Hyperchaotic color image encryption using eight-base DNA complementary rules and extended Zigzag transform. [PDF]

PLoS ONE
As an efficient technique to protect image content from unauthorized access, image encryption has been a hot spot in recent studies. Among various schemes of image encryption, those that utilize hyperchaotic systems and deoxyribonucleicacid (DNA ...

Improved nucleic acid sensing, exemplified using pure target DNA sequences, by MO capture probes compared to DNA capture probes, as revealed from PO2−, PO3− and nucleobase mass peaks [PDF]

RSC Advances
Detection of gene mutations is central to molecular diagnostics. The conventional detection methods that employ DNA capture probes are widely used, yet they may suffer from non-specific signals, difficulties in single nucleobase mismatch discrimination ...

Design strategy of antidote sequence for bivalent aptamer: Rapid neutralization of high‐anticoagulant thrombin‐binding bivalent DNA aptamer‐linked M08 with HD22

Research and Practice in Thrombosis and Haemostasis, 2021
Background Bivalent thrombin‐binding aptamers (TBAs) have great potential for the treatment of thrombosis because they exhibit high anticoagulant activity, and their complementary single‐stranded DNA (ssDNA) sequences work as an antidote.
