Summary

A major focus of Seafood CRC funded project (2011/726: Wanted Dead or Alive - Novel Technologies for Measuring Infectious Norovirus Particles) is the development of sensitive biosensors for the detection and discrimination of infective human norovirus (NoV). A critical step in achieving this is the biological functionalisation of the sensor platform.

Dr Torok spent two weeks during 2014 in the laboratory of Dr Maria DeRosa undertaking experiments to generate specific bioreceptors (aptamers) for human norovirus (NoV). The De Rosa Laboratory is actively involved in the development of biosensors and ‘smart’ materials based on DNA aptamers. Aptamers are single-stranded oligonucleotides that fold into distinct three-dimensional conformations, capable of binding strongly and selectively to a target molecule and have several advantages over antibody based approaches. The DeRosa group is developing aptamers to various targets including neurotransmitters, viruses, disease biomarkers and toxins, as well as utilising these in the development of electrochemical and optical biosensors.
