Researchers have developed the first non-invasive method for detecting malaria infections using laser beam scanners. The painless test seems to be 100% accurate and does not require the use of any blood.
At present, the standard test for malaria detection is whether blood smears under the microscope contain deadly parasites. Diagnosis requires technicians, expensive equipment and time, and it is difficult to provide these in the poorer and more remote parts of the world. But the so-called "steam nanobubble" technology will no longer require any blood. Texas Department researcher Dmitry said that it only requires one person to place a finger on the laser device. He said: "A very short light pulse shines on our skin. Light pulses of this wavelength are only absorbed by Plasmodium and explode." When heated by a laser, tiny bubbles form within the crystals of infected cells. When the bubble bursts, they have a unique acoustic signature that scientists can hear and count. "You can find several infected cells in countless normal cells," he said.
Dmitri said that the equipment experiment has no false positive results, making the nano bubble technology extremely accurate. In the initial stages of malaria infection, treatment is very important. This is a rapid, non-invasive test for detection of malaria infection by Plasmodium falciparum, which is transmitted by a short laser pulse to steam nanobubbles. He said: "Every device will be able to screen and test more than 200,000 people every year. And it can be used by non-medical personnel to diagnose malaria cases."
Dmitry said that this beam is weaker than the laser and has been shown to be safe. The next step was a clinical trial of malaria in patients at a hospital in Houston. Shortly thereafter, the 2014 global clinical trials were conducted.
