High-resolution imaging of 3D stray-field components with a Fe₃O₄ nanoparticle sensor

Abstract

Despite rapid advances in magnetic domain imaging techniques, high resolution imaging of 3D magnetic field components still faces a great challenge. Thus far, magnetic force microscopy has been utilized to...

Application and Method of Surface Plasmon Resonance Technology in the Preparation and Characterization of Biomedical Nanoparticle Materials

“…Several therapeutics for cancer, pain and infectious diseases have been successfully developed based on nanoparticles (particles with size range from 1 nm to 1000 nm), 1 including metal nanoparticles, lipid-based nanoparticles, as well as polymeric nanoparticles. 1–4 Nanoparticles have been frequently studied for application in various medical setting, including drug delivery, 5 targeted therapy, 6 , 7 imaging enhancement, 8 and early detection of disease. 9 To construct effective nanoparticle systems for biomedical applications, the nanoparticle surface characteristics and the interactions with biological systems need to be thoroughly characterized and tested.…”
