Synthesis of radioluminescent iron oxide nanoparticles functionalized by anthracene for biomedical applications

Superparamagnetic α-Fe2O3/Fe3O4 Heterogeneous Nanoparticles with Enhanced Biocompatibility

“…Although MFe 2 O 4 nanoparticles have exhibited excellent characteristics in the biomedical field, their safe application in the human body is a major problem owing to the heavy metal elements presented in MFe 2 O 4 [ 1 ], which also limits their applications in the biomedical field. So, as one of the typical nanomaterials, spinel iron oxide nanoparticles without heavy metal elements have been widely applied in many aspects of the biomedicine field due to their good biocompatibility and no toxicity or low toxicity in organisms [ 2 , 3 ], such as magnetic resonance imaging (MRI) [ 4 ], clinical diagnosis and the treatment of diseases [ 5 , 6 ], magnetic carriers for drug targeting [ 7 ], catalysis [ 8 , 9 , 10 , 11 , 12 ], immune assays [ 13 ], targeting photodynamic therapy [ 14 , 15 , 16 ], cell separation [ 17 ], DNA extraction [ 18 ], and so on. Therefore, the preparations and applications of iron oxide nanoparticles have attracted more and more researchers [ 19 , 20 ].…”

Light-Interacting iron-based nanomaterials for localized cancer detection and treatment

“…First, radio-luminescent FIBN produce a luminescence intensity proportional to the x-ray dose at which they are exposed. They could therefore potentially be used to monitor the doses of X-rays administered to a cancer patient, [148]. Secondly, an original detection system for cathepsin L was described.…”

Real-Time Tracking of Highly Luminescent Mesoporous Silica Particles Modified with Europium β-Diketone Chelates in Living Cells

“…Four major thermal transition peaks were emerged for Eu@MSP; two endothermic thermal transition peaks at 65.7 and 211 • C were allocated to T g and the crystalline melting temperature (T m ) of Eu@MSP, respectively. The exothermic peak at 307 • C can be assigned to thermal decomposition of P(Oct) 3 .…”

“…Nanoparticles have been widely used for nanomedicine applications [ 1 ]. Since it is possible to control the size and shape of the nanoparticles for their intrinsic and extrinsic characteristics such as an optical, electrical, and magnetic properties, the techniques for surface modifications and conjugation of biological ligands on nanoparticles have been increasing for bioimaging probes and theranostics both in in-vitro and in-vivo application [ 2 , 3 ]. Recently, mesoporous silica nanoparticles (MSN) have been noticed due to their physicochemical properties including consistent pore size, large surface area, and susceptibility of the surface functionality.…”
