Detecting viruses with light: Breakthrough in sound science
Do viruses make sounds? It turns out they do, and scientists have developed a method to detect the acoustic vibrations of viruses using light. This discovery could have a significant impact on medicine and the food industry, helping to detect harmful pathogens and even cancer cells.
Scientists at Michigan State University have developed an innovative method to detect the acoustic vibrations of individual virus particles using light. Although we cannot hear these sounds, they offer valuable insights into biological research. But how is it possible for such tiny organisms to make sounds? It's a matter of physics, not structure, as every movement of atoms emits sound. Even though viruses are invisible to the naked eye, they are complex entities composed of a vast number of atoms.
Do viruses make sounds?
Dr. Elad Harel, the study's author, emphasizes that this method allows for the study of viruses in their natural environment. This makes it possible to quickly and accurately analyze their behavior without the need for complex labeling. This streamlines the entire process, reduces costs, and could facilitate the study of bacteria or the detection of cancer cells in the future.
The main method of biological research is the labeling of tissues and cells, which, on a basic level, looks quite similar. Labeling is used to differentiate various types of cells within an organ or distinguish between healthy and diseased tissue. This is most commonly done with proteins that stand out with different colors or other measurable properties. Based on these markers, analysts can form an image of the composition of a given biological sample.
Revolution in treating viral infections
BioSonics, the new research method, enables real-time observation of what a single virus particle does. This can aid in understanding how viruses function and how their replication can be disrupted by new antiviral drugs. The technology may also be used to create non-invasive sensors for detecting viruses from a distance, enabling the monitoring of food safety or airport security checks.
Although the research is still in its early stages, its potential is enormous. This method may also assist in distinguishing active virus particles from inactive ones, which is crucial in diagnosing infections.
