PocketELISA: A low-cost portable ELISA reader based on image analysis over PDA platform for clinical diagnose in medical veterinary

摘要

ELISA (Enzyme Linked Inmuno-Specific Assay) diagnostic plates are widely used for the screening of viral infections. Currently, plates are measured either photometrically, witch is costly, or manually, unacceptably subjective and dependent on training and illumination. In this paper, we propose an instrument for ubicuously reading out plates by digital analisys of images. The main challenge is designing a versatile platform using standard, low-cost elements, such as PDAs or embedded PCs, open libraries, and consumer-grade digital cameras. All these alternative solutions can provide similar results with small
