Figure 1. Determination of the dissociation constant for various molecular interactions via magnetic relaxation and bMR nanosensors.
A) Avidin – Biotin, B) Protein G – IgG, C) Dextran –Concanavalin A, D) Folic acid – Folate receptor (FR) expressed on HeLa cells, E) anti-folate-receptor antibody – Folate receptor on HeLa cells), F) anti-EpCAM antibody – EpCAM Receptor (MCF-7 Cells). (Errors were within 1–2%, which are too small to depict).
