Determinación de cinética de crecimiento de Pseudomona Aeruginosa por mediciones de impedancia eléctrica

Abstract

Impedance spectroscopy is a technique for characterising electrochemical systems. The fundamental approach of all impedance methods is to apply a small-amplitude sinusoidal excitation signal to the system under investigation and measure the response, which may be current, voltage or other signal of interest. This non-invasive method, together with the ‘lab on a chip’ technology of microelectronic devices, makes it possible to study microelectronic devices, makes it possible to study microscopic systems, requiring only a small amount of sample. For the development of the the fabrication of microelectronic devices and their implementation to determine the growth kinetics of the bacterium Pseudomonas pneumoniae. growth kinetics of Pseudomonas aeruginosa bacteria in BHI (Brain Heart Infusion) culture broth. The interest in this particular species of The interest in this particular species of bacteria lies in the fact that it is considered to be the most frequent cause of nosocomial, respiratory and urinary infections worldwide, being able to develop resistance mechanisms that make it immune to antimicrobial drugs. This effort was made possible thanks to the interdisciplinary collaboration of the Thin Films and Nanotechnology research groups at the Pontificia Universidad Javeriana and the Materials and Minerals and Materials and Minerals and High Mountain Biodiversity research groups of the Universidad Distrital.
