The water proton spin relaxivity, colloidal stability, and biocompatibility of nanoparticle-based magnetic resonance imaging (MRI) contrast agents depend on the surface-coating ligands. Here, poly(acrylic acid-co-maleic acid) (PAAMA) (Mw = ~3000 amu) is explored as a surface-coating ligand of ultrasmall gadolinium

The ability of self-assembling multivalent DNA-binding dendrons to interact with biological targets is modified by co-assembly with two novel low-molecular-weight cholesterol-functionalised PEG units, one based on triethylene glycol (Chol-PEG-3) and one on an octaethylene glycol (Chol-PEG-8). The addition of either
