Rhodamine bound maghemite as long term dual imaging nanoprobe of adipose tissue derived mesenchymal stromal cells

The paper focuses on labeling efficiency, localization, and fluorescence properties of rhodamine derivatized superparamagnetic maghemite nanoparticles (SAMN-R) in mesenchymal stromal cells (MSC). The stability of SAMN-R in intracelullular space during long time culture (20 days) is investigated. Featured analyses were based on advanced confocal microscopy accompanied by atomic absorption spectroscopy (AAS) and magnetic resonance imaging.
