Seoul, Korea: A type of soil insect called nematode has now been successfully tested for cancer by placing a type of microscopic nematode on a microchip.
Preliminary experiments showed that microscopic nematode worms “Cenorbiditis alginate” (C-alginus) placed on a microchip are more attracted to chemicals secreted by lung cancer. Instead of non-cancerous chemicals, they creep in the presence of carcinogenic compounds.
Professor Neri Jing of Myeonggi University in South Korea and colleagues insist that this method will soon become a regular diagnostic test.
We’ve previously trained mice and dogs to detect cancer, and had some success. Grace frogs are also great insect experts and can detect food, especially bacteria and fungi. Earlier, they were seen heading towards the urine of cancer patients.
Cancer cells contain a special compound called to-ethyl-one-hexanol, which attracts nematodes with a specific smell. Then the scientists developed a slide with a nematode about 1 mm long at its center. Insects were collected on opposite walls of the hive. Then a drop of cancerous cells was dropped on one side and a drop of non-cancerous cells was dropped on the other side. An hour later, the nematodes were seen going down a precancerous decline.
It turns out that this tiny device can detect cancer with 70% accuracy. Although it is not suitable for medical examinations, it can be improved after training the insects.
Some experts believe that nematodes have a good memory of different scents and fragrances. Then it is very easy to breed, keep and train these insects. The investigation was also presented at the annual meeting of the American Chemical Society in San Diego.
