Could FA-PG-SPIONs act as a hyperthermia sensitizing agent? An in vitro study

The therapeutic effect of polyglycerol coated iron oxide nanoparticles (PG-SPIONs, non-targeted nanoparticles) and folic acid-conjugated polyglycerol coated iron oxide nanoparticles (FA-PG-SPIONs, targeted nanoparticles) in combination with hyperthermia on viability of HeLa cells was investigated. It was observed that coated and uncoated SPIONs have spherical shapes with an average diameter of 17.9 ± 2.85 nm and 5.4 ± 0.75 nm, respectively. The...
