Abstract:

Monodispersed FePt nanoparticles with hydrophobic ligand were chemically synthesized and with controllable surface-functional properties. In order to enhance the saturation magnetization of FePt nanoparticles, the initial mole ratio of Fe to Pt precursors and reaction times were controlled to effectively increase magnetization due to the increased particle size and formation of FePt-Fe3O4 nanocomposites. The surface modification of FePt nanoparticles by using mercaptoacetic acid (C2H4O2S) as a phase transfer reagent through ligand exchange turned the nanoparticles hydrophilic, and the nanoparticles could water-dispersible. The streptavidin-biotin binding pair was used to conjugate with carboxylic acid (COOH) functional group on the surface of FePt nanoparticles that could be further functionalized to provide a biotin moiety for specific interactions with streptavidin protein.

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT)

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT) is an advanced Nuclear Magnetic Resonance (NMR) technique specifically designed to detect and enhance the signals of low-abundance nuclei, such as carbon-13 and nitrogen-15, in small molecules. The fundamental principle behind INEPT is the transfer of polarization from a more abundant and highly polarizable nucleus, typically hydrogen-1, to the low-abundance nucleus of interest. This process effectively boosts the NMR signal of the...

Ferromagnetism

Materials like iron, nickel, and cobalt consist of magnetic domains, within which the magnetic dipoles are arranged parallel to each other. The magnetic dipoles are rigidly aligned in the same direction within a domain by quantum mechanical coupling among the atoms. This coupling is so strong that even thermal agitation at room temperature cannot break it. The result is that each domain has a net dipole moment. However, some materials have weaker coupling, and are ferromagnetic at lower...
