Abstract:
Provided herein is a composition for detection of a microbial product in a sample comprising a polydiacetylene (PDA) and a packaging polymer, wherein the sample contacts the PDA and a change of PDA color indicates detection. Also provided herein are methods of making a packaging material comprising a PDA and methods of using the composition for detection of a microbial product in a sample.
Abstract:
In one embodiment, a solution container includes a body adapted to store a solution, a nozzle through which the solution can exit the body, and a biosensor material integrated with the container, wherein the biosensor material has a first color when it has not been exposed to a contaminant but turns a second color when it comes into contact with a contaminant.
