Wireless based marine pathogens detection system

摘要

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.

主权项

1. 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; 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; and a waterproof packaging encapsulating the marine or freshwater sensor and the wireless transmitter, wherein the HEMT is configured such that a change in drain current while a constant drain bias is applied and the gate region is contacted with water being tested indicates that a marine or freshwater pathogen is present in the water being tested, and wherein the marine or freshwater pathogen detection system generates a visual output or an audio output indicating detection of pathogens at the testing location.
