ChemElectroChem, Volume 13, Issue 9, 5 May 2026.Measuring thrombin activity provides critical information about coagulation health. A voltammetry technique was developed to monitor thrombin activity rapidly on a screen‐printed gold electrode. Thrombin selectively cleaves the bond between para‐nitroaniline (pNA) and a tri‐peptide substrate. pNA cleavage is monitored electrochemically by measuring its

Synthetic oligonucleotides: AFM characterisation and electroanalytical studies [PDF]
, 1967 One of the most important steps in designing more sensitive and stable DNA based biosensors is the immobilisation procedure of the nucleic acid probes on the transducer surface, while maintaining their conformational flexibility.

A Genetic Reporter for Visualizing Nitroreductase Activity Using Magnetic Resonance Imaging
Chemistry–Methods, Volume 6, Issue 5, May 2026.We introduce a reporter gene technology to noninvasively visualize bacterial nitroreductase activity. Our method utilizes a magnetic resonance imaging (MRI) reporter based on aquaporin, which is fused to a destabilizing domain, resulting in their degradation (off‐state).

Repurpose an FDA‐Approved Antibody Using DARPin‐Scaffolded Bridge Protein
Chemistry–Methods, Volume 6, Issue 5, May 2026.The cell line and scalable upstream/downstream process development needed for every new monoclonal antibody are both highly expensive and time‐consuming, significantly increasing the cost of new antibody therapeutics. By contrast, the production of many synthetic binders can be accomplished rapidly and with lower production costs.
