Area of Science:

Analytical Chemistry
Mobile Health Technology

Background:

Scanometric assays are a method for quantitative chemical analysis.
Traditional detection platforms often require specialized equipment, limiting accessibility.

Purpose of the Study:

To demonstrate the feasibility of using smartphones as a platform for quantitative scanometric assays.
To develop and validate a mobile application for analyzing scanometric assay data.

Main Methods:

Comparison of different scanning modes (color, grayscale, black/white) and grayscale conversion protocols.
Development of a mobile application for imaging and analyzing scanometric assays.
Validation using paper-printed tests and a biotin-streptavidin assay.

Main Results:

The mobile app demonstrated comparable performance to traditional desktop scanners for optical darkness ratio (ODR) analysis.
Different scanning modes and protocols were evaluated for ODR determination.
Successful application on both paper and plastic substrates.

Conclusions:

Smartphones are a practical and accurate platform for quantitative chemical analysis.
Mobile devices can enhance accessibility for medical diagnostics and chemical testing.
The developed app provides a user-friendly solution for scanometric assay analysis.
