Promega commercial fluorometer quantus tm

Schematic of the complete device used in this study is presented. The device comprises a <t>fluorometer</t> with an integrated graphene oxide (GO)–aptamer biosensor and a custom smartphone application. ( a ) The fluorometer is combined with the smartphone application. ( b ) An illustration of the GO–aptamer assay principle demonstrates that the fluorescence signal is absent when fluorescence-labeled aptamers bind to GO, resulting in fluorescence quenching. In the presence of the target molecules, the aptamers bind to them, dissociating from GO and leading to the recovery of the fluorescence signal.

Calibration curves for HSA detection using an aptasensor with two different fluorometers: ( a ) the Quantus TM commercial fluorometer and ( b ) the developed fluorometer. The curves plot fluorescence response against HSA concentration. Both devices exhibited sigmoidal correlation within the 0–1.6 mg/mL range. The Quantus TM commercial fluorometer results show two linear correlations, one between 0 and 200 μg/mL (upper graph ( a )) with Y = 0.0006593(X) + 0.01042 (R 2 = 0.98485) and another between 200 and 1600 μg/mL (lower graph ( a )) with Y = 0.02442(X) − 6.34609 (R 2 = 0.99374). The developed fluorometer results also display two linear correlations, one within 0–200 μg/mL (upper graph ( b )) with Y = 0.0017(X) + 0.0213 (R 2 = 0.93056) and another between 200 and 1600 μg/mL (lower graph ( b )) with Y = 0.5557(X) − 12.98087 (R 2 = 0.9961).

Correlation between the fluorescence intensities measured by the developed fluorometer and the commercial fluorometer in the analysis of albumin concentration in 130 urine samples (black dots). The linear equation for the correlation is y = 0.92628x − 16.134, and the coefficient of determination (R 2 ) is 0.9652, indicating a strong positive relationship between the measurements.
