Magnetic nanoprobe that is super paramagnetic iron
oxide nanoparticles (SPIONs-C959) bonded with folic acid was produced firstly.
The team, led by Rex Moats, PhD, and Karen Aboody, MD, said their method, which involves "pre-loading" the cells before transplantation with ultra-small, super paramagnetic iron
oxide nanoparticles that can then be detected via magnetic resonance imaging (MRI), has been approved for clinical trials in humans and has the potential to greatly accelerate the search for new treatments for deadly brain tumors and other diseases.
For example, magnetic osteoblast cells labeled with super paramagnetic iron
oxide (SPIO) may be used for in-vivo imaging of osteoblasts using magnetic resonance imaging (MRI) a common clinical imaging procedure.
The latter cells are labeled with super paramagnetic iron
oxide (SPIO) and may be used for in-vivo imaging of chondrocytes using MRI (magnetic resonance imaging) a common clinical imaging procedure.
MRI labels include paramagnetic iron
oxide and manganese oxide.
2]-weighted MRI does not use a refocusing pulse, "so the dephasing caused by the paramagnetic iron
is accentuated by the [T*.
Considering these properties, we used super paramagnetic iron
oxide (nanomag-D-SPIO 20nm) with COOH group on the surface, for conjugation to a humanized anti her2/neu monoclonal antibody (Herceptin) as a cancer targeting antibody.
The paramagnetic iron
indicates two sites and the magnetic iron apparently shows a distribution of sites.
In particular, dry chemistry coagulation testing at the POC with paramagnetic iron
oxide particles (PIOP) has provided alternatives to testing previously done only in the laboratory and has opened the door to convenient fibrinolytic testing [2-4].
Elaborating on the procedure of the research, Dr Arsalani said, "We first synthesized super paramagnetic iron
oxide nanoparticles by using the common and cost-effective method of co-precipitation in an aqueous environment.
Each TAS PT-One test cartridge contains lyophilized thromboplastin from human placenta, calcium chloride, and buffers coated with paramagnetic iron
oxide particles (PIOP).
