Single tip assays in calf serum using iPhone and CCD camera imaging: (A) reproducibility of colorimetric detection (n = 4) for VEGF; (B) change in colorimetric signal with increasing concentration of VEGF; (C) calibration curve obtained via iPhone imaging color intensity (K%) vs [VEGF]; (D) reproducibility of colorimetric detection (n = 3) for IGF-1; (E) change in colorimetric signal with increasing concentration of IGF-1; (F) calibration curve obtained via iPhone K% vs [IGF-1]; (G) raw CL images captured by CCD camera for PSA; (H) recolorized images showing change in CL intensity vs [PSA]; (I) calibration curve of relative CL vs [PSA].
