An Adaptive Metasurface for Adjustable Magnetic Resonance Imaging Enhancement at 3 T and 7 T: A Feasibility Study

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultra‐high field (≥ 7 T) and 3 T MRI suffer from B1+ inhomogeneity and signal loss. Conventional metasurfaces that mitigate B1+ inhomogeneity and improve image SNR are “fixed” in nature and designed for a single Larmor frequency. This study demonstrates the feasibility of an adaptive metasurface utilizing voltage‐controlled capacitors ...

Responsive nanoheterojunctions for built‐in electric field‐promoted cascade tumor targeting and cuproptosis‐based therapy

open access: yesResponsive Materials, EarlyView.
Nanoheterojunctions have been synthesized as responsive biomaterials for cascade targeting of tumor cells and mitochondria, ROS‐mediated apoptosis and Cu‐promoted cuproptosis. And drug‐device‐field integration as an advanced paradigm of tumor treatment was employed for photo‐triggered tumor cell elimination in vitro and lesion eradication in vivo ...
