Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

open access: yesAdvanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Towards High‐Acuity Vision Restoration: Hybrid Retinal Prosthesis Composed of a High‐Density Multielectrode Array Integrated With Glutamatergic Cells

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a novel Hybrid Retinal Implant (HRI), composed of a high‐density electrode array integrated with glutamatergic neurons to overcome key limitations of current retinal prostheses. The significant reduction of activation threshold and of electrode cross‐talk yields in an improved spatial resolution.

Reconfigurable Microenvironments Uncover Mechano‐Sensing Timescales and Direct Cell Polarity

open access: yesAdvanced Functional Materials, EarlyView.
A synthetic DNA‐crosslinked cell culture matrix enables control over the mechanical microenvironment surrounding cells. Independent tuning of stiffness and stress relaxation uncovers distinct timescales of mechano‐sensing that regulate cell behavior.

Matrix mechano-sensing at the invasive front induces a cytoskeletal and transcriptional memory supporting metastasis

open access: yesNature Communications
The extracellular matrix (ECM) controls tumour dissemination. We characterise ECM organization in human and mouse tumours, identifying three regions: tumour body, proximal invasive front and distal invasive front.

Fluorescent Nanodiamonds Based Theranostic Platform for pH‐Sensitive Drug Delivery and Quantum Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A multifunctional nanodiamond platform enables pH‐triggered Diazoxide (DZX) delivery and quantum sensing of subcellular radical dynamics in triple‐negative breast cancer cells. Diamond relaxometry revealed reduced lysosomal radicals during DZX‐induced mitochondrial radical elevation, providing insights into redox modulation and organelle‐ resolved ...

Multifunctional, Flexible and Interactive PVDF Fibers with Tunable Conductivity via CNT Coatings for Sensing and Smart Textile Applications

open access: yesAdvanced Functional Materials, EarlyView.
A two‐step fabrication strategy combines electrospinning with electrophoretic deposition of carbon nanotubes to produce conductive, porous PVDF fiber mats. These flexible composites serve as multifunctional sensors, capable of detecting pressure, motion, respiration, and temperature.

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...
