Recent Advances in Disposable Electrochemical Sensors

Disposable sensors are becoming increasingly used in the healthcare industry for quick and affordable biomarker screening and monitoring. The electrochemical detection technique makes it simple to scale up and miniaturize inexpensive disposable sensors, can be employed for accurate biomarker measurement at or close to the patient site. The paper-based analytic tools make it easier to sample in situ, search for biomarkers, and detect them multiplexedly. This chapter describes the high-throughput fabrication methods used to create disposable electrodes, such as paper based electrodes, screen-printing, ink jet printing, and laser induced printing, and goes into detail on how they can be utilized for various enzymatic, nonenzymatic, and aptamer-based sensing. The effectiveness of nanostructured materials in enhancing electrochemical sensor performance is outlined. Additionally, current innovations in hybrid wearable devices capable of sensing various analytes.
