About the Presenter

Scientia Professor Justin Gooding

Scientia Professor Justin Gooding graduated with a B.Sc. (Hons) from Melbourne University before spending two years working for ICI Research. He then returned to University obtaining a D.Phil. from the University of Oxford and received post-doctoral training at the Institute of Biotechnology in Cambridge University.

He returned to Australia in 1997 as a Vice-Chancellor's Post-Doctoral Research Fellow at the University of New South Wales (UNSW) before commencing a lectureship at Flinders University in 1998 and then UNSW in 1999. He was promoted to full professor in 2006 and in 2011 he was promoted to Scientia Professor, the highest award for research performance given by UNSW. He is currently co-director of the Australian Centre for NanoMedicine.

He was one of the recipients of a 2004 NSW Young Tall Poppy award, a 2005 Alexander von Humboldt Fellowship, the 2007 RACI Lloyd Smythe Medal for Analytical Chemistry, the 2009 Eureka Prize for Scientific Research, the 2011 RACI H.G. Smith Medal, the 2011 RACI R.S. Stokes Medal and the 2012 RSC Australasian Lectureship.

He is currently and ARC Professorial Fellow in the School of Chemistry at UNSW where he leads a research team of 23 people interested in surface modification and nanotechnology for biosensors, biomaterials, electron transfer and medical applications.

Our research group works at the boundaries of analytical chemistry, physical chemistry and biochemistry. We specialise in nanostructuring surfaces to provide them with unique functionality. Most frequently we use self-assembled monolayers for modifying the surfaces but also use nanomaterials, such as carbon nanotubes and nanoparticles, and polymers.

A large part of this program is the development of biosensors. Biosensors exploit biological recognition molecules, such as enzymes, peptides and DNA, for chemical and biological analysis. The biosensors we are investigating couple the remarkable specificity of some biological molecules with a signal transducer to allow the detection of a single species in a complex media, such as blood, without sample preparation.

Our target applications are for environmental monitoring and biomedical diagnostics. Other applications for our modified surfaces are for the development of biomaterials and in fundamental work on molecular electronics.

Projects from our laboratory that will be discussed are:

  • DNA modified electrodes for detecting pathogens, drug compounds and DNA damage.
  • Peptide modified arrays for detecting multiple heavy metals on a single chip.
  • Immunosensors for pesticide detection in environmental analysis.
