Fish eye insight to illness

PROMISING PROTEIN: Dr Luigi Sasso and Dr Madhu Vasudevamurthy are researching the protein found in the eyes of hoki fish in an attempt to develop products to detect health problems in humans.

University of Canterbury researchers are using discarded fish eyes to help develop sensors that will detect health problems in humans.

They are aiming for cheap sensors that people could buy at a pharmacy and use to check for the early stages of illnesses such as cancer, allowing treatment before the illness got to dangerous levels.

The university is the only one in the world able to manufacture protein nanofibres on a large scale, and the work aims to make New Zealand a world leader in bionanotechnology research.

"The study of biological structures already found in nature can lead us to alternative methods to develop biosensors or other analytical devices from green nanofibres which can be used to detect sugar levels for diabetics, lactose [for dairy-intolerant people] and downstream indicators of diseases such as cancer," Dr Luigi Sasso said.

Working at the university's biomolecular interaction centre, he uses methods developed at the university to remove protein from fish heads that would otherwise end up in the rubbish bin.

He produces tiny nano-thin proteins that could be manipulated and used for research, and said the work was a step towards solving many health issues.


"In today's world, where humans have abused and oppressed our natural environment for our purposes, I believe it is important to learn how to work together with the world we live in, especially when it comes to technological development.

"How great would it be if you could go down to the pharmacy, pick up a cheap and easy-to-use device to check your blood for early stages of cancer, and then toss it in the recycling bin when you're done? It would allow people to be aware of their health issues way before they reach a dangerous level . . . in the end, more lives would be saved."

The university said it had received more than $1 million to launch the project, which would be breaking barriers looking at nanofibres up to 10,000 times smaller than a strand of human hair.

Bionanotechnology expert Professor Juliet Gerrard said the Canterbury University group was the only one in the world able to manufacture protein nanofibres on a large scale.
