A catalase-based (NAF/MWCNTs) nanocomposite film modified glassy carbon electrode for hydrogen peroxide (H2O2) detection was developed. The developed biosensor was characterized in terms of its bioelectrochemical properties. Cyclic voltammetry (CV) technique was employed to study the redox features of the enzyme in the absence and in the presence of nanomaterials dispersed in Nafion® polymeric ...
BACKGROUND When using a reduced ECG lead system with three leads or less, the analysis of atrial activity during arrhythmias can become problematic due to low signal amplitude and noise. Long ago, Sir Thomas Lewis proposed a lead system for atrial activity enhancement in which two electrodes are placed directly on the chest, however, these leads are sensitive to arm movement artifacts. In this ...
