Abstract: ABSTRACT Light-less Central controlling unit-less detachable Colorimetric Module converting smart-phone back-light into colorimeter The present invention provides a method for converting a smartphone into a portable colorimeter for quantifying analyte concentration in a sample. The system utilizes the smartphone's backlight [101] as the light source, with a detachable colorimetric detector [103] equipped with a wavelength filter [102]. The detector's output signal is transferred to the smartphone via a USB cable [104], and the signal is processed through a mobile app interface [105] that correlates absorbance values to concentration values. The app stores calibration data and computes the analyte concentration. The smartphone's backlight brightness [101] can be adjusted for enhanced sensitivity, and the detector [103] includes a photodetector that outputs an electrical signal proportional to transmitted light intensity. The wavelength filter [102] ensures the light matches the analyte's absorption spectrum. The app [105] features algorithms to convert raw data into calibrated concentration values, utilizes cloud connectivity [106] for data sharing, and updates calibration curves [107]. The module is detachable [108], providing flexibility for use across different sample types.
