Devices, systems and methods for detecting viable infectious agents in a fluid sample using an electrolyte-insulator-semiconductor sensor
First Claim
1. A method for detecting a susceptibility of an infectious agent to an anti-infective, the method comprising:
- introducing a fluid sample to a first surface and a second surface;
exposing the first surface comprising the infectious agent to a. first solution;
exposing the second surface comprising the infectious agent to a second solution, wherein at least one of the second surface and the second solution comprises an anti-infective;
sampling the first solution after exposing the first solution to the first surface;
sampling the second solution after exposing the second solution to the second surface;
monitoring a first electrical characteristic of a first electrolyte-insulator-semiconductor (EIS) sensor exposed to the first solution sampled;
monitoring a second electrical characteristic of a second EIS sensor exposed to the second solution sampled; and
comparing, the first electrical characteristic and the second electrical characteristic to assess the susceptibility of the infectious agent to the anti-infective.

Abstract
Various devices, systems and methods for detecting a susceptibility of an infectious agent to an anti-infective are described herein. A method comprises introducing a fluid sample to a first surface and a second surface; exposing the first surface to a first solution; exposing, the second surface to a second solution, wherein the second surface comprises an anti-infective; sampling the first solution after exposing the first solution to the first surface; sampling the second solution after exposing the second solution to the second surface; monitoring a first electrical characteristic of a first electrolyte-insulator-semiconductor (EIS) sensor exposed to the first solution sampled; monitoring a second electrical characteristic of a second EIS sensor exposed to the second solution sampled; and comparing the first electrical characteristic and the second electrical characteristic to assess the susceptibility of the infectious agent to the anti-infective.
