Figure 2

Photographs of (A) MNPs, (B) TMC–MNPs, (C) BN–TMC–MNPs, (D) DOTA–BN–TMC–MNPs, and (E) 68Ga–DOTA–BN–TMC–MNPs in suspension. TMC–MNPs, BN–TMC–MNPs, DOTA–BN–TMC–MNPs, and 68Ga–DOTA–BN–TMC–MNPs showed dispersion stability in suspension, but MNPs (A) precipitated quickly.

Abbreviations: MNP, magnetic nanoparticle; TMC, N,N,N-trimethyl chitosan; BN, bombesin; DOTA, S-2-(4-isothiocyanatobenzyl)-1,4,7,10-tetraazacyclododecane tetraacetic acid; 68Ga, gallium-68.
