Enhancing Magnetic Hyperthermia at the Cell Membrane by Anchoring 92R‐Functionalized Magnetic Nanoparticles to Low‐Endocytic CCR9 Surface Receptors

Advanced Healthcare Materials, EarlyView.
We present a strategy to enhance magnetic hyperthermia therapy by modulating nanoparticle–cell interactions. Antibody‐functionalized magnetic nanoparticles targeting the low‐internalizing CCR9 receptor enable spatially controlled membrane anchoring, reducing aggregation and maximizing heat generation under alternating magnetic fields.

Effects of Magnetite Nanoparticles on Soybean Chlorophyll [PDF]

Environmental Science & Technology, 2013
Nanoparticles (NPs) have emerged as one of the most innovative and promising application in agriculture. Since plants are recognized as essential component of all ecosystems, the effects of NPs on plants may pave a new insight to the ecosystems. Here, uptake and translocation of superparamagnetic iron oxide NPs (SPIONs), with various surface charges ...

Solution‐Processed Spin‐Polarized Light‐Emitting Diodes of Colloidal Quantum Wells and Magnetic Nanoparticles

Advanced Optical Materials, EarlyView.
All‐solution‐processed spin‐LEDs based on colloidal Fe3O4 nanoparticles and CdSe/CdZnS core/shell CQWs that allows for polarization modulation of electroluminescence are fabricated. With these devices, electrical injection of spin‐polarized carriers from the Fe3O4 nanoparticle layer into the CdSe/CdZnS CQWs is demonstrated, realizing circularly ...
