Researchers from Manchester developed miniaturized electric sensor for heart attack

A research group at Manchester, together with a team at India’s Institute of Nano Science and Technology (INST), has developed a nanoscale electric sensor for heart attack detection.

The miniaturized sensor is made from a new 2-dimentional material ‘few-layer black phosphorus’ which is immobilized with DNA molecules. When heart attacks occur, certain chemicals such as myoglobin will be released into bloodstream and the elevated level of these chemicals can be used for the diagnosis of heart attack. The DNA molecules immobilized on black phosphorus can bind to myoglobin and therefore a simple electrical test could be realized based on this.

This new sensing method is potentially a rapid, accurate, sensitive and selective approach for the detection of heart attack. It is also predicted that eventual introduction of this method into clinic will improve patient survival rates after a heart attack.

This is the first report of biological sensing development using the new 2-dimentional material few-layer black phosphorus.
