<p dir="ltr">A cost-effective, portable multichannel smartphone-based sensor (MSBS) was developed for quantitative determination of organic compounds in aqueous solution, supporting both absorbance and fluorescence measurements.
Description
The platform integrates a DVD diffraction grating, a smartphone CMOS camera, and six laser diodes and white LEDs as excitation sources within a compact 3D-printed housing, with a pixel-to-wavelength calibration yielding 0.168 nm/pixel resolution across the visible spectrum.
As a proof-of-concept, the MSBS quantified methyl orange, rhodamine B, and methyl violet in absorbance mode, and coumarin in fluorescence mode, achieving LODs of 0.64–2.72 µM and R² values above 0.994. Compared with a commercial Avantes spectrometer, the sensor showed good agreement in calibration sensitivity, supporting its potential for field-deployable environmental monitoring and food safety screening.</p>
