Abstract
Embodiments of the present Invention provide antibody functionalized high electron mobility transistor (HEMT) devices for marine or freshwater pathogen sensing. In one embodiment, the marine pathogen can be Perkinsus marinus. A sensing unit can include a wireless transmitter fabricated on the HEMT. The sensing unit allows testing in areas without direct access to electrical outlets and can send the testing results to a central location using the wireless transmitter. According to embodiments, results of testing can be achieved within seconds.
Claims20
A marine or freshwater pathogen detection system, comprising:
- a marine or freshwater pathogen sensor comprising a high electron mobility transistor (HEMT) on a substrate and at least one capture reagent for a marine or freshwater pathogen on a gate region of the HEMT;
- and
- a wireless transmitter on the substrate and connected to the HEMT for transmitting an output of the marine or freshwater pathogen sensor from a testing location to a receiving location.
A method of detecting a marine or freshwater pathogen, comprising:
- contacting a gate region of a high electron mobility transistor (HEMT) marine or freshwater pathogen sensor with water being tested;
- and
- monitoring drain current of the HEMT marine or freshwater pathogen sensor to determine presence of marine or freshwater pathogens, wherein a change in drain current occurs upon exposure of the HEMT marine or freshwater pathogen sensor to marine or freshwater pathogen-infected water;
