Ultrasensitive disposable apatasensor for reagentless electrocatalytic detection of thrombin: An O2-Dependent hemin-G4-aptamer assay on gold screen-printed electrodes

Lucia Gomez-Arconada et al.

Summary: Serine protease thrombin is a strong neurotoxin and Alzheimer's disease biomarker. In this study, the O-2-dependent aptamer assay for thrombin was adapted to gold screen-printed electrodes (Au SPE) for point-of-care testing (POCT). The assay showed enhanced electrocatalytic activity in O2 reduction upon thrombin binding to the aptamer, and 0.5 fM thrombin was detected with a logarithmic linear range extending to 100 fM. The disposable aptasensor met basic POCT requirements but special surface pre-treatment and modification protocols were needed for practical applications.

Femtomolar Detection of Thrombin in Serum and Cerebrospinal Fluid via Direct Electrocatalysis of Oxygen Reduction by the Covalent G4-Hemin-Aptamer Complex

Kamila Malecka et al.

Summary: Thrombin is a central biomarker in cardiovascular diseases and Alzheimer's disease development, but its electroanalysis is complicated by low physiological concentrations and nonspecific binding. A new electrochemical method was developed to detect femtomolar levels of thrombin in serum and CSF using G4-hemin DNAzyme, which is simple, sensitive, and selective, providing a new tool for ultrasensitive electrocatalytic assays.
