Dual‐Channel Interdigitated Aptamer‐Based Sensors for Rapid Small‐Molecule Detection in Biofluids

Angewandte Chemie International Edition, EarlyView.
An electrochemical aptamer sensing chip employs dual interdigitated electrodes and selective self‐assembled monolayer removal to convert small‐molecule recognition into robust “signal‐off/on” responses. This dual‐channel signal conversion minimizes background noise and accelerates probe diffusion, enabling rapid (as fast as 5–30 min), low‐volume ...

Sensitive detection systems for infectious agents in xenotransplantation*

Xenotransplantation, EarlyView., 2020
Abstract Xenotransplantation of pig cells, tissues, or organs may be associated with transmission of porcine microorganisms, first of all of viruses, to the transplant recipient, potentially inducing a disease (zoonosis). I would like to define detection systems as the complex of sample generation, sample preparation, sample origin, time of sampling ...

Dynamics of Heparin Translocations Through Solid‐State Nanopores

ELECTROPHORESIS, EarlyView.
Carbohydrates can be detected with solid‐state nanopores, but their kinetics of voltage‐driven passage are fast. To better understand the dynamics of passage of these biomolecules and the role of electrophoresis and electroosmosis, we studied the translocation characteristics of heparin as a function of salt concentration, pH and voltage polarity ...

A dendrimer enhanced CRISPR/Cas12a performance for the evaluation of acidogenic capacity in cariogenic bacteria

Interdisciplinary Medicine, EarlyView.
A CRISPR/Cas12a‐powered dendritic DNA nanostructure is assembled to create confined enzymatic microdomains, enabling ultrasensitive detection. Integrated into a paper‐based origami biosensor, it allows equipment‐free on‐site quantification of acidogenic pathogens for the early diagnosis of dental caries.

Proof of ssDNA degraded from dsDNA for ET recombination

Biochemistry and Biophysics Reports
The widely used ET recombination requires an ssDNA product degraded by Rac phage protein E588 from dsDNA for strand invasion. However, proof of the ssDNA product is still elusive. The study provided three levels of proof sequentially. The probable ssDNAs

Ordered assembly of Cas12a for better performance of CRISPR/Cas system with application to the diagnosis of dental caries

Interdisciplinary Medicine, EarlyView.
Here, we present a tetrahedral DNA framework (TDF)‐mediated Cas12a ordered assembly strategy. TDFs arrange CRISPR/Cas12a into ordered structures controllably, enhancing catalytic efficiency through localized Cas12a hotspots while maintaining spatial intervals to facilitate substrate diffusion.
