Dissipatively Fueled Unidirectionally Communicating DNA Circuits That Control Biocatalysis
Unidirectionally communicating, out‐of‐equilibrium DNA circuits are used to control enzyme activity. Transient DNAzyme activation generates fuel for temporal trypsin activation. Cyclic fuel‐driven hybridization and exonuclease‐mediated reset enable precise control over lifetimes, which is analyzed using combined experimental and computational ...

Visualizing and Quantifying microRNA‐Induced DNA Origami Separation at the Nanoscale
Clinically relevant miRNA biomarkers trigger the disassembly of DNA origami dimers into monomers through a toehold‐mediated strand displacement reaction. High‐speed AFM was used to visualize this reaction in real time, while solid‐state nanopore measurements quantified the populations of dimers and monomers, as well as the resulting miRNA concentration,

This study introduces an affordable machine learning platform for simultaneous dengue and zika detection using fluorine‐doped tin oxide thin films modified with gold nanoparticles and DNA aptamers. Designed for low‐cost, hardware‐limited devices (< $25), the model achieves 95.3% accuracy and uses only 9.4 kB of RAM, demonstrating viability for resource‐

Aptamers are single strand DNA or RNA molecules, selected by an iterative process known as Systematic Evolution of Ligands by Exponential Enrichment (SELEX). Due to various advantages of aptamers such as high temperature stability, animal free, cost effective production and its high affinity and selectivity for its target make them attractive ...

Mucin Glycoprotein Nanoparticles Enable a Selective Antisense Therapy for Oncogenic MicroRNAs
Mucin glycoproteins are turned into nanoparticles by employing synthetic DNA strands, which have a dual function: they stabilize the nanoparticles and act as binding sites for intracellular miRNA‐21. Thus, upon internalization into tumor cells, these mucin nanoparticles can deplete miRNA‐21 from the cytosol, which induces apoptosis in vitro and in vivo.

Detection of low‐abundance proteins at the point‐of‐care is key for early detection and real‐time monitoring. The clinical translation of such assays is hindered by biofouling, matrix variability, and signal instability. RT‐MagMAp assay overcomes these challenges and enables precise protein quantification in human plasma using a hierarchical assembly ...
