DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity

Small, Volume 22, Issue 43, 3 August 2026.
DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

First‐Time Demonstration of a Two‐Step Mechanism for Azo Dye Removal by Bacillus proteolyticus Using Molecular Docking and FT‐IR

Water Environment Research, Volume 98, Issue 8, August 2026.
Bacillus proteolyticus OA7, isolated from textile wastewater, efficiently removed Acid Red 88 (69.74%) and Acid Blue 193 (41.01%) through substrate‐dependent mechanisms. Acid Red 88 removal involved both biosorption and biodegradation, whereas Acid Blue 193 was mainly biosorbed. FT‐IR revealed functional group changes associated with EPS, proteins, and

Natural variation in OsMYB305 downregulating cytokinin‐mediated inhibition of leaf senescence contributes to regional adaptation in rice

New Phytologist, Volume 251, Issue 4, Page 1873-1888, August 2026.
Proposed regulatory model of OsMYB305 in leaf senescence. Summary Accumulating evidence has identified transcription factors (TFs) as key regulators of the onset and progression of leaf senescence. However, the regulatory role of the rice myeloblastosis (MYB) TF OsMYB305 in this process remains largely unknown.

Performances of p-Aminophenol Redox Cycling by Thiols and Tris(2-carboxyethyl)phosphine on Cysteamine- and 3- Mercaptopropionic acid-Covered Gold Electrodes

International Journal of Electrochemical Science, 2014
Amine- and carboxyl-terminal self-assembled monolayers (SAMs) have been used frequently for controlling the adsorption of biomolecules. p-Aminophenol (p-AP) redox cycling by reducing reagents have been used to improve the sensitivity for signal ...
