DNA Origami‐Templated Aptamer Chiral Structures Realize Cellular Enantioselectivity
Advanced Materials, EarlyView.Aptamers displayed on tubular DNA origami nanostructures in defined chiral orientations (left‐ or right‐handed) exhibit enantioselective interactions with cell surface target proteins. While the right‐handed configuration supports only transient binding, the left handedness energetically favors protein dimerization and promotes subsequent ...

Cellulose‐Nanofiber‐Based Layered Sub‐Terahertz Absorbing Sheets for B5G/6G Applications
Advanced Materials Technologies, EarlyView.We report a sub‐terahertz absorber made of biodegradable cellulose‐nanofiber (CNF), potentially useful for B5G/6G devices to achieve electromagnetic compatibility in an eco‐friendly way. The absorber is 120 µm thick and consists of two carbon‐nanotube‐dispersed CNF layers and one pure CNF layer.

PCV2 infection aggravates OTA-induced immunotoxicity in vivo and in vitro
Ecotoxicology and Environmental Safety, 2022 Ochratoxin A (OTA), frequently existing in the food and feeds, could induce immunotoxicity. Porcine circovirus type 2 (PCV2), as a primary causative agent of porcine circovirus–associated disease, also could induce immunosuppression. However, it is still

Mechanistic Origin of Photodegradation and Impurity Effects in Donor–Acceptor Luminescent Radicals
Advanced Optical Materials, EarlyView.Purification‐dependent impurities distort the apparent optical and analytical data of TTM‐based radicals without altering their intrinsic photophysical properties. Carbazole attachment elevates the activation barrier of the photodegradation pathway, offering design principles for achieving more robust luminescent radical materials.

Isolation, Screening and Identification of Swine Gut Microbiota with Ochratoxin A Biodegradation Ability [PDF]
Asian-Australasian Journal of Animal Sciences, 2012 The potential for ochratoxin A (OTA) degradation by swine intestinal microbiota was assessed in the current study. Intestinal content that was collected aseptically from swine was spiked with 100 ppb OTA and incubated for 6 and 12 h at 39°C. An OTA assay
