Directed Synthesis of Humic and Fulvic Derivatives with Enhanced Antioxidant Properties

open access: yesAgronomy, 2021
Redox moieties, which are present in the molecular backbone of humic substances (HS), govern their antioxidant properties. We hypothesized that a directed modification of the humic backbone via incorporation of redox moieties with known redox properties ...

A Portable Colorimetric Device for Rapid Bacterial Detection with Cleavable Functional Nucleic Acid Probes for A Common Bacterial Endoribonuclease

open access: yesAngewandte Chemie, EarlyView.
A simple, rapid, and portable gold‐coated filter tip‐based assay (GFTA) is developed for bacterial detection. The GFTA leverages cleavable functional nucleic acid probes as molecular recognition elements to target RNase H2, a highly conserved bacterial endoribonuclease, enabling sensitive and specific colorimetric detection of bacterial pathogens ...
