Reversed-phase switchable-hydrophilicity solvent liquid-liquid microextraction of copper prior to its determination by smartphone digital image colorimetry

Deep eutectic solvent-based dispersive liquid–liquid microextraction followed by smartphone digital image colorimetry for the determination of carbofuran in water samples

“…26,28 DIC is an image analysis-based technique and an alternative for quantitative and qualitative analysis of various samples. [29][30][31] The RGB color model can process images acquired using accessible smartphones. DIC based on a smartphone had the advantages of convenience, stability, and exibility.…”

Smartphone digital image colorimetry for quantification of serum proteins

“…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.…”
