Abstract

Developing portable, cost-effective analytical tools is crucial to expose students to advanced spectrometric systems in the undergraduate curriculum. Numerous Do-It-Yourself (DIY) systems and smartphone-based fluorescence spectrometers have been developed over the last few decades. These systems can be specific to one particular cell phone or require unique configurations that are relatively difficult to implement in classroom or laboratory settings due to a diverse pool of students’ owned cell phones. This work presents the design and validation of a cell-phone-based fluorescence spectrometer (FluoroBox). The system presented herein can be attached to any cell phone and adopted in classroom, online, hybrid, and laboratory settings, thus creating a versatile and universal system for adoption. The 3D-printed unit only requires a student’s smartphone camera, a blue laser, a cuvette, a diffraction grating, and batteries. FloroBox’s performance is validated through the qualitative analysis of edible oils. This study demonstrates the assembly, acquisition, and data processing compared with a conventional benchtop fluorescence spectrometer. By employing easily exchangeable units such as slits, excitation sources, and other elements, the device can detect fluorescence emissions from various fluorophores. This unit provides students with hands-on experience in fluorescence spectroscopy across multiple learning environments. The compact design, ease of use, and integration with mobile technology underline its potential for widespread adoption, particularly in resource-limited settings.

期刊介绍: The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
