“…Typically, SDIC is most comparable to UV/Vis spectrometry, and as such, it is one of the most used instruments for comparison study [42,43]. Other instruments that have been used include flame atomic absorption spectrometry [44], highperformance liquid chromatography [37], and fluorescence spectroscopy [45]. Because of the portability of SDIC, it has been applied for on-field analysis [28].…”

Analytical instruments used for scientific research and education are often expensive. This limitation poses a challenge for schools and educators in low-income countries to provide practical science training to students. To address this problem, the improvisation of analytical instruments and instructional materials has emerged as a viable solution. By incorporating practical experiments into science education, students have the opportunity to engage directly with scientific instruments, conduct investigations, and collect data. This hands-on approach fosters a deeper understanding of scientific principles, enhances critical thinking skills, and cultivates scientific mindsets among students. Herein, we review and discuss, step-by-step, the approach of using a smartphone for quantitative analysis, referred to as smartphone digital image colorimetry (SDIC). SDIC, with its practicality and accessibility, utilizes smartphone digital cameras for image acquisition and the freely available image processing programs, such as ImageJ and smartphone Apps, for image quantification. Using SDIC can enable students in low-income countries to develop essential scientific skills, including critical thinking, data interpretation, and an evidence-based approach to scientific research. By leveraging the ubiquity and affordability of smartphone technology, SDIC offers an accessible and cost-effective approach to practical science education, bridging the gap between theory and practice in resource-constrained settings.

“…27 Typically, one of the channels is more intense than the others; this channel is chosen for quantication by translating the pixel intensity of the image into a value that is correlated with the analyte concentration. 28 SDIC has opened colorimetric analysis to low-budget laboratories including a wider range of researchers and students 29 and has been applied in the analysis of a variety of samples such as food, 28,[30][31][32] environmental samples, 33 alloys, 34,35 drugs [36][37][38] and vitreous humor. 39 In this study, we expand the applicability of SDIC to the quantication of serum proteins.…”
