Abstract
The present disclosure relates to devices and methods for detecting glyphosate. More specifically, the present disclosure relates to a device comprising a fluorescently labeled glyphosate binding protein as a biosensor that is configured to change fluorescence as a function of glyphosate concentration, a first excitation source operable to excite the biosensor at a first wavelength, a light detector configured to collect emitted light, and a processor configured to process any difference in fluorescence before and after a sample is added to the biosensor.
Claims18
A device for detecting glyphosate in a sample, comprising:
- a fluorescently labeled glyphosate binding protein as a biosensor element,
- a first excitation source operable to excite the biosensor element at a first wavelength,
- a light detector configured to collect emitted light, and
- a processor configured to process any difference in fluorescence before and after a sample is added to the biosensor element.
A method for detecting glyphosate, comprising:
- adding a sample to a portable device comprising a fluorescently labeled glyphosate binding protein,
- exciting the protein with an appropriate wavelength,
- collecting emitted light from the protein through a light detector,
- processing the collected light to determine any difference in fluorescence before and after a sample is added, and
- providing a binary result indicating the presence or absence of glyphosate.
