Partially phosphonated polyethylenimines are promising polymers for nanoparticle (NP)  surface modification. A number of phosphonate and amino groups are easily controlled and permit to access to the functionalized NPs with a large range of zeta potential and diameter. The strong anchoring on metal oxide NPs is assumed by phosphonates. Numerous amine functions preserve dispersion and are the key to a subsequent biofunctionalization.
