Inexpensive and disposable SPR substrates are produced by metal coating of commercial Blu-ray discs. A compact imaging apparatus is fabricated using a 3D printer which allows taking SPR measurements from more than 20.000 individual pixels. Real-time bulk refractive index change measurements yield noise equivalent refractive index changes as low as 4.12 × 10−5 RIU which is comparable with the detection performance of commercial instruments. As a demonstration of a biological assay, we have shown capture of mouse IgG antibodies by immobilized layer of rabbit anti-mouse (RAM) IgG antibody with nanomolar level limit of detection. Our approach in miniaturization of SPR biosensing in a cost-effective manner could enable realization of portable SPR measurement systems and kits for point-of-care applications.EnglishOptical sensorPlasmonicsSurface plasmon resonance imaging3D printersAntibodiesBiosensorsChemical detectionCost effectivenessMammalsPlasmonsRefractive indexResonanceSemiconductor quantum wellsSignal encodingSmartphonesCommercial instrumentsDetection performanceEquivalent refractive indexMobile sensingOptical discsRefractive index changesSurface plasmon resonanceArticle10.1016/j.snb.2016.08.061
