Alternating Shear Force of Respiration Regulates Cell Interactions of Fibroblasts and Macrophages to Promote Soft Tissue Integration of Chest Wall Polyetheretherketone Implants

Advanced Science, EarlyView.
Given that PEEK chest wall implants induce shear force at the soft tissue‐implant interface due to respiratory motion in the early in vivo post‐implantation stage. We confirmed that this mechanical stimulus triggers the PIEZO1/ITGB1/YAP1 signalling axis in L929 and the STAT6/p‐STAT6 pathway in RAW264.7, which in turn mediates adhesion and migration of ...

Time heterogeneity of the Förster radius from dipole orientational dynamics impacts single-molecule Förster resonance energy transfer experiments

Physical Review Research
Förster resonance energy transfer (FRET) is a quantum mechanical process governing the nonradiative energy transfer between coupled electric dipoles. Its strong distance dependence makes it a widely used as a “molecular ruler” in biology, chemistry, and ...

Energy Funneling in Quasi‐2D Ruddlesden–Popper Perovskites: Charge Transfer versus Resonant Energy Transfer

Advanced Photonics Research, 2022
The quasi‐2D Ruddlesden–Popper perovskites contain a collection of grains with inhomogeneous bandgaps, enabling efficient energy funneling from high‐bandgap grains (donors) to low‐bandgap grains (acceptors), leading to localization of carriers and ...

Mechanochemical Activation of a Bridged‐Exciplex Optical Force Probe

Advanced Science, EarlyView.
A bridged‐exciplex optical force probe is synthesized, switching from solvatochromic charge‐transfer emission in the latent state to intense locally excited emission upon activation. This dual photophysical response with additional changes in quantum yield and fluorescence lifetime enables precise environmental sensing and distinct optical readouts ...

Targeting the NR1D1–IGF2BP2–V‐ATPase Axis With Hybrid Nanovesicles Restores Macrophage Rhythms to Reverse Sepsis‐Induced Immunosuppression

Advanced Science, EarlyView.
Sepsis disrupts immune‐cell rhythms and weakens bacterial clearance. Biomimetic nanovesicles combining erythrocyte and inflammation‐activated macrophage membranes deliver siNR1D1 to dysfunctional macrophages, restoring the NR1D1–IGF2BP2–V‐ATPase pathway, circadian regulation, phagolysosomal acidification, and antimicrobial defense.

Ping–Pong Energy Transfer in a Heteroleptic Mixed‐Chromophore Coordination Cage

Angewandte Chemie, EarlyView.
Shape‐complementary assembly (SCA) opens access to Pd(II)‐based heteroleptic cages with mixed‐chromophore composition. Transient absorption studies, supported by calculations, point to a “ping–pong” excitation transfer mechanism, significantly extending excited‐state lifetimes and offering new design principles for light‐harvesting, emissive and ...
