The Golgi apparatus is an essential organelle constructed by the stacking of flattened
vesicles, that is widely distributed in eukaryotic cells and is dynamically regulated during cell …

Optical imaging is an indispensable tool for non-invasive visualization of biomolecules in
living organisms, thereby offering a sensitive approach for disease diagnosis and image …

Recent progress has shown that using wavelengths between 1,000 and 2,000 nm, referred
to as the shortwave-infrared or near-infrared (NIR)-II range, can enable high-resolution in …

Heptamethine indocyanines are invaluable probes for near-infrared (NIR) imaging. Despite
broad use, there are only a few synthetic methods to assemble these molecules, and each …

Small‐molecule‐based second near‐infrared (NIR‐II) activatable fluorescent probes can
potentially provide a high target‐to‐background ratio and deep tissue penetration. However …

Herein, we describe an energy balance strategy between fluorescence and photoacoustic
effects by sulfur substitution to transform existing hemicyanine dyes (Cy) into optimized …

Organic dyes in the excited singlet state (S1) decay via intersystem crossing (ISC) to the
triplet state, radiative dissipation as fluorescence, or nonradiative decay for thermal …

Conventional cyanine dyes with a symmetric structure are “always‐on”, which can easily
accumulate in the liver and display high liver background fluorescence, inevitably interfering …

Proteases are enzymes capable of catalyzing protein breakdown, which is critical across
many biological processes. There are several families of proteases, each of which perform …

Target-enabled bioorthogonal reaction and self-assembly of a small-molecule probe into
supramolecules have shown promise for molecular imaging. In this paper, we report a new …
