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.
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.

As first in the world, MP-SPR is able to separate transcellular and paracellular drug uptake [4] in real-time and label-free for targeted drug delivery. In biosensor development, MP-SPR is used for assay development for point-of-care applications. [3] [6] [7] [8] Typical developed biosensors include electrochemical printed biosensors, ELISA and ...
