Stimuli‐Responsive DNA Circuits for High‐Performance Bioimaging Application
Advanced Sensor Research, Volume 2, Issue 9, September, 2023., 2023 The development of DNA circuits that respond to external physical stimuli (light, magnetic fields, and ultrasound) and internal biological stimuli (pH, enzymes, nucleic acids, redox, and small molecules) is summarized. These stimuli‐responsive DNA circuits enable spatiotemporally controlled bioimaging with high performance.

Statistical study of extreme-ultraviolet nanoflares in the quiet-Sun transition region
Astronomy & Astrophysics, 2023 Aims. We carried out a large statistical study of ubiquitous small-scale extreme-ultraviolet (EUV) brightenings in the nanoflare energy range in the quiet-Sun transition region to derive their properties, estimate their contribution to the heating of the ...

Advanced Materials, Volume 35, Issue 34, August 24, 2023., 2023 Rapid development of plasmonics leads to the evolvement of metal nanostructures capable of dramatic enhancement of fluorophore emission. For fluorescence‐based biosensors, plasmonic nanomaterials may enable improved detection sensitivity or use of low‐cost detectors for point‐of‐care testing.

Signatures of Type III Solar Radio Bursts from Nanoflares: Modeling [PDF]
Astrophysical Journal, 2021 There is a wide consensus that the ubiquitous presence of magnetic reconnection events and the associated impulsive heating (nanoflares) are strong candidates for solving the solar coronal heating problem.

Chondroitin Sulfate-Coated Heteroduplex-Molecular Spherical Nucleic Acids. [PDF]
Chembiochem[60]fullerene‐based molecular spherical nucleic acids (MSNAs) were used as hybridization‐mediated carriers for an antisense oligonucleotide, suppressing Tau protein, and its conjugates with chondroitin sulfate (CS) tetrasaccharides. The impact of the MSNA‐carriers and the CS‐halo on the cellular uptake and suppression of Tau‐protein was studied with ...

Plasma‐activated liquids for mitigating biofilms on food and food contact surfaces
Comprehensive Reviews in Food Science and Food Safety, Volume 22, Issue 3, Page 1654-1685, May 2023., 2023 Abstract Plasma‐activated liquids (PALs) are emerging and promising alternatives to traditional decontamination technologies and have evolved as a new technology for applications in food, agriculture, and medicine. Contamination caused by foodborne pathogens and their biofilms has posed challenges and concerns to the food industry in terms of safety ...
