Super-resolution imaging has rapidly emerged as an optical microscopy technique, offering advantages of high resolution over the past two decades; achieving improved requires significant efforts in developing super-resolution agents characterized by brightness, contrast and sensitivity to fluorescence switching. Apart from technical requirements systems algorithms, relies on fluorescent dyes with special photophysical or photochemical properties. The concept aggregation-induced emission (AIE) was proposed 2001, coinciding unprecedented advancements innovations technology. AIE probes offer many advantages, including brightness aggregated state, low background signal, a larger Stokes shift, ultra-high photostability, excellent biocompatibility, making them highly promising for applications imaging. In this review, we summarize progress implementation methods provide insights into mechanism AIE-based imaging, switching resulting photochemically-converted emission, electrostatically controlled specific binding-regulated emission. Particularly, principle been achieve spontaneous switching, expanding selection application scenarios probes. By combining molecular design, some comprehensive facilitate AIEgens (AIE-active molecules)

Aggregation-Induced Emission Luminogens for Latent Fingerprint Detection

Chemical Communications, Год журнала: 2024, Номер 60(64), С. 8314 - 8338

Опубликована: Янв. 1, 2024

For over a century, fingerprints have served as pivotal tool for identification of individuals owing to their enduring characteristics and easily apparent features, particularly in the realm criminal investigations. Latent (LFPs) are "invisible fingerprints" that most commonly available at crime scenes require rapid, selective, sensitive, convenient method detection. However, existing fingerprint development techniques harbour limitations, prompting exploration novel approaches prioritize investigator safety environmental sustainability. Leveraging unique photophysical properties aggregation-induced emission luminogens (AIEgens) has emerged promising strategy on-site analysis LFP visualization. In this highlight, we presented comparative various AIEgens (organic compounds, metal complexes, nanoparticles, polymers) detection LFPs. Through examination, insights into efficiency potential applications AIE-based provided. addition, several strategies been proposed circumventing limitations AIEgens. We hope highlight article will encourage more researchers investigate detection, contributing forensic science.

Bioconjugate Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

Fluorescence imaging technology is playing increasing roles in modern personalized and precision medicine. Thanks to their excellent photophysical properties, organic luminogens featuring aggregation-induced emission (AIE) characteristics (AIEgens) have attracted considerable attention over the past two decades. Because of superior biocompatibility, ease processing functionalization, water solubility, high responsiveness, exceptional signal-to-noise ratio (SNR) for biotargets, AIE bioconjugates, formed by covalently linking AIEgens with biomolecules, emerged as an ideal candidate bioapplications. In this review, we summarize progress preparation, application bioconjugates last five years. Moreover, challenges opportunities are also briefly discussed.
