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 ...

Self‐Amplified Activatable Fluorescent Probe for Early Diagnosis of Acute Kidney Injury and High‐Throughput Screening of Natural Protectants

Advanced Science, EarlyView.
The PS‐QRC nanoprobe employs L‐serine as a targeting ligand for kidney injury molecule‐1 (KIM‐1) to achieve accumulation in injured renal tissues. Upon activation by reactive oxygen species (ROS), it undergoes a self‐amplifying cascade to release fluorophores for near‐infrared fluorescence (NIRF) imaging, enabling ultra‐early diagnosis of acute kidney ...

Simultaneous Two- and Three-Photon Deep Imaging of Autofluorescence in Bacterial Communities

Sensors
The intrinsic fluorescence of bacterial samples has a proven potential for label-free bacterial characterization, monitoring bacterial metabolic functions, and as a mechanism for tracking the transport of relevant components through vesicles. The reduced

Dual‐Organelle Secretome Conjugation and Organ‐Uptake Tracking (DuO‐SCOUT) Enables Deep and Sensitive Mapping of the Secreted Proteins

Advanced Science, EarlyView.
A novel dual‐organelle proximity labeling platform, DuO‐SCOUT, decodes the complex landscape of systemic organ‐organ communication by capturing both classical and unconventional secretomes. Application in metabolic models maps the adipose‐to‐brain secretory relay, identifying selective extra‐hypothalamic sites for adipose‐derived factors and expanding ...

Engineered Cyanobacteria‐Hydrogel Microecological System for Oxygen Reprogramming Synergizes Immunomodulation With Anabolism in Osteoarthritis Therapy

Advanced Science, EarlyView.
An injectable cyanobacteria‐laden hydrogel enables light‐dependent oxygen metabolism engineering for osteoarthritis therapy. Photosynthetic oxygen release under red light irradiation suppresses synovial inflammation via HIF‐1α inhibition and M2 macrophage polarization, while respiratory oxygen consumption in darkness stabilizes chondrocyte HIF‐1α to ...

Low SLC8A1 in Colorectal Cancer Dictates Radiotherapy Resistance Through Calcium‐Dependent ANXA2+sEVs Driving M2 Polarization of TAMs

Advanced Science, EarlyView.
SLC8A1 deficiency in colorectal cancer cells increases intracellular calcium signaling, promoting the secretion of ANXA2‐enriched small extracellular vesicles. These vesicles reprogram tumor‐associated macrophages towards an M2 phenotype, which in turn fosters a tumor microenvironment conducive to radioresistance and is associated with poor patient ...
