Mechanical Stimuli‐Induced Manipulation of Malignant Behavior in Bioprinted Cancer Microtissues via PI3K/NF‐κB Activation

Advanced Science, EarlyView.
A mechanically tunable ECM platform is created by integrating dECM–alginate matrices with in‐bath tumor printing. The mechanically tunable ECM environment drives tumors to acquire hypoxia, mechanotransduction signaling, metastatic traits, and drug‐resistant phenotypes that collectively promote malignant transformation.

Microenvironment‐Guided Evolution of ssDNA‐SWCNT Probes for Selective Recognition of Aggressive Prostate Cancer Phenotypes

Advanced Science, EarlyView.
Random ssDNA–SWCNT(single strand DNA‐single walled carbon nanotube) library is functionally screened and evolved using high‐throughput 3D prostate tumor spheroids via iterative positive and negative selection, enabling the identification of NIR‐II fluorescent ssDNA‐SWCNT nanoprobe specific for prostate cancer.

Residual entropy in a model for the unfolding of single polymer chains

, 2007
We study the unfolding of a single polymer chain due to an external force. We use a simplified model which allows to perform all calculations in closed form without assuming a Boltzmann-Gibbs form for the equilibrium distribution.

Immunomodulatory Fibrous Scaffold with Dual Enzyme‐Mimic Activities Prevents Postsurgical Tumor Recurrence

Advanced Science, EarlyView.
A MnOx nanozyme‐functionalized electrospun fibrous scaffold is developed for postoperative therapy by leveraging its intrinsic physicochemical and immunomodulatory properties. Integrating POD‐ and CAT‐like activities, the scaffold induces immunogenic cell death, alleviates hypoxia, and reverses immunosuppression, while simultaneously recruiting and ...

Nitrogen‐Boosted H2O2 Production of Arginine‐Polyphenol Nanozyme Drives Oxidative Eustress for Hair Regeneration

Advanced Science, EarlyView.
PEA nanoenzymes are assembled from L‐arginine and EGCG. The nitrogen element in arginine enhances the thermodynamic feasibility of H2O2 production through PEA's oxygen reduction catalysis, enabling nitrogen‐dependent H2O2 release. Intradermal delivery of PEA via microneedles promotes efficient H2O2 synthesis, thereby stimulating regrowth in telogen ...
