Enhanced through‐bond energy transfer‐based bioorthogonal probe enables catalytic‐amplified and sensitive detection of microRNA‐21 for clinical lung cancer diagnosis

Smart Molecules, EarlyView.
Inverse Diels‐Alder Cycloaddition Reaction was developed for ultrasensitive miR‐21 detection. Based on the enhanced Through‐Bond Energy Transfer and catalytic amplification, it shows a detection limit of 3.58 × 10−18 M and 100 aM–100 nM linear range. It enables high‐contrast cell/tissue imaging and distinguishes lung cancer patients in serum, promising

Optical Control of Therapeutic Synthetic Cells: Controlling Biomolecule Synthesis, Activation, and Communication

Small Methods, EarlyView.
Combining synthetic cells engineering, cell‐free expression, and optical regulation may enable a new generation of programmable synthetic cell platforms. By providing spatiotemporal control over biomolecule synthesis, activation, transport, release, and communication, light offers a versatile strategy for coordinating proteins, RNAs, peptides, and ...

Strategies for enhancing sensitivity in lateral flow assays

VIEW, EarlyView.
Lateral flow assays (LFAs) are essential for cost‐effective, rapid point‐of‐care diagnostics. However, conventional colourimetric LFAs often lack the sensitivity required for low‐abundance biomarkers. This review evaluates six enhancement strategies: flow modulation, sample preconcentration, advanced reporters, chemical signal amplification, structural

Electrochemical aptasensors for ultrasensitive multiplexed detection: Towards a new era of precision diagnostics and environmental monitoring

VIEW, EarlyView.
Electrochemical aptasensors are emerging as powerful platforms for precision diagnostics and environmental monitoring, owing to their high selectivity, programmability and compatibility with miniaturised systems. However, their broader application is constrained by limited signal intensity and challenges in reliable multiplexed detection.

The Functional Role and Molecular Characterization of the Therapeutic Target CLDN6 in Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Background The tight junction protein CLDN6 has been identified as a cancer‐associated cell surface marker that is rarely expressed in healthy tissues. In testicular germ cell tumors (GCT), CLDN6 is particularly detectable in seminomas, embryonal carcinomas, and choriocarcinomas.

Adenosine—A Regulator of Human Testicular Peritubular Cells

Andrology, EarlyView.
ABSTRACT Background Extracellular purines, in particular ATP and adenosine, are regulators of physiological and pathophysiological processes throughout the human body. Roles in the human testis are emerging and include actions on peritubular cells, which form the wall of seminiferous tubules.

Oligodeoxynucleotides Modified with 2'-O-(Cysteinylaminobutyl)carbamoylethylribothymidine Residues for Native Chemical Ligation with Peptide at Internal Positions.

Bioconjugate chemistry, 2022
We used native chemical ligation (NCL) to synthesize a 2'-O-{N-[N-(S-tert-butylthiocysteinyl)aminobutyl]carbamoylethyl} (CysBCE) ribothymidine-derived oligonucleotide to expand the variety of peptide conjugation sites, allowing the incorporation of ...

Oligonucleotide conjugation to a cell-penetrating (TAT) peptide by Diels-Alder cycloaddition.

Organic and biomolecular chemistry, 2008
Modifed oligonucleotides are routinely employed as analytical probes for use in diagnostics, e.g. in the examination of specific RNA sequences for infectious diseases, however, a major limiting factor in oligonucleotide-based diagnostics is poor cellular
