Dispersive Electron-Transfer Kinetics of Rhodamines on TiO₂: Impact of Structure and Driving Force on Single-Molecule Photophysics

, 2016
The effects of dye structure, driving force of photoinduced electron transfer, and adsorption affinity on the dispersive electron-transfer dynamics of rhodamines on TiO2 films are investigated using single-molecule microscopy. The time-dependent emission

N, S Co‐Doped Carbon Quantum Dots‐Riboflavin Composite Photosensitizers for Enhanced Iontophoresis‐Assisted Corneal Cross‐Linking

Advanced Science, EarlyView.
This study explores the use of N, S co‐doped carbon quantum dots (NS‐CQDs) as carriers for riboflavin, creating NS‐CQDs‐RF composite photosensitizers. These composites improve riboflavin absorption, enhance ROS generation efficiency, and preserve corneal epithelium integrity.

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 ...

Understanding and Overcoming Antibody‐Drug Conjugate Resistance: Biological Mechanisms and Emerging Analytical Frameworks in Breast Cancer

Advanced Science, EarlyView.
Antibody–drug conjugates (ADCs) transform breast cancer therapy, yet resistance limits their durability. Emerging evidence reveals that ADC failure is not solely tumor‐intrinsic but shaped by dynamic tumor–microenvironment interactions that alter drug delivery, processing, and response.

Multi‐Enzyme Mimetic Molybdenum Nitride Nanozymes Reshape Subgingival Microenvironment for Synergistic Periodontitis Therapy via ROS Regulation and Microbiome Remodeling

Advanced Science, EarlyView.
ABSTRACT Periodontitis, a chronic inflammatory disease initiated and sustained by plaque microorganisms and host immune response, remains an intractable oral disease and a leading cause of tooth loss worldwide. Traditional mechanical debridement and adjunctive antibiotic or antiseptic therapy often shows limited efficacy due to the complex anatomical ...

Dual‐Responsive Dynamic Covalent Bond‐Based Assembly of Lipid‐Nanozyme Systems via Multi‐Target Synergy and Efficient Target Enrichment for Ischemic Stroke Therapy

Advanced Science, EarlyView.
This system adopts a biomimetic phospholipid structure, covalently binding iNOS inhibitors, neuroprotective agent PCA and vitamin E derivatives through pH/ROS dual‐responsive bonds, and assembles them with Prussian blue nanozyme to form PBB@AHA. It can efficiently penetrate the blood‐brain barrier and simultaneously release multiple active components ...

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...
