Query: Versatile coating platform for metal oxide nanoparticles: applications
  to materials and biological science   In this feature article, we provide an overview of our research on
statistical copolymers as a coating material for metal oxide nanoparticles and
surfaces. These copolymers contain functional groups enabling non-covalent
binding to oxide surfaces and poly(ethylene glycol) (PEG) polymers for
colloidal stability and stealthiness. The functional groups are organic
derivatives of phosphorous acid compounds R-H$_2$PO$_3$, also known as
phosphonic acids that have been screened for their strong affinity to metals
and their ability to build multidentate binding. Herein we develop a
polymer-based coating platform that shares features with the techniques of
self-assembled monolayers (SAM) and Layer-by-Layer (L-b-L) deposition. The
milestones of this endeavor are the synthesis of PEG-based copolymers
containing multiple phosphonic acid groups, the implementation of simple
protocols combining versatility with high particle production yields and the
experimental demonstration of the colloidal stability of the coated particles.
As a demonstration, coating studies are conducted on cerium (CeO$_2$), iron
($\gamma$-Fe$_2$O$_3$), aluminum (Al$_2$O$_3$) and titanium (TiO$_2$) oxides of
different sizes and morphologies. We finally discuss applications in the domain
of nanomaterials and nanomedicine. We evaluate the beneficial effects of
coating on redispersible nanopowders, contrast agents for In Vitro/Vivo assays
and stimuli-responsive particles.
