TADF‐Active Tetrazole Luminophores for Visible‐Light Functionalization of Nanoparticles and Surfaces

open access: yesAngewandte Chemie, Volume 138, Issue 43, 19 October 2026.
A series of tetrazoles are reported that undergo 1,3‐dipolar cycloadditions with alkene and alkyne substrates, generating (dihydro)pyrazole products that exhibit thermally activated delayed fluorescence (TADF). The “photo‐click” reactivity of these tetrazoles is leveraged to functionalize nanoparticles and surfaces with TADF‐active chromophores ...

Sulfonated Hydroxyaryl-Tetrazines with Increased pKa for Accelerated Bioorthogonal Click-to-Release Reactions in Cells.

open access: yesAngewandte Chemie
Bioorthogonal reactions that enable switching molecular functions by breaking chemical bonds have gained prominence, with the tetrazine-mediated cleavage of trans-cyclooctene caged compounds (click-to-release) being particularly noteworthy for its high ...

Peptide‐Linked Bivalent Nanobody Constructs as Positive Allosteric Modulators of the Calcium‐Sensing Receptor

open access: yesBasic &Clinical Pharmacology &Toxicology, Volume 139, Issue 6, December 2026.
ABSTRACT We previously developed nanobodies acting as positive allosteric modulators (PAMs) of the calcium‐sensing receptor (CaSR). Here, we sought to develop more potent CaSR modulators by creating bivalent nanobody constructs using ‘tail‐to‐head’ peptide‐linker conjugation.

A Ruthenium(CAAC‐5) Olefin Metathesis Catalyst for Bioconjugation

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 45, 2 November 2026.
The aqueous instability of ruthenium catalysts restricts olefin metathesis in biological media. A Ru(CAAC‐5) complex bearing an aniline handle is reported that remains active under biologically relevant conditions and enables bioconjugation to proteins, peptides, and an artificial metalloenzyme, providing a robust platform for olefin metathesis in ...

Farnesyltransferase Enables Modular Assembly of Dual‐Functional Nanobody Conjugates for in Vivo Imaging of Inflammation

open access: yesAngewandte Chemie, Volume 138, Issue 42, 12 October 2026.
A modular farnesyltransferase‐based chemoenzymatic platform enables fast, site‐specific labeling of nanobodies for PET imaging of inflammation. CD11b‐targeted PET agents selectively image myeloid‐driven inflammation, while CD45‐targeted PET agents provide sensitive whole‐body immune mapping.
