Acinetobacter Baumannii Detection Using A Bio-FET Device: Towards Healthcare Infection Management

Acinetobacter is a group of bacteria commonly found in the environment, like in soil and water. While there are many types, the most common cause of infections is Acinetobacter baumannii, which accounts for most Acinetobacter infections in humans. Acinetobacter baumannii could result in infections in the blood, urinary tract, in wounds of the body or lungs. Traditionally, medical technicians in hospital use the sample from patients (like stool, urine, or sputum) to streak on a plate or do bacteria culture test. It takes too much time and patients cannot wait so long. Therefore, it is vital that a new diagnostic technique can be used to detect Acinetobacter baumannii much faster than the traditional methods. The electrical double layer (EDL)-gated field-effect transistor-based biosensor (BioFET) is a fast and promising diagnostic technique because it is highly sensitive, quickly response, and high selective to the target analyte. Besides, a portable device could help the medical personnel detect the bacteria and treat the patients as early as possible. Here, we used a portable BioFET device from STARX co. (Model II) to detect the complementary Deoxyribonucleic acid (DNA) of Acinetobacter Baumannii via a specific DNA probe we designed. We utilized the portable device to examine the specificity and selectivity in various conditions, such as urine and blood. Thus, the results showed that the system with the portable device could give the hospital personnel a tool to control healthcare associated infection caused by Acinetobacter baumannii . Figure 1
