A cost-effective smartphone-based device for rapid C-reaction protein (CRP) detection using magnetoelastic immunosensor

A smartphone-based C -reaction protein magnetoelastic (CRP-ME) immunosensor was developed. In this study, CRP can be detected with a sensitivity of 12.90 Hz μg −1 mL −1 and detection limit of 2.349 × 10 −4 μg mL −1 .
