Understanding the Catalytic Determinant role of Diaphorase‐Like Subunit in Formate Dehydrogenases via Redox Couples

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A unique mechanism of catalytic bias regulated by diaphorase‐like subunit in formate dehydrogenase from Rhodobacter aestuarii is revealed. The diaphorase‐like subunit functions act as a biological “voltage rheostat” that controls the slow release of NADH to regulate redox balance, biasing the enzyme's catalytic preference toward CO2 reduction over ...

An Advanced Molecularly Imprinted Polymer‐Based Electrochemical Aptasensor for Carbendazim Detection

Advanced Materials Interfaces, Volume 13, Issue 12, 23 June 2026.
A dual‐recognition electrochemical aptasensor that integrates a molecular imprinted polymer (MIP) and an aptamer is developed for the detection of a common pesticide, carbendazim (CBZ). The resulting sensor exhibits enhanced selectivity toward CBZ over structurally similar compounds and achieves a low detection limit of 1.3 nm, demonstrating its ...
