New test can detect all types of cancer in minutes



A recent research has developed a rapid test that can detect all cancers within a few minutes. The test would be done on blood and biopsy tissue. The research was conducted at the University of Queensland in Australia. One of the scientists involved in the research was of Indian origin. Scientists have discovered a unique DNA nanostructure that seems to be common to all cancers.

All cancers have different signs and symptoms. Cancer is extremely complicated and difficult to detect in its initial stages.

The scientist developed a procedure that finds a simple signature that differs from healthy cells and is common in all cancers. It was a very complicated process that was considered very difficult.

"This unique DNA signature at the nanoscale For all types of breast cancer that we studied and others Forms of cancer, including prostate, bowel and lymphoma diseases, appeared "Abu Sina of the University of Queensland."

. "The concentrations and patterns of small molecules are called methyl groups. DNA is dramatically altered by cancer – these are the key methyl groups for cells to control which genes are turned on and off, "said Sina.

Researchers have also developed a tool that can be used to study these patterns and the changes that make up the genome-level pattern within minutes.

"In healthy cells, these methyl groups are distributed throughout the genome, but the genomes of cancer cells are essentially infertile, except for int ensiven groups of methyl groups at very specific sites. Laura Carrascosa, a professor at the University of Queensland, said:

Scientists also discovered that intense clusters of methyl groups cause cancer DNA fragments to fold into unique three-dimensional nanostructures when placed in solution. Later, these three-dimensional nanostructures can be easily separated by adhering to solid surfaces such as gold.

"We have developed a simple test with gold nanoparticles that immediately change color to determine whether 3D nanostructures of cancer DNA are present," said Matt Trau, a professor at the University of Queensland.

Blood signatures, "he added.

The study found that cancerous DNA molecules compared to normal circulating DNA completely different 3D nanostructures.

"This has led to the creation of cost-effective and portable detection devices that could potentially be used as a diagnostic tool, possibly with a mobile phone," said Trau.

This new technology has 90 percent accurate results were obtained from tests performed on 200 human cancers and normal DNA
