Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters

open access: yesAdvanced Functional Materials, EarlyView.
An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Modeling Early Metastatic Progression in Breast Cancer Using a Barrier‐Free, Perfusable Spheroid‐on‐a‐Chip Platform

open access: yesAdvanced Healthcare Materials, EarlyView.
Open‐port, barrier‐free microfluidic device for modeling early metastatic progression. A centrally positioned tumor spheroid releases invasive cells that migrate through the surrounding matrix and intravasate into endothelialized lateral channels.

Bioprinted Stiffness‑Tunable Pancreatic Microniches to Decode Early Tumor Initiation Mechanisms

open access: yesAdvanced Healthcare Materials, EarlyView.
Stiffness‐tunable GelMA microniches generated by microvalve bioprinting preserve wild‐type acinar identity while revealing a nonlinear, Kras‐dependent response to matrix mechanics. Intermediate stiffness promotes acinar‐to‐ductal metaplasia and proliferation, defining a permissive mechanical window.

Metaplastic breast carcinoma with extensive osseous differentiation: a case report

open access: yes, 2008
We present a case of a 77-year-old female who had a metaplastic breast carcinoma with extensive osseous differentiation. Her mammogram showed a largely calcified mass, but the pathology revealed that the calcification was ossification.

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

open access: yesAdvanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Charge‐Reversed Lipid Nanoparticles Enable Encapsulation of Pt2L4 Nanocages for In vivo Anti‐Cancer Treatment

open access: yesAdvanced Materials, EarlyView.
Charge‐reversed lipid nanoparticles (revLNPs) enable efficient encapsulation and delivery of cationic Pt2L4 nanocages. Encapsulation preserves potent anticancer activity while improving circulation, reducing vascular leakage, and promoting favorable biodistribution in vivo.

Synchronized Ablation of Multifocal Tumors Enabled by Multi‐Channel Lanthanide Nanocomposites

open access: yesAdvanced Materials, EarlyView.
A multi‐channel lanthanide nanocomposite enables orthogonal monitoring of tumor pH, glutathione, and temperature to guide customized therapy. Real‐time luminescence readouts determine a single irradiation protocol that synchronizes drug release and photothermal treatment, allowing efficient ablation of multifocal tumors while minimizing overtreatment ...
