Description

Sensing device and antibiotic susceptibility diagnosis method using the same The present invention relates to a sensing device and a method for diagnosing antibiotic susceptibility using the same, and more specifically, to a sensing device using a sensor and an electrode and a method for diagnosing antibiotic susceptibility using the same. Among the various diseases that occur in the human body, there are those caused by microbial infections, including urinary tract infections and sepsis. To treat diseases caused by such microbial infections, antibiotics are required to inhibit the proliferation of microorganisms, and antibiotics either suppress the growth of microorganisms or kill them. However, more than 100 types of antibiotics have been developed to date, and their effectiveness varies depending on the type of microorganism or whether it is resistant to antibiotics. Therefore, the most effective antibiotic must be selected for each patient, and the diagnostic test method for this purpose is called antibiotic susceptibility testing. For such antibiotic susceptibility testing, the structure is designed to test antibiotic susceptibility through a sensor within a space containing a fluid that includes antibiotics and microorganisms. Korean Registered Patent Publication No. 10-2570520 discloses a biosensor using a PET substrate, a method for manufacturing the same, and a method for testing the antibiotic susceptibility of microorganisms using the same. However, in such antibiotic susceptibility diagnostic methods, there are cases where electrical signals are not transmitted properly due to the formation of bubbles in the space containing the fluid containing antibiotics and microorganisms. Therefore, there is an urgent need to develop technology that prevents bubble formation in the space containing the fluid containing antibiotics and microorganisms for antibiotic susceptibility testing, thereby enabling the effective transmission of electrical signals.
