Theranostic nanoplatform for high‐performance dual‐modal magnetic resonance imaging‐guided therapy of orthotopic hepatocellular carcinoma

open access: yesBMEMat, EarlyView.
This article introduces a biomimetic Mn‐doped polydopamine nanoplatform (HAMM NPs) coated with cancer cell membranes. It enables targeted hepatocellular carcinoma theranostics via T1/T2 dual‐mode magnetic resonance imaging and tumor microenvironment‐triggered sonodynamic therapy/chemodynamic therapy, achieving potent antitumor efficacy in subcutaneous ...

Paradigm shift in wearable bioelectronics: Drift‐free organic field‐effect transistor biosensors enabled by diode‐connected pairs

open access: yesBMEMat, EarlyView.
Organic field‐effect transistor (OFET)‐based biosensors are promising for wearable technology due to their flexibility and low cost, but their susceptibility to signal drift from mechanical stress and environmental factors remains a challenge. Here, we highlight a novel strategy that eliminates these drifts through a fundamental redesign of the OFET ...

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

Integrated spherical nucleic acid nanoreactor mobilizes targeted PD‐L1 proteolysis and cuproptosis for robust breast cancer immunotherapy

open access: yesBMEMat, EarlyView.
This study provides an integrated spherical nucleic acid nanoreactor (denoted as AMCuD) for targeted PD‐L1 degradation and chemo‐dynamically enhanced cuproptosis to synergically elicit robust immunotherapy against the triple‐negative breast cancer (TNBC) growth, recurrence and metastasis.

ESG Assurance and Dividends: Evidence From 18 Countries in Africa

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines the impact of environmental, social and governance (ESG) assurance on a firm's dividend payout policies within the unique African context. Using a staggered difference‐in‐differences (DiD) model, this study examines how voluntary third‐party assurance of ESG reports influences firms' dividend payout policies compared to ...
