Biomimetic Nanoplatform for Fibrosis Remodeling and Anti‐PD‐1 Potentiation via Cu+/Ca2+ Ion Dysregulation and TGF‐β Inhibition in PDAC

open access: yesAdvanced Science, EarlyView.
A biomimetic nanoplatform (RPm@CC‐LY) remodels fibrotic stroma via sustained TGF‐β inhibition, triggers oxidative stress and apoptosis through Cu+‐mediated Fenton chemistry and Ca2+ overload, and reprograms macrophages and dendritic cells to boost CD8+ T cell infiltration.

pH‐Responsive Nanoplatform‐Mediated Lipid Hijacking and Metabolic Collapse for Synergistic Starvation‐Immunotherapy

open access: yesAdvanced Science, EarlyView.
A pH‐responsive ZIF‐8/2‐DG@Cu‐TA nanoplatform orchestrates multifaceted metabolic disruption for synergistic starvation‐immunotherapy. Acid‐triggered 2‐DG release blocks glycolysis, while Zn2+ overload induces mitochondrial dysfunction. Concurrently, Cx43‐mediated gap junctions redirect lipid droplets from tumor cells to cancer‐associated fibroblasts ...

Nanocatalytic Immunotherapy Targeting Tumor‐Resident Intracellular Bacteria for Triple‐Negative Breast Cancer Treatment and Metastasis Suppression

open access: yesAdvanced Science, EarlyView.
Bacteria residing within tumor cells contribute to breast cancer progression, but few therapies target their elimination. FeSe2 nanosheets coated with cancer cell membranes accumulate in tumors and generate reactive oxygen species under ultrasound, killing tumor cells and their harbored bacteria at the same time.

Covalent Immobilisation of PVA‐MA Hydrogels on Plasma‐Activated Coatings: Achieving Superior Adhesion by Reagent‐Free Formation of a Nanoscale Primer Layer

open access: yesAdvanced NanoBiomed Research, EarlyView.
Robust attachment of hydrogels to solid substrates is critical to success in cell culture where hydrostatic and contractile forces can contribute to delamination of weakly adhered gels. This novel approach forms a nanometer‐scale, reagent‐free hydrogel primer layer to provide improved resistance to delamination of subsequent bulk hydrogel layers in a ...

Novel spin labels for EPR investigation of protein–peptide interactions

open access: yes
reservedSite-directed spin labeling (SDSL) combined with electron paramagnetic resonance (EPR) spectroscopy has emerged as a well-established method that can provide specific information about the structure, dynamics, and conformational changes of ...

Ultrasound-triggerennd piezocatalytic conductive Guar gum/PEDOT: PSS/BTO composite hydrogels for bacterial-infected skin wound healing

open access: yesNano TransMed
Open skin wounds are susceptible to infections by multidrug-resistant bacteria, which can lead to delayed wound healing or worsening of symptoms. Therefore, there is an urgent need to develop a comprehensive strategy that addresses bacterial infections ...

Homologous tumor‐targeting biomimetic nanozyme for synergistic NIR‐II photothermal and chemodynamic therapy

open access: yesBMEMat, EarlyView.
Studies reveal that a biomimetic nanoplatform based on a cancer cell membrane‐camouflaged Au‐MnOx nanozyme (Au‐MnOx@CCM) can achieve synergistic antitumor therapy by combining NIR‐II mediated PTT with enhanced CDT, offering a promising strategy for precise and efficient tumor therapy. Abstract The therapeutic potential of nanozyme‐mediated chemodynamic

On polynomial EPr matrices

open access: yes, 1992
This paper gives a characterization of EPr-λ-matrices. Necessary and sufficient conditions are determined for (i) the Moore-Penrose inverse of an EPr-λ-matrix to be an EPr-λ-matrix and (ii) Moore-Penrose inverse of the product of EPr-λ-matrices to be an ...
