Tuning of the Optical Properties of Cis‐ and Trans‐Bis‐Tetrazo[1,2‐b]indazoles Guided by Predictive DFT: An Isomer Story

Advanced Optical Materials, Volume 14, Issue 16, 24 April 2026.
We report the synthesis and properties of novel N‐rich polyaromatics (cis‐ and trans tetrazo[1,2‐b]indazoles). Following a density functinal theory (DFT)‐guided molecular engineering, we introduced substituents at various positions. The effect of these substituents on the spectroscopic/redox properties was fully rationalized by DFT.

High‐Throughput Glucose Biosensing Using Jack Bean [Canavalia ensiformis (L.) DC.] Lectin as Electrochemical Signaling Element

Electroanalysis, Volume 38, Issue 4, April 2026.
An electrochemical biosensor employing Canavalia ensiformis lectin immobilized on a Prussian Blue‐modified glassy carbon electrode was developed for label‐free glucose detection at submicromolar levels. The integration of lectin biorecognition with the conductive Prussian Blue layer ensured stable and selective signal transduction.
