Lateral Flow Immunoassays - from Paper Strip to Smartphone Technology

Lateral flow immunoassays provide low cost, fast, portable and simple to use devices, with yes/no answers seen by the naked eye, that has found applications in agriculture, biomedicine, the environment, and food industries. Making these quantitative, via electrochemical or optical approaches, is the present day challenge, with a vision that one day, these will be connected to smartphone technologies, which exhibit a promising digital platform for point-of-care diagnostics, mobile healthcare and bioanalytical needs. These devices are fully automated and equipped with a high resolution camera, a powerful processor with high storage capacity, wireless connectivity, real-time geo-tagging, secure data management, and cloud computing.
