Lectin‐Modified Screen‐Printed Carbon Electrodes (SPE) for the Electrochemical Detection of Transferrin

Electroanalysis, Volume 38, Issue 4, April 2026.
We developed an impedimetric biosensor by electrochemically oxidizing screen‐printed carbon electrodes, allowing the covalent immobilization of Concanavalin A for selective holotransferrin detection. After the target protein is captured, the device monitors changes in charge–transfer resistance using electrochemical impedance spectroscopy.

Effect of nutrient cycle influenced by inter-row cover crops on the nutritional status of rustic grapevine

Revista Facultad Nacional de Agronomía Medellín, 2019
The use of plants for permanent or partial coverage of soil in the vineyard inter-rows is a cultural practice used in various wine-growing regions since it is believed that the decomposition of cover crops’ straw on the soil surface can increase the ...

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.

Bacterial Cellulose Synthase Catalyzes the Formation of Chitin

ChemistrySelect, Volume 11, Issue 15, 20 April 2026.
Recombinant BcsA‐B from Rhodobacter sphaeroides is shown to cleave UDP‐GlcNAc (uridine diphosphate N‐acetylglucosamine), generating chitin with distinct β‐chitin Raman bands. These findings reveal that a cellulose synthase can process an alternative nucleotide sugar, providing biochemical evidence for the co‐synthesis of cellulose and chitin.

Action of Canavalia ensiformis in remediation of contaminated soil with sulfentrazone [PDF]

Bragantia, 2017
ABSTRACT This study evaluated the jack bean (Canavalia ensiformis) as a potential remediator of sulfentrazone in the soil. The experiment was conducted under field conditions in a complete randomised block design. The treatments consisted of soils with and without herbicide application as well as the absence and presence of C.
