Cover Story: Simple analytical devices suitable for the analysis of various biochemical and immunochemical markers are highly desirable and can provide laboratory diagnoses outside standard hospitals. This study focuses on constructing an easily reproducible do-it-yourself ELISA plate reader biosensor device, assembled from generally available and inexpensive parts such as 3D printed objects and a common smartphone camera. The final colorimetric biosensor was able to process standard 96-well microplates and was verified on the TNF-alpha assay. The results of this study will inform the development of simple analytical devices easily reproducible by 3D printing and found on generally available electronics. View this paper
