Atherosclerosis (AS) is a crucial contributor to various cardiovascular diseases (CVDs), which seriously threaten human life and health. Early accurate recognition of AS plaques essential for the prevention treatment CVD. Herein, we introduce an AS-targeting nanoprobe based on near-infrared (NIR) persistent luminescence nanoparticles (PLNPs), developing highly sensitive NIR (PersL) plaque imaging technique successfully realizing early detection. The exhibits good monodispersity regular spherical morphology also owns exceptional PersL performance upon repetitive irradiation by biological window light. surface-conjugated antibody (anti-osteopontin) endowed excellent targeting ability foam cells within plaques. After intravenously injected into model mice, can accurately detect prior ultrasonography (US) magnetic resonance (MRI). Specifically, reveals at earliest 2 weeks, with higher signal-to-background ratio (SBR) up 5.72. Based this technique, has great potential applications in CVD, study pathogenesis, screening anti-AS drugs.

Abstract Hypoxia is an inherent physiologic barrier in the microenvironment of solid tumor and has badly restricted therapeutic effect photodynamic therapy (PDT). Meanwhile, photosensitizer (PS) agents used for PDT applications regularly encounter tiresome aggregation‐caused quenching that seriously decreases production efficiency cytotoxic reactive oxygen species. The aggregation‐induced emission (AIE) PSs with antiquenching characteristics aggregate state are considered as a promising tool achieving highly efficient applications, plenty studies have widely demonstrated their advantages various diseases. Herein, recent progress AIE battle antitumor hypoxia issue summarized practical molecular principles hypoxia‐overcoming highlighted. According to mechanism, these representative cases divided into low O 2 ‐dependent (type I PDT) tactics (mainly including ‐enrichment type II combination therapy). Furthermore, underlying challenges prospects proposed thus expect promote next development PSs.

Understanding the morphology and hemodynamics of cerebral vasculature at large penetration depths microscale resolution is fundamentally important to decipher brain diseases. Among various imaging technologies, three-photon (3P) microscopy significance by virtue its deep-penetrating capability submicron resolution, which especially benefits in vivo vascular imaging. Aggregation-induced emission luminogens (AIEgens) have been recognized be extraordinarily powerful as 3P probes. However, systematic studies on structure–performance relationship AIEgens seldom reported. Herein, a series has designed synthesized. By intentionally introducing benzene rings onto electron donors (D) acceptors (A), molecular distortion, conjugation strength, D–A can facilely manipulated. Upon encapsulation with DSPE-PEG2000, optimized are successfully applied for far-red/near-infrared-I (NIR-I, 700–950 nm) region under near-infrared-III (NIR-III, 1600–1870 excitation. Impressively, using mice an opened skull, within 1700 μm microvessel diameter 2.2 deep mouse were clearly visualized. In addition, blood vessels well-characterized.

The formation of atherosclerotic plaques is the root cause various cardiovascular diseases (CVDs). Effective CVD interventions thus call for precise identification to aid clinical assessment, diagnosis, and treatment such diseases. In this study, we introduce a dual-target sequentially activated fluorescence reporting system, termed in-sequence high-specificity dual-reporter unlocking (iSHERLOCK), precisely identify in vivo ex vivo. ISHERLOCK was achieved by creating three-in-one fluorescent probe that permits highly specific sensitive detection lipid droplets hypochlorous acid via "off-on" ratiometric readouts, respectively. Based on format, upregulated accumulation oxidative stress-the two hallmarks atherosclerosis (AS)-were specifically measured plaques, breaking through barrier tissue biopsy AS aiding effective stewardship.
