Electrochemical biosensors use electrodes to translate the information received by chemical sensors into electrical signals and are widely used in medical, pharmaceutical, environmental and agricultural applications. This technology can detect small molecules like cholesterol, blood glucose , DNA material, and hemoglobin in blood and urine. By detecting the relevant biomarkers and obtaining a result, treatment is guided. The use of implanted electrochemical biosensors for continuous monitoring of glucose levels or for neurological applications is a constantly developing field.
This type of biosensor differs from liquid chromatography as it is a self-contained device. It can be incorporated into a large analytical system where the sensor can collect information. IST biosensors (https://www.ist-ag.com/en/products-services/bio/biosensors) are designed to accurately measure glucose, lactate, glutamine and glutamate in aqueous media. Enzymatic-amperometric measurement forms the basis of this technology and custom electrochemical biosensors can be built to suit individual applications. Biosensors are also used during food production. The sensor’s accuracy in detecting chemical substances can be used to measure the levels of carbohydrates in different foods, acids and alcohols for good quality control. in the production of beer, yoghurt and cooldrinks.
How does it work?
The sensors are made up of a bio-receptor, a transducer, computer software, and an interface. The bio-receptor binds to the substance, and a chosen biological event is selected using the interface. Next a signal is received and measured by the transducer which converts it to an electronic signal and amplifies it. Software converts this into meaningful information. This data can now be used to indicate further testing, treatments or plan future interventions in the management of medical conditions.
The benefits of using electrochemical biosensors include their cheap production and operational costs and user-friendly interface. They are easy to set up and use and the technology used in their component parts is also fairly durable. The technology used ensures that the sensors are accurate even with small samples. There is no doubt that its many applications have made the electrochemical biosensor indispensable in many fields and that our lives have been made richer by its existence. Human health has been substantially enhanced by using this technology in the fields of biochemistry and laboratory analysis.
