Israeli medicine is always at the forefront of treating the most severe diseases, a recognized world leader which applies latest technological inventions in everyday practice.
One of the most interesting nano inventions of recent years has been development of a system for diagnosing cancer tumors in a neck, a head and lungs. This group of cancer includes:
- Oropharynx (the tumor affects the base of a tongue, soft palate, rear and side walls of a pharynx);
- Entire dento-facial systems.
The author of an invention named NA – NOSE ( “artificial nose”), is a professor at the University of Haifa – Hosam Haik. A whole team of physicians and scientists of the Engineering Chemistry Faculty of the Israel Institute of Technology have been working on the creation of the device.
The invention detects presence of a malignant tumor by analyzing exhaled air, without traditional complex tests which take lots of time and are painful in most cases. The device “sniffs” a patient, hence this nanotechnology was named as “nose”.
The high-tech device invented by a professor, works on the basis of gold nanoparticles. With their help five sensors detect in air samples, molecules of substances involved in formation of an initial stage of cancer.
New invention has been experimentally tested. 90 people voluntarily agreed to participate in the experiment . The majority of volunteers were cancer patients with different diagnoses, varieties and stages of the disease.
The device recorded exhalations of patients, analyzed them, and endured the verdict: if there were signs of the disease or not. The study involved more than 60 people, sensors (almost a dozen) not only analyzed composition of the exhaled air, correctly identified results of their owners, but also exactly identified the place of a malignant tumor. Obtained results were checked by mass spectrometry methods of microbial markers and gas chromatography (method of volatile components separation). Results of the check showed that Na-Nose precisely detected cancer and a place of its formation.
Cancers of head and neck are in eighth place on frequency.
Cancer of a larynx or lungs is rarely detected and correctly diagnosed in early stages, so percentage of full recovery after lung cancer is not high.
A diagnostic method, developed by Professor Haik, contributes to establishment of an accurate diagnosis, thereby providing an opportunity to start treatment on time, and chances of complete recovery of a patient increase many times!
