Nanomagnetic Hyperthermia Sensitizes Gemcitabine Chemosensitivity in Pancreatic Cancer by Inhibiting HSPB1 to Amplify ACSL4‐Mediated Ferroptosis

open access: yesSmall, EarlyView.
ABSTRACT Pancreatic cancer, one of the most malignant solid tumors with the poorest prognosis, is commonly treated with gemcitabine (GEM)‐based systemic chemotherapy. However, chemoresistance remains a significant therapeutic challenge. Ferroptosis, a novel form of programmed cell death, has demonstrated exceptional susceptibility in chemoresistant ...

Magnetization states and switching in narrow-gapped ferromagnetic nanorings

open access: yes, 2012
We study permalloy nanorings that are lithographically fabricated with narrow gaps that break the rotational symmetry of the ring while retaining the vortex ground state, using both micromagnetic simulations and magnetic force microscopy (MFM).

Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 10, 13 March 2026.
A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng

Generating and Manipulating High Quality Factors of Fano Resonance in Nanoring Resonator by Stacking a Half Nanoring

open access: yesNanoscale Research Letters, 2017
We demonstrate the existence of Fano resonance spectral response in a system of nanoscale plasmonic resonant ring stacked by means of a half nanoring. Our proposed scheme exploits the stacked method under normal incidence to excite the subradiant mode ...

Core-shell Fe@FexOy nanoring system: A versatile platform for biomedical applications

open access: yesMaterials & Design, 2022
Iron oxide (maghemite and magnetite) nanoparticles are the most commonly used magnetic materials in nanomedicine because of their high biocompatibility. However, their low saturation magnetization (60–90 emu/g) limits their applicability. Here, we report

Switching of +/-360deg domain wall states in a nanoring by an azimuthal Oersted field

open access: yes, 2011
We demonstrate magnetic switching between two $360^\circ$ domain wall vortex states in cobalt nanorings, which are candidate magnetic states for robust and low power MRAM devices.

Interfacially Coupled and Synergistic Effect of Ag/Co3O4‐C Nanocomposites for Enhanced Oxygen Reduction (ORR) and Evolution (OER) Reaction

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
Ag/Co3O4–C nanocomposites display well‐resolved lattice fringes and synergistic Ag/Co3O4 heterointerfaces that enhance charge transfer and active‐site exposure. The structural design enables superior bifunctional ORR/OER performance in alkaline media by promoting efficient adsorption and turnover of oxygen intermediates within an optimized ...
