Glucan particles (GPs) could be considered innovative
and biocompatible microcarriers. Their high affinity for
Dectin-1 receptor, expressed on different phenotypes of
immune system cells, makes them suitable for imaging
inflammatory processes. In this work, GPs were
efficiently loaded with either paramagnetic Gd-based
compounds (for proton MRI) or perfluorocarbons (PFCs,
for
19
F
MRI). The carriers obtained showed very high values of
relaxivity and fair fluorine payloads. The limit of
sensitivity related to loaded GPs was explored both by
1
H
and
19
F
MRI. Moreover, J774.A1 macrophage incubation with loaded
GPs and subsequent MRI of cells at 7 T were performed.
