Synthesis, Biological Activity, and Molecular Dynamics Simulations of LNA‐Charge Neutral Linkages for Enhanced Splice‐Switching Antisense Oligonucleotides

Angewandte Chemie, EarlyView.
Splice‐switching oligonucleotides are used to treat severe genetic conditions including Duchenne Muscular Dystrophy, but new chemistries are urgently required to improve their efficacy. In this work locked nucleic acid (LNA) is coupled to different charge neutral DNA backbones which are studied by structural, thermodynamic, and biological methods.

Effects of Varying Deposition Rates of a Carbazole and Triazine Derivative on Its Tunable Emission and Charge‐Transporting Properties Beneficial for Efficient Red Electroluminescent Devices

Advanced Optical Materials, EarlyView.
The highly efficient and ultrafast thermally activated delayed fluorescence (TADF) behavior of the bipolar derivative of carbazole and triazine stems from the high‐lying triplet states (hot TADF), which has a direct impact on the overall triplet harvesting of guest‐host mixtures.

Breaking Bonds by Light: The Absorbance–Fragmentation Paradox

Chemistry – A European Journal, Volume 31, Issue 46, August 18, 2025.
Although octupolar and quadrupolar DMAQ‐derived probes showed superior ε and two‐photon absorption cross‐section (σ2) values relative to the dipolar one (1), the fragmentation efficiency exhibited inverse trend, and 1 emerged as the most effective caging group achieving Q = 12% quantum yield with σ2 = 86 GM and uncaging cross‐section δu = 10.2 GM at ...

Enhancing the Potency of Growth Factor‐Mimicking Peptides via Cross‐Presentation With Integrin Ligands

Journal of Biomedical Materials Research Part A, Volume 113, Issue 7, July 2025.
ABSTRACT Growth factors enhance survival and integration of transplanted Mesenchymal Stromal Cells (MSC), but successful supplementation often requires supraphysiological growth factor doses, risking off‐target effects. Short peptide mimics like the knuckle epitope (KE) of Bone Morphogenetic Protein 2 (BMP‐2) can be covalently immobilized to ...

What can we Learn from Quantum Convolutional Neural Networks?

Advanced Quantum Technologies, Volume 8, Issue 7, July 2025.
Quantum Convolutional Neural Networks have been long touted as one of the premium architectures for quantum machine learning (QML). But what exactly makes them so successful for tasks involving quantum data? This study unlocks some of these mysteries; particularly highlighting how quantum data embedding provides a basis for superior performance in ...

Luminescent Lanthanide Complexes with Fluorinated Heterocycles as Light‐Harvesting Antennae

European Journal of Inorganic Chemistry, Volume 28, Issue 14, May 23, 2025.
The luminescence of trivalent lanthanide (Tb, Eu, Sm, Dy) coordination compounds was optimized. The electronic properties of the light‐harvesting antenna were modulated by regioselective fluorination and trifluoromethylation. The effects of the coordination geometry of the metal ion and the linker connecting the carbostyril and the metal‐binding site ...

Fluorescent Carbazole‐Derived Aza[5]Helicenes: Synthesis, Functionalization, and Characterization

Chemistry – A European Journal, Volume 31, Issue 27, May 14, 2025.
Variously substituted indolophenanthridines, indolocarbazoles, and cinnolinocarbazoles synthesized by ortho fusion from teraryl precursors show significant Stokes shifts, especially for the protonated states of indolophenanthridines and cinnolinocarbazole.

Elucidating the Supramolecular Interaction of Positively Supercharged Fluorescent Protein with Anionic Phthalocyanines

Advanced Biology, Volume 9, Issue 5, May 2025.
Positively supercharged mGreenLatern protein is self‐assembled electrostatically with negatively charged zinc phthalocyanines to yield bio‐based photoactive materials in aqueous media. The addition of phthalocyanines results in the formation of large complexes fully quenching of the protein fluorescence. The results indicate an energy transfer from the
