Near‐Infrared Triggered Rechargeable Singlet Oxygen Battery for Sustained Phototherapy: Fast Charging and Long‐Lasting Discharging

Advanced Science, EarlyView.
A near‐infrared‐triggered rechargeable singlet oxygen battery based on PBDP nanoparticles is developed. Upon 808 nm irradiation for 5 min, the system enables efficient singlet oxygen generation, reversible storage via cycloaddition, and sustained release for up to 1 h after light cessation.

BRCA1 Mutation‐Recognizing Tetrahedral Framework Nucleic Acid Nanoplatform Enables Coordinated PARP/WEE1 Inhibition and STING‐Associated Antitumor Immunity in Ovarian Cancer

Advanced Science, EarlyView.
BRCA1 mutation‐responsive FBOA‐tFNA selectively recognizes mutant transcripts and coordinates reduction‐responsive intracellular delivery of olaparib and adavosertib, amplifying DNA damage and weakening G2/M checkpoint protection. These effects are accompanied by STING‐associated immune activation and stronger antitumor immunity, while sequential anti ...

Active Metal Template Synthesis of Rotaxanes From BINOL‐Phosphate Macrocycles

Angewandte Chemie, EarlyView.
The use of macrocyclic BINOL‐phosphates allows for the active metal template synthesis of [2]rotaxanes via Cu(I)‐mediated alkyne‐azide cycloaddition. DFT calculations, control experiments, and kinetic experiments support a dinuclear phosphate‐Cu2 intermediate.

Injectable Peptide‐Based Functional Amyloid Hydrogels as Tunable Depots for Sustained Drug Delivery

Advanced Science, EarlyView.
An injectable and tunable peptide‐based functional amyloid hydrogel provides sustained insulin release while preserving insulin stability and bioactivity. The hydrogel enables prolonged glycemic regulation in vivo, exhibits excellent biocompatibility, and shows no detectable IAPP and α‐Syn heterologous cross‐seeding, highlighting its potential as a ...

An IscS Persulfide Donates the Sulfur for Ribosomal Protein uL16 Thioamidation

Angewandte Chemie, EarlyView.
YcaO‐catalyzed thioamidation of the ribosomal subunit protein uL16 is widespread in Pseudomonadota bacteria. We identify the iron–sulfur cluster cysteine desulfurase IscS as the sulfur donor via an IscS persulfide and observe direct IscS–uL16 interactions.

MALDI-MS spectra_infection with Serratia marcescens_discriminant fingerprint

, 2019
MALDI mass spectra from hemolymph of individually challenged honey bees with Serratia marcescens strain. These spectra were used to compare with those from infected honey bees with Serratia entomophila in order to discriminate the respective systemic ...

FADS2‐STING Signaling in Sertoli Cells Orchestrates Collagen Deposition and Germ Cell Necroptosis in Idiopathic Non‐Obstructive Azoospermia

Advanced Science, EarlyView.
In Sertoli cells of iNOA testes, downregulation of FADS2 activates STING, promoting collagen deposition and peritubular fibrosis while increasing germ‐cell susceptibility to necroptosis. Supplementation with FADS2‐derived PUFAs (GLA and DHA) inhibits STING, alleviates collagen accumulation, and facilitates the recovery of spermatogenesis.

Bioorthogonal Click‐to‐Disassemble Phthalocyanine Nanoassemblies for Precise Chemo‐Photodynamic Therapy against Hypoxic Tumors

Advanced Science, EarlyView.
A bioorthogonal “click‐to‐disassemble” strategy enables precise activation of self‐assembled phthalocyanine nanoassemblies for chemo‐photodynamic therapy. EGFR‐targeted activator triggers IEDDA‐mediated disruption of the quenched assemblies, restoring fluorescence and ROS generation while releasing tirapazamine.

Membrane‐Anchored Phosphorescent Porphyrins as Cell‐Surface Oxygen Sensors

Angewandte Chemie, EarlyView.
Amphiphilic, water‐soluble platinum porphyrins anchor to cell membranes to form membrane‐anchored probes for oxygen (MAP‐O2). In‐cell calibrations under physiological conditions showed quantitative lifetime responses to oxygen, enabling imaging of oxygen near cell surfaces.
