New Generation of GaN-based sensor arrays for nano- and pico-fluidic systems for fast and reliable biomedical testing (GANANO) - Publishable Final Activity Report

Project ID: 505641
Funded under: FP6-NMP

Abstract

Hospitals and medical laboratories have to analyze thousands of tiny samples on a daily basis. This is ideally carried out quickly, efficiency and with a high degree of sensitivity, enabling early detection of conditions such as AIDS, Creutzfeldt - Jakob disease and cancer. Rapid diagnosis can save lives, improve a patient's quality of life and also reduce medical treatment costs.
GaNano is three-year EUR 2.3 million EU-project coordinated by the Technical University Ilmenau with eight other European partners to construct the first instrument based on GaN devices to address this need. GaN and its related alloys are well-suited to this task, and unlike the GaAs and InP families they can form the basis chemical sensors that are not degraded by various samples, including those that are acidic and alkaline. The following results and deliverables are achieved by the members of the consortium and the effect of an excellent cooperation.
These sensors, which are the key part of the instrument, analyze the chemical properties of nanolitre and picolitre samples that are brought into contact with the device's surface. The devices - essentially transistors with an eliminated top gate or a modified active gate area - can detect dipoles, polar liquids, changes in ion concentration, and cell activity, because this alters the device's surface potential and leads to a change in current flowing through the underlying two-dimensional electron gas (2DEG).
