A Study on the Relation Between Voltage and Bilirubin Concentration in Artificial Blood Solution by Bilirubin Detector

Abstract

This research project focuses on investigating the correlation between electric potential difference and bilirubin concentration within an artificial blood solution, utilizing the principles of light absorption. The bilirubin detector's design and construction incorporate a blue light source with a 460 nm wavelength and a green light source with a 560 nm wavelength, enabling interaction with bilirubin concentrations ranging from 2 to 14 mg/dl. Analysis of the project's outcomes revealed a direct relationship between the bilirubin detector's output voltage and the concentration of the bilirubin solution. Notably, an interaction with bilirubin was observed at the 460 nm wavelength, influencing light absorption. In cases of higher bilirubin concentration, light transmittance was diminished, leading to a heightened voltage difference. Conversely, lower bilirubin concentrations facilitated increased light transmission, resulting in a reduced voltage difference. This study contributes to a comprehensive understanding of bilirubin detection methodologies and their potential applications in medical diagnostics.
