Abstract
Recent advances in the electrochemical biosensors is increasing the popularity of the point of care devices since the electrochemical sensor can provide low cost, portability, detectability, experimental simplicity, and capacity to provide real time monitoring. The point of care devices has been used in various biomedical applications such as blood glucose monitors, pregnancy tests, HIV tests, hemoglobin level tests etc. However, the existing portable devices are limited to a specific sensing mechanism due to the inability to include the various electrochemical sensing techniques into a compact formfactor. Thus, there is a need for miniaturized all-in-one electrochemical sensing platform for the point of care devices. In this research, we present a portable electrochemical sensing platform designed and implemented from hardware to software for the point-of-care device to accommodate widely used electrochemical sensing mechanism including amperometry, voltammetry. To control the systems interfacing with the smart-devices and computers as well as displaying the obtained data, an android application and a graphical user interface were developed in open-source programming using commercial-off-shelf components which consists of a microcontroller unit with readout circuit, a multiplexer, and wired communication unit. The proposed electrochemical sensing platform accommodates electrochemical techniques such as linear sweep voltammetry, cyclic voltammetry, amperometry, anode strip voltammetry, chrono amperometry and square wave voltammetry. We performed experiments on proposed system. The Potentiostat dummy cell array tests was performed for the aqueous phase detection and test results showed the linear response, which is important in electrochemical sensing system.
