What triggers the release of the nanoparticle in the S.aureus protease biosensor?
Understand the Problem
The question is asking about the specific mechanism that initiates the release of nanoparticles in a biosensor designed for detecting S. aureus protease. It looks for the underlying trigger among the provided options.
Answer
The addition of S. aureus protease solution triggers nanoparticle release.
The release of the nanoparticle in the S. aureus protease biosensor is triggered by the addition of the S. aureus protease solution on the electrode surface, which causes cleavage of the peptide sequence.
Answer for screen readers
The release of the nanoparticle in the S. aureus protease biosensor is triggered by the addition of the S. aureus protease solution on the electrode surface, which causes cleavage of the peptide sequence.
More Information
The cleavage of the peptide sequence by S. aureus protease solution causes the release of magnetic nanoparticles. This release can be visually detected as it reveals the golden color of the electrode, making it observable with the naked eye.
