Germanium‐Based Long‐Conjugation Xanthene Fluorophores for Bioimaging in Optimal NIR‐II Sub‐Window

Aggregate, EarlyView.
An NIR‐II dye (EGe5) integrates germanium‐enhanced vibrational suppression and extended conjugation, achieving unprecedented brightness in the optimal NIR‐IIx sub‐window. This design enables high‐contrast visualization of intestinal vasculature and renal labeling, overcoming traditional signal limitations. The tailored spectral properties highlight its

Intelligent Theranostic Systems Enabled by Aggregation‐Induced Emission in Precision Medicine

Aggregate, EarlyView.
Aggregation‐induced emission (AIE) luminogens are driving a new generation of intelligent theranostic systems that integrate high‐fidelity imaging and multifunctional therapy. This review highlights how AIEgens, through restriction of intramolecular motion (RIM), enable deep‐tissue NIR‐II imaging, ultrasensitive biosensing, CRISPR‐assisted gene ...

Establishment of a novel alloxan‐induced rabbit model exhibiting unique diabetic retinal neuropathy features assessed via ERG + VEP

Animal Models and Experimental Medicine, EarlyView.
Study workflow. Neuroretinal changes were observed in alloxan‐induced diabetic rabbits, while the retinal vasculature remained unaffected, indicating the successful establishment of a diabetic neuroretinal model. Abstract Background Diabetic retinal neuropathy (DRN) leads to significant visual impairment; however, no existing animal model fully ...
