it uses a different optical setup, a goniometric SPR configuration.

Hodgson was sent by the SPR in 1884 to India to investigate Helena Blavatsky and concluded that her claims of psychic power were fraudulent. [6] Among the phenomena that Hodgson investigated was the supposed miraculous Theosophical letters from the Mahatmas which were said to magically appear over a four-year period in a cabinet in the Shrine ...
