Summary

Researchers have developed a low-cost, smartphone-based fluorescence detection platform designed for identifying microorganisms and molecules in diluted samples. This system utilizes a standard smartphone camera as the optical detector, integrating it with a custom setup compatible with conventional 96-well plates. Unlike traditional microplate readers, such as the Perkin Elmer Victor Machine, this device omits expensive components like exciter filters, barrier filters, and photomultipliers. The core methodology involves correlating the RGB color values of the sample's image, captured by the smartphone, with the molar concentration of the fluorescent specimen present in the sample. This work is a preprint related to an upcoming IEEE publication.

Key takeaway

For research scientists or labs seeking to implement fluorescence detection with budget constraints, this smartphone-based platform offers a viable, low-cost alternative to conventional microplate readers. You can leverage existing smartphone technology to perform quantitative analysis by correlating image RGB values with sample concentrations, significantly reducing equipment expenditure without sacrificing essential detection capabilities.
