Curvature and torsion in growing actin networks
, 2007 Intracellular pathogens such as Listeria monocytogenes and Rickettsia rickettsii move within a host cell by polymerizing a comet-tail of actin fibers that ultimately pushes the cell forward.

Advanced Functional Materials, EarlyView.This article presents a photo‐responsive nanoparticle platform that precisely triggers copper‐dependent cuproptotic cell death in (drug‐resistant) cancer cells. The system remains stable and inactive in the dark but releases cytotoxic species upon red‐light irradiation, achieving potent activity in drug‐resistant breast cancer cells.

Biophysical Regulation of Cellular Function in Bone
, 2022 Osteoporosis is the most prevalent bone disease and represents a major public health burden. Resulting from a reduction in bone quality and quantity, it can lead to fragility fractures with significant associated morbidity and mortality. Mechanical loading is a potent, albeit incompletely understood, anabolic stimulus that could lead to novel therapies

The Molecular and Cellular Biophysics of Probiotic Bacteria [PDF]
Biophysical Journal, 2015 Elie Metchnikoff proposed the use of probiotics a century ago. Probiotics regulate the integrity and functionality of gut microbiota. Currently, the scientific attention is more focused on the strain-specific features of probiotics and their use against pathogens or for the treatment of diseases and imbalances of the intestinal microbiota.

Advanced Functional Materials, EarlyView.A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

Roughness of Transmembrane Helices Reduces Lipid Membrane Dynamics
iScience, 2018 Summary: The dynamics of cellular membranes is primarily determined by lipid species forming a bilayer. Proteins are considered mainly as effector molecules of diverse cellular processes.

Advanced Functional Materials, EarlyView.We synthesized a novel IrCuOx/MnO2 heterostructure co‐doped with high‐valent W and Mo atoms, achieving exceptional acidic stability and high mass activity. Owing to the synergistic effects of structural and electronic modulation, cooperative charge redistribution occurs across both the interface and the lattice.

Photo-Induced Depletion of Binding Sites in DNA-PAINT Microscopy
Molecules, 2018 The limited photon budget of fluorescent dyes is the main limitation for localization precision in localization-based super-resolution microscopy. Points accumulation for imaging in nanoscale topography (PAINT)-based techniques use the reversible binding

A unified mechanistic model of niche, neutrality and violation of the competitive exclusion principle [PDF]
, 2012 The origin of species richness is one of the most widely discussed questions in ecology. The absence of unified mechanistic model of competition makes difficult our deep understanding of this subject.
