Monitoring of metabolic compounds, such as glucose and lactate, is extensively reported in literature, especially for clinical purposes. Instead, the application of such technologies for monitoring metabolites in cell cultures has not been explored. From one side, such devices can provide information to the current state-of-the-art of cell lines, particularly those which are not fully known, as stem...
Nano-biosensing provides new tools to investigate cellular differentiation and proliferation. Upon the various metabolic compounds secreted by cells during life cycles, glucose, lactate and hydrogen peroxide (H2O2) are of first interest. Nanostructured electrodes may enhance the compounds sensitivity in order to precisely detect cell cycle variation. In the present paper, the detection with electrodes...
A novel disposable lactate biosensor was reported, which can measure the lactate in whole blood and other bio-fluids rapidly, accurately, expediently and directly. The biosensor was based on two kinds of electron mediator, the ferricyanide and the modified carbon nanotubes (CNT). Lactate oxidase (LOD) was coated on the electrodes. The sensor was fabricated by screen-printed techniques, the sample...
