Figure 2From: Transferrin-targeted magnetic/fluorescence micelles as a specific bi-functional nanoprobe for imaging liver tumorMagnetic and fluorescent properties of SPPTC. The r2 of SPPTC is 196.5 mM−1 s−1 and the r2 of SPPC is 219.1 mM−1 s−1 at 300 K respectively (a); the correlation between fluorescence intensity and the concentration of the nanoprobe (b).Back to article page
