Abstract Vascular stent implantation needs a rapid endothelialization to reduce morbidity and improve patient outcomes. A promising strategy enhance the artery wall healing is use site-specific drug targeting technique deliver required medication at site of injury. This work presents new concept using permanent magnet systems guide target functionalized magnetoresponsive nanocomposite clusters ...
The discovery of the quantum Hall (QH) effect led to the realization of a topological electronic state with dissipationless currents circulating in one direction along the edge of a two-dimensional electron layer under a strong magnetic field. The quantum anomalous Hall (QAH) effect shares a similar physical phenomenon to that of the QH effect, whereas its physical origin relies on the intrinsi...
The implant assisted magnetic targeted drug delivery system of Avilés, Ebner and Ritter is considered both experimentally (in vitro) and theoretically. The results of a 2D mathematical model are compared with 3D experimental results for a magnetizable wire stent. In this experiment a ferromagnetic, coiled wire stent is implanted to aid collection of particles which consist of single domain magn...
The field and spin dependence of the quasi-particle mass enhancements are examined in the paramagnetic and ferromagnetic states close to a quantum critical point. The down-spin quasi-particles are found to have heavier masses than the up-spin quasi-particles. It is also found that the spin dependence of the quasi-particles. It is also found that the spin dependence of the quasiparticle mass enh...
The low temperature magnetic properties of arrays of scanning tunneling microscope @TM) fabricated ferromagnetic particles have been studied as a function of their dimension using a novel high sensitivity Hall magnetometer. Iron deposits with controlled shape and nanometer scale diameters (-25 nm) are formed using a STM to decompose a metalorganic precursor [Fe(CO)s] in the active area of the m...
