Design of a bio-Sensor-based portable and rapid poison detection device. Case study: Organophosphates poison

Abstract

Organophosphates are a class of chemicals that are used in a variety of products, including insecticides, herbicides, and pesticides. They are also used in some chemical warfare agents. Potential sources of organophosphate poisoning include occupational exposure such as agricultural workers, pesticide applicators, and other workers who handle organophosphates are at risk of occupational exposure. Accidental exposure is another source of organophosphate that can be accidentally ingested, inhaled, or absorbed through the skin. Suicide or homicide are also sources of organophosphates which are used in suicide attempts or homicides. This work describes the design of a bio-sensor-based portable and rapid poison detection device specifically organophosphate poison which is an exciting technology that has the potential to revolutionize the way we detect these dangerous chemicals. This device is potable, lightweight, and easy to use, making it ideal for use in medical diagnostics application settings. The methodology used to develop this device includes the proteus professional software tool which is used to interconnect circuit components and simulation of the designed device. Also, another software tool used to accomplish this project is Atmel studio version 6.2 which generates codes for the microcontroller (Arduino-uno) operations, whereby these codes make easily for Arduinouno to receive bio-signals from bio-sensors then process them by converting them into equivalent electrical signals and finally displaced as output by using Liquid crystal display (LCD). The key findings of this project are the rapid detection of organophosphate poison, portability sensitivity, and selectivity. The device can detect organophosphate poison within ten (10) seconds compared to other existing organophosphate poison devices which took almost an hour. The significance of this device is that it is small, lightweight, easy to use, and rapid detection. Further research needs to be done to improve this design by integrating the device with the Internet of Things (IoT) which helps the results to be accessed by using smart devices owned by medical doctors. This technology will improve the provision of health services, especially during the interpretation of the results of poison detected.
