Design and Characterization of DX‐Tile DNA Nanostar‐Based Hydrogels

Advanced Science, EarlyView.
In this study, the authors demonstrated that DNA DX‐tile‐based multi‐arm motifs can be used to assemble pure DNA hydrogels, offering greater design flexibility and enhanced control over their mechanical properties and functionalization capabilities compared to single duplex‐based DNA hydrogels.

cDC1 Subtype‐Specific In Vivo Targeting of Liposomes

Advanced Science, EarlyView.
Dendritic cells, particularly the cDC1 subtype, offer a promising target for drug delivery via liposomes due to their pivotal role in immune regulation, allowing for amplified therapeutic responses. Herein, we show an integration of physicochemical characterization and cell experiments to achieve effective in vivo cDC1 targeting through anti‐CLEC9A ...

Aptamer-based field-effect transistor for detection of avian influenza virus in chicken serum.

Analytical Chemistry, 2020
Early diagnosis of the highly pathogenic H5N1 avian influenza virus (AIV) is significant for preventing and controlling a global pandemic. However, there is no existing electrical biosensor for detecting biomarkers for AIV in clinically relevant samples ...

Spatiotemporal Organization of PTK7 Diffusion on Cell Surface Facilitates Tumor Invasion and Migration

Advanced Science, EarlyView.
The spatiotemporal dynamics of protein kinase diffusion govern cellular signaling and functions. Although vital for active receptors, the role of pseudokinase dynamics is unclear. Here, we use single‐molecule tracking to link faster diffusion of pseudokinase PTK7 to increased tumor cell invasion and migration.

Interactions of Ligand, Aptamer, and Complementary Oligonucleotide: Studying Impacts of Na⁺ and Mg²⁺ Cations on Sensitive FRET-Based Detection of Aflatoxin B1

Molecules
The effects of magnesium and sodium on the interactions between aptamer, its specific ligand, and short complementary oligonucleotides (cDNAs) differing in affinity of their binding with the aptamer were studied.

A Modular DNAzyme for Precise Visualization and Intervention of Alternative Splicing Isoforms in Live Cells

Advanced Science, EarlyView.
A Stringent dUPlex‐activated Error Robust (SUPER) DNAzyme system enables real‐time imaging of alternative mRNA splicing (e.g., Bcl‐xL/Bcl‐xS) in living cells via target‐triggered split‐DNAzyme reassembly and dual‐color fluorescence. It also achieves mRNA‐selective knockdown through DNAzyme‐based gene regulation, serving as a versatile tool for splicing

Control of Aptamer Function Using Radiofrequency Magnetic Field

Journal of Nucleic Acids, 2011
Remote control of aptamer function has allowed us to control protein function in space and time. Here, we propose a novel control system for aptamer function by radiofrequency magnetic field- (RFMF-) induced local heating of a gold nanoparticle ...

Dynamic Decoration of DNA Scaffolds for High‐Resolution Cancer Cell Subtyping

Advanced Science, EarlyView.
This study presents a dual‐mode imaging platform that utilizes self‐assembly and disassembly of DNA scaffolds for high‐resolution cancer cell detection. The structural rigidity of DNA scaffolds effectively prevents cellular internalization for over 300 min.
