Investigating the structural biofunctionality of antibodies conjugated to magnetic nanoparticles.

چکیده
We present the synthesis of trastuzumab-functionalized pegylated iron oxide nanoparticles and provide an FTIR-based approach to gain a direct evidence of the actual conservation of the native structure of conjugated antibody. Their target-selectivity to specific cancer cell receptors has been also assessed.

Measurement of C- Reactive Protein (CRP ) Using Magnetic Nanobeads Add ELISA
Abstract Background and Objective: Magnetic nanobeads have a large surface- area-to-volume ratio, which is used for immobilized antibody. Using nanoparticles could increase the amount of antibodies in surface in comparison to ELISA. We investigated the ability of magnetic nanobeads to evaluate CRP by colorimetric method and compared the results with ELISA. Material and Methods: This stud...
متن کاملDetection of Her2 Levels in Cancerous Cells Based on Iron Oxide Nanoparticles
In this study, we synthesized Herceptin conjugated magnetic nanoparticles (HMNs) as an alternative probe to discover the levels of HER2 (Human epidermal growth factor receptor-2) in the surface of cells. These nanoparticles can be used by magnetic resonance imaging (MRI) (non-invasive methods) for screening the patients with HER2 positive or negative tumors. Dextran coated iron oxide nanopartic...
متن کاملSPION Conjugated Curcumin Nano-Imaging Probe: Synthesis and Bio-Physical Evaluation
In this work, we investigate the loading and conjugation of Curcumin on oleic acid (OA) and citric acid (CA) functionalized iron oxide nanoparticles and its applications in improving contrast in MRI. Magnetic iron oxide nanoparticles (Fe3O4, MNPs) synthesized using the co-precipitation method and characterized by XRD, DLS, FT-IR, VSM and SEM. FT-IR results confirmed functionalization with oleic...
