Near‐infrared light‐activated aptamer‐based nanoprobe for spatiotemporally resolved detection of L‐lactate in colorectal cancer

BMEMat, EarlyView.
A near‐infrared (NIR) light‐activated “lock‐key” nanodevice is reported for spatiotemporally resolved detection of intratumoral L‐lactate. The system stays silent until deep‐penetrating NIR light remotely unlocks its function, allowing for precise sensing within tumors.

From pathogen to “living drug factory” innovative strategies and clinical translation of bacteria as programmable intelligent vectors for cancer therapy

BMEMat, EarlyView.
Engineered bacteria serve as smart, living therapeutics that target tumors, deliver drugs, and remodel immunosuppressive microenvironments. This review highlights their potential to potentiate immunotherapy, radiotherapy, and chemotherapy, offering a promising paradigm for precise and synergistic cancer treatment. Abstract The dynamic interplay between

Inclusion Complexations of Levamisole and Cocaine With Molecular Baskets. Fluorescence Displacement Assay for Detection of Cocaine and Its Adulterant Levamisole in Aqueous Media

Chemistry – A European Journal, EarlyView.
Levamisole is a common adulterant found in street‐distributed cocaine. Molecular baskets have been shown to form stable inclusion complexes with both substances. While levamisole inserts its benzene into the basket's cavity, cocaine utilizes its bicyclic ring for encapsulation.

An Electrophilic Uridine Building Block for Post‐Synthetic RNA Modification as Exemplified for Spin Labeling

Chemistry – A European Journal, EarlyView.
An electrophilic 5‐isothiocyanatomethyl uridine building block enables modular post‐synthetic RNA labeling with primary amine‐containing probes. Positioning the functionality in the major groove minimizes structural perturbation and allows facile conjugation of sensitive tags such as TEMPO spin labels for paramagnetic relaxation enhancement studies ...

Introduction of a Double‐Headed Nucleotide Into G‐Quadruplex DNA: Position‐Dependent Stabilization and Structural Insights

Chemistry – A European Journal, EarlyView.
A double‐headed bis‐guanine (G) nucleotide (GG) was evaluated as a noncanonical building block in G‐quadruplexes (G4s). Biophysical and computational analyses reveal that GG can directly participate in G‐tetrads and strongly stabilize G4s in a position‐ and topology‐dependent manner. These findings establish design rules for using GG to engineer highly

4′‐ThioRNA Substitution and Sense‐Strand Segmentation for the Design of Functional Fully Modified siRNAs Targeting SARS‐CoV‐2

Chemistry – A European Journal, EarlyView.
4′‐ThioRNA was broadly tolerated across multiple positions in SARS‐CoV‐2‐targeting siRNAs, but full 4'‐thio modification of both strands caused a reduction in RNAi activity. Sense‐strand segmentation improved RNAi and antiviral activity, particularly when the nick was located at position 10 from the 5′‐end of the sense strand, thereby unlocking the ...

Multivalent RNA‐Cleaving Agents on a Cubic Octameric Silsesquioxane Core

Chemistry – A European Journal, EarlyView.
RNA‐cleaving agents on a cubic octameric silsesquioxane core were synthesized and characterized. Several catalytic systems of these structures were screened using hexaribonucleotide models. The best systems were then further used to study their catalytic efficiency in cleaving a HER2 mRNA model sequence. The induced cleavage sites were also determined.

Nano MIPs (Molecularly Imprinted Polymers) Prepared From a “Frustrated” Gold Nanoparticle‐Based Pre‐Imprinting Matrix: Enhancing Binding Affinity and Selectivity

Chemistry – A European Journal, EarlyView.
A comparative study across ligand‐stabilized gold nanoparticles and surfactant micelles reveals that molecular imprinting strongly depends on the nanoplatform used for imprinting. “Frustrated” noncovalent interactions within the monolayer on gold nanoparticle surface can be exploited to improve both the binding affinity and selectivity for ...
