Novel chiral dendrimer-triamine-coordinated Gd complexes with polyaminoalcohol end groups were synthesized and shown to have longitudinal relaxivity (r1) values 5 times higher than that of clinically used Gd-DTPA. The affinities of Gd-4a and Gd-4b for bovine serum albumin (BSA), respectively, were estimated by a quartz crystal microbalance (QCM) measurement. The amino groups of the dendrimer were...
Superparamganetic iron oxide-based contrast agents in magnetic resonance imaging (MRI) have offered new possibility for early detection of lymph nodes and their metastases. According to important role of nanoparticle size in biodistribution, magnetite nanoparticles coated with different polyethylene glycol (PEG) concentrations up to 10/1 PEG/iron oxide weight ratio in an ex situ manner. To predict...
