Paramagnetic particle-based detection system
The use of paramagnetic particles as a label in an immunoassay has resulted in the development of a rapid and highly sensitive biosensing device. Substances in the part-per-trillion concentration range have been measured. The novel instrumentation is inexpensive and can be powered by standard, small batteries to be used as a handheld system for field testing.
A rapid assay system for point of care testing using paramagnetic particles as the label has also been developed and is being evaluated for use for PSA measurement. The assay can be performed on a small blood sample and the result is obtained in a few minutes. The technology has a number of associated patents and collaborative commercialisation opportunities would be welcomed.
