Interactions of hydrophilic quantum dots with defect-free and defect containing supported lipid membranes

Colloids and Surfaces B: Biointerfaces Volume 210, February 2022, 112239 Quantum dots (QDs) are semiconductor nanoparticles with unique optical and electronic properties, whose interest as potential nano-theranostic platforms for imaging and sensing is increasing. The design and use of QDs requires the understanding of cell-nanoparticle interactions at a microscopic and nanoscale level. Model systems such En savoir plus surInteractions of hydrophilic quantum dots with defect-free and defect containing supported lipid membranes[…]

Cell monolayers sense curvature by exploiting active mechanics and nuclear mechanoadaptation

Nature Physics (2021) The early development of many organisms involves the folding of cell monolayers, but this behaviour is difficult to reproduce in vitro; therefore, both mechanistic causes and effects of local curvature remain unclear. Here we study epithelial cell monolayers on corrugated hydrogels engineered into wavy patterns, examining how concave and convex curvatures affect En savoir plus surCell monolayers sense curvature by exploiting active mechanics and nuclear mechanoadaptation[…]
