“…To render the prepared heteronanocrystals to disperse in the aqueous biological environment, we modified the heteronanocrystal surface by using NOBF 4 and sodium citrate according to literature. , Then, we tested the stability of the Fe 3 O 4 –Ag 2 S heteronanocrystals with and without surface modification dispersed in water, fetal bovine serum (FBS), and PBS solutions. As shown in Figure a, the Fe 3 O 4 –Ag 2 S heteronanocrystals without surface modification precipitated in the tested 48 h in the water, FBS, and PBS solutions.…”

“…SPR of AFNSs is also red-shifted as a consequence of the refractive index increase on the gold surrounding media [ 69 , 73 , 76 , 89 ]. For instance, Umut et al [ 55 ] compared the absorption spectra of Au-Fe 3 O 4 dumbbell and core–shell NSs, constituted of an approximatively 8 nm sized Au core.…”

“…Yang's research group engaged the studies on the functionalized Au-Fe 3 O 4 nanocomposites for magnetic and colorimetric bimodal recognition of melamine [76]. They modified the Au-Fe 3 O 4 nanocomposites with l-(2-mercaptoethyl)-1,2,3,4,5,6-hexanhydro-s-triazine-2,4,6-trione (MTT) and used them in bimodal sensing of melamine.…”
