Abstract:
Hyperbranched polymers based on the poly(amidoamine), HyPAM, were used to synthesize gadolinium phosphate nanowires under mild conditions. Control of the average particle size was obtained by adjusting polymer concentration. Proton relaxivity measurements reveal an optimum particle size, reaching relaxivity values as high as 55 ± 9 mM(-1) s(-1) for r1 and 67 ± 11 mM(-1) s(-1) for r2. The colloidal stability of these hybrid systems were optimized through the use of functionalized core-shell polymers containing PEG segments and C18-PEG segments, structures which also offer the possibility of imparting additional function into the polymer-particle hybrids.
