Structures, electronic and magnetic properties of Mn and Mn2 doped stoichiometric (GaO)n clusters with n = 1−7 are studied in the framework of density functional theory. Doping of a Mn atom is found to be energetically favorable
in (GaO)n clusters and the equilibrium configurations are found to be determined by the metal–oxygen interactions. Mn prefers to maximize
the number of Mn–O bonds by selecting a Ga site in the cluster which increases its coordination with oxygen. Addition of a
Mn atom in Mn(GaO)n clusters results into the ground state to be either ferromagnetic or antiferromagnetic depending on the Mn coordination number
and the Mn–Mn bond-length in the given Mn2(GaO)n cluster. 相似文献
A rational design of magnetic capturing nanodevices, based on a specific interaction with circulating tumor cells (CTCs), can advance the capturing efficiency and initiate the development of modern smart nanoformulations for rapid isolation and detection of these CTCs from the bloodstream. Therefore, the development and evaluation of magnetic nanogels (MNGs) based on magnetic nanoparticles and linear thermoresponsive polyglycerol for the capturing of CTCs with overexpressed transferrin (Tf+) receptors has been presented in this study. The MNGs are synthesized using a strain‐promoted “click” approach which has allowed the in situ surface decoration with Tf–polyethylene glycol (PEG) ligands of three different PEG chain lengths as targeting ligands. An optimal value of around 30% of cells captures is achieved with a linker of eight ethylene glycol units. This study shows the potential of MNGs for the capture of CTCs and the necessity of precise control over the linkage of the targeting moiety to the capturing device.
