The concentration of hGH in the urine can be calculated from the concentration of hGH in NIPAm/CB nanoparticle eluate by means of a calibration curve. Solutions obtained by dissolving rhGH in synthetic urine at decreasing concentration from 830 to 0.83 pg/mL were incubated with NIPAm/CB nanoparticles. Standard deviation of the concentration of hGH in NIPAm/CB nanoparticle eluate is always below 10% of the average value (3 replicates). Linearity between the concentrations in urine and particle eluate is evident, and the relationship can be mathematically described by y= 19.41x+ 0.28 (r= 0.999). In the blue square a magnification of the curve for the low concentration range (83 pg/mL - 0.8 pg/mL). For hGH concentration in the original urine solution of 0.8 pg/mL a concentration of 0.3 ng/mL was measured by Immulite in the NIPAm/CB nanoparticle eluate.
