Figure 1. CoFe2O4 NPs covalently functionalized with glucose and 2-NBDG.
(a) ATR-FTIR absorbance spectra: citrate coated MNPs (blue), 2-NBDG coated MNPs (black), D-glucose coated MNPs. The covalent reaction between MNPs and the glucose molecules can be appreciated by the peak at 1737 cm−1, associated with the ester bonding formation. (b) A representative SEM image of CoFe2O4 NPs; scale bar 80 nm. (c) MNPs size distribution (counts normalized to the total number of measured particles). MNPs mean size : 27 ± 3 nm.
