Screen-printed amperometric biosensors: A balancing act of manufacturing properties, cost efficiency and sensitivity

Detection of Lactate via Amperometric Sensors Modified With Direct Electron Transfer Enzyme Containing PEDOT:PSS and Hydrogel Inks

“…To allow for a widespread use, mobile diagnostic devices suitable for blood lactate detection at the point-of-care are required. Electrochemical sensors [4] are well suited for this purpose, as they combine low production costs such as screen-printing with the possibility of small read out devices. With the trend for non-or minimally invasive diagnostics, also other body fluids are of interest for lactate detection such as interstitial fluid (ISF), which can be accessed via microneedle technology [5][6][7][8].…”
