Two dimensional fluorescence difference spectroscopy (2D FDS) detects nanoparticle interactions following surface functionalization and biomolecule loading by generating a spectral signature of the fluorescent intensity per excitation and emission wavelengths. Comparing metal oxide nanoparticles revealed a unique spectral signature per material composition. 2D FDS showed to be sensitive to chan...

In regenerative medicine, noncontact manipulation of cells enables new possibilities for tissue engineering. Due to their physicochemical properties, superparamagnetic iron oxide nanoparticles (SPIONs) are used in biomedicine various applications, e.g., as drug transporters, contrast agents or make maneuverable by magnetic forces. SPIONs attached and/or taken up enable targeting adoptive immune...

In this study, cobalt aluminate was prepared by a sol-gel method. XRD and FTIR analyses of the precursors obtained at 300 °C for 12 h revealed that type complexing agent used in synthesis affects pyrolysis step. An amorphous phase using citric acid as agent. A beginning crystallization observed agents such polyacrylic glycine. The structural investigation starting reagents lines exhibit charact...
