encapsulated iron oxide particles, all the polymeric material migrated so that it
ended up adhered to the vial wall close to the magnet (Fig. 9).
Analogous experiments, monitored by confocal microscopy, performed with
quantum dots (Lumidot CdSe/ZnS, 590 nm) and fluorescent dyes
(5,6-carboxyfluorescein and rhodamine B isothiocyanate) further confirmed the
efficiency of HPMC nanospheres as versatile encapsulating agents (Fig. 9).

MTPA (3) is another known CDA that was incorporated as pendant of PPAs.
Although the presence of a C 6 H 4 -NH-C(¼O)-C(ÀOMe) system (as in
MPA-PPAs) gave rise to expectations about a similar behaviour of these polymers
