Self‐Calibrating Ratiometric DNA Aptamer Probe for Quantitative ATP Imaging in Living Cells

open access: yesChemistry – A European Journal, EarlyView.
We developed the RFA–ECHO probe, an internally calibrated ATP sensor that remains responsive across millimolar ATP levels. Its self‐correcting Cy5/ECHO ratio ensures accurate quantification independent of probe uptake. Compared with FRET‐based sensors, it yields a robust ratiometric shift, distinguishing high‐ATP cancer cells from normal ones, enabling

Two‐Step Synthesis of a Chiral Fluorinated Alcohol With Silica‐Supported Enzyme RrADH in Batch and Continuous Flow Mode

open access: yesChemistry – A European Journal, EarlyView.
A two‐step process was transferred from batch to flow mode for the synthesis of (R)‐2‐fluoro‐1‐phenylethanol as a benchmark, consisting of a decarboxylative fluorination in aqueous media, followed by an enantioselective biocatalytic reduction of the prochiral intermediate with RrADH immobilized on silica supraparticles.

Mini‐Hairpin DNA: Extraordinarily Stable Structure and Its Applications

open access: yesChemistry – A European Journal, EarlyView.
Mini‐hairpin DNA fragments containing GCGAAGC and GCGAAAGC form exceptionally stable hairpin‐like structures, with only two G−C pairs and one sheared G−A pair, remaining undenatured in 7 M urea and resisting nuclease digestion. These mini‐hairpin sequences frequently appear in replication and transcription origins, influence DNA sequencing fidelity ...

Boron Neutron Capture Therapy at a Crossroads: Translational Gap and Emerging Delivery Agents

open access: yesChemistry – A European Journal, EarlyView.
This review surveys recent advances in boron delivery agents for BNCT, emphasizing the shift from classical small molecules to multifunctional nanocarriers and theranostic systems. By integrating targeting, imaging, and therapy, next‐generation boron compounds aim to bridge the gap between (bio)chemical innovation and clinical translation.

Engineering Lipid Nanoparticles for Precision RNA Delivery: Design Principles, Targeting Strategies, and Clinical Prospects

open access: yesCancer Nexus, EarlyView.
ABSTRACT Lipid nanoparticles (LNPs) represent the most clinically advanced platform for RNA delivery and have enabled major breakthroughs in vaccines and gene therapies. However, their broader application is still limited by inefficient extrahepatic delivery, immunogenicity, and insufficient control over tissue‐ and cell‐specific targeting. This review

Untargeted Metabolomics Identifies N‐Lactoyl‐Amino Acids as Dose‐Responsive Plasma Biomarkers of Metformin Adherence in Type 2 Diabetes

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Metformin is the most widely prescribed antidiabetic drug, yet adherence remains difficult to objectively assess. Using untargeted metabolomics and lipidomics, we analyzed plasma from 637 patients with type 2 diabetes (T2D) with confirmed metformin use and 143 nondiabetic controls, annotating 614 metabolites.

Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline for Thiopurine Dosing Based on TPMT and NUDT15 Genotypes: 2025 Update

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Thiopurine methyltransferase (TPMT) and Nudix hydrolase 15 (NUDT15) are key enzymes that catabolize thiopurines. Decreased or no‐function alleles in TPMT and NUDT15 are associated with reduced or no enzyme activity and predictive of pronounced adverse effects, including severe myelosuppression, that may occur among individuals treated with standard ...
