Silicon Substitution in Oxazine Dyes Yields Near-Infrared Azasiline Fluorophores That Absorb and Emit beyond 700 nm

, 2018
Exchanging the bridging oxygen atom in rhodamine dyes with a dimethylsilyl group red-shifts their excitation and emission spectra, transforming orange fluorescent rhodamines into far-red Si-rhodamines.

Radical‐Mediated In Situ Fluorescence Dye Deposition: A Simple Interfacial Signal Amplification Reaction for Ultrasensitive Immunoassay on Barcode Beads

Advanced Science, EarlyView.
A radical‐mediated in situ fluorescence dye deposition (RIFD) reaction containing merely three elements of beads, dyes, and radicals is discovered for the first time, and its underlying mechanism is elucidated. This simple RIFD enables the interfacial and ultrafast deposition of free dyes onto barcode beads, serving as a powerful signal amplification ...

Black Hole Quencher‐Enhanced Plasmonic Photothermal Conversion

Advanced Science, EarlyView.
Researchers have developed a universal method to boost plasmonic photothermal conversion by attaching black hole quencher (BHQ) molecules to matched metal nanostructures. This hybrid approach increases efficiency by roughly threefold, reaching up to 69.1% in the near‐infrared‐II window.

Fast, Bright, and Reversible Fluorescent Labeling of Rhodamine-Binding Proteins [PDF]

Rhodamine dyes conjugated to targeting ligands can yield exceptionally bright fluorescent probes for live-cell imaging. However, the limited permeability of such rhodamine derivatives restricts their broader applications, particularly in vivo.

Metal‐Half‐Salen Chemistry for One‐Pot Mineralization on Hydrophobic Polymer Membranes

Advanced Science, EarlyView.
Here we report a versatile one‐pot synthetic strategy for organic–inorganic composite membranes, which leverages a metal half‐Salen system to precisely govern the competing kinetics of coordination and hydrolysis. In contrast to conventional two‐step metal‐phenol chemistries, our integrated approach substantially simplifies the fabrication process ...

Switchable Rhodamines for Molecular Electronics

Journal of the American Chemical Society
Rhodamines are widely used in bioimaging as fluorogenic sensors that reversibly switch between homoconjugated lactone (dark) and conjugated zwitterionic (bright) states in response to external stimuli. Here we transpose the lactone–zwitterion equilibrium (KL–Z) concept from fluorescence microscopy to molecular electronics to create the first rhodamine ...

Synergistic p53 Pathway Activation Through Sono‐Gene Therapy Induced by Ultrasound‐Triggered Theranostic Mesoporous Nanoparticles

Advanced Science, EarlyView.
Schematic representation of ultrasound‐mediated ICG/siCD24@MSN‐LCD from nanostructure to synergistic sono‐gene therapy. This nanoplatform targets ASGPR via the LCD shell, which dissociates to release loaded ICG and siCD24. The core mechanism involves ultrasound‐guided sonodynamic therapy by ICG and CD24 knockdown by siCD24, both activating the p53 axis
