Figure 3. (a) Structural
and performance illustration of MNP6,
ANP6, MANP6:6, and actual photographs of
MNP6, ANP6, MANP6:6with/without applying an external magnetic field under day light and UV
light. (b) Magnetic hysteresis loops of MNP6 and
MANP6:6 obtained on a SQUID system at 300 K. (c)
Fluorescence photos of ANP6 and MANP6:6and the corresponding color maps in different particle concentrations.
(d) Fluorescent intensities of different concentrations of
ANP6 and MANP6:6 sprayed on paper
strips. (e) Fluorescent intensity, magnetic recovery, and hydrodynamic
size of MANP6:6 dispersed in aqueous solutions with pH
values ranging from 2 to 11. (f) Fluorescent intensity, magnetic
recovery, and hydrodynamic size of MANP6:6 stored in
water at 60 °C for 7 days. Fluorescent intensity, magnetic recovery, and
hydrodynamic size of MANP6:6 incubated in (g) 10 mM PB
(pH 7.4), (h) human serum, and (i) human urine for 7 days.
