Procedures for measuring spin-echo, and the free induction decay (FID) NMR signals.
A spin-echo NMR signal for Fe3O4-CRP with χ = 1.5 × 10−4 emu/g.
Temperature dependence of the spectral linewidth for Fe3O4-antiCRP with χ = 2 × 10−4 emu/g.
Temperature dependence of 1/T2 for Fe3O4-antiCRP with χ = 2.0 × 10−4 emu/g.
1/T1 and 1/T2 of as a function of χ for Fe3O4-antiCRP. Also shown are the 1/T1 and 1/T2 of ferrofluids in the same measuring fields.
