Inorganic Nanomaterials can Promote or Inhibit Tumor Metastasis Depending on Tumor Microenvironment Composition

open access: yesAdvanced Science, EarlyView.
As engineered nanomaterials gain prominence in cancer imaging and therapy, understanding their impact on tumor progression becomes increasingly critical. We demonstrate that gold and silica‐coated gold nanomaterials can either suppress or enhance breast cancer metastasis through distinct tumor microenvironment interactions, while identifying ...

Defect‐Engineered BiO2‐X Nanosheets Mediate Sono‐Thermomechanical ECM Remodeling for Hepatocellular Carcinoma Immunotherapy

open access: yesAdvanced Science, EarlyView.
Herein, an ultrasound‐responsive BiO2‐X/siFn1 nanoplatform is developed to overcome anti‐PD‐1 resistance in hepatocellular carcinoma. Upon ultrasound irradiation, the platform downregulates fibronectin expression, while its sonothermal effect softens the dense extracellular matrix and activates antitumor immunity in the tumor microenvironment, thereby ...

AI‐Assisted Tumor Boundary Delineation via Targeted Ultrasmall Iron Oxide Nanoprobe for High‐Contrast HER2‐Positive Tumor Imaging

open access: yesAdvanced Science, EarlyView.
A novel targeted and pH‐responsive MRI contrast agent was integrated with a 3D nnU‐Net deep learning framework to enable accurate delineation of tumor boundary morphology in HER2‐positive breast cancer imaging. ABSTRACT Breast cancer continues to be a leading cause of cancer‐related mortality in women globally, where precise diagnosis and clear tumor ...

Towards Metabolic Organic Radical Contrast Agents (mORCAs) for Magnetic Resonance Imaging

open access: yesMolecules
We report two conjugates of gem-diethyl pyrroline nitroxide radicals with D-mannosamine as potential metabolic organic radical contrast agents, mORCAs, circumventing the need for biorthogonal reactions.
