At present, to test whether patients are tainted with staphylococcus bacteria which are also called staph, doctors take biopsy and then they send the biopsy for analysis. But recently, the researchers from University of Lowa have come up with a noninvasive and ingenious chemical probe that has the capability of detecting the presence of the commonest of staph species in a very short span of one hour. The probe is found to target staphylococcus aureus which is a very common staph species found in the community and even in hospitals. This staph species results in skin infections and it can even spread to bones and joints and at the same time it is also found to be very dangerous in patients who possess a very weak immune system.

Staph Infection CheaplyDesigning the Probe

In order to design the entire probe, the team of researchers used the fact S. aureusshreds DNA. They carried out the task of exploiting this very feature for making the probe emit light which serves as a signal for doctors proving the presence of bacterium in the human body. Post-doctoral and first author and researcher of the probe, Frank Hernandez has said that they have come up with the actual method that can be used for the detection of bacteria with a very simple approach which is very fast, cheap and reliable. James McNamara, assistant professor in the field of internal medicine and corresponding author has said that they have developed a fresh method that can be used for the detection of staph bacteria which would take very less time in comparison to the time taken by the present approaches in diagnosis of staph bacteria.

Two Molecules make the Probe

There is a very exclusive feature on which the design of the ingenious probe is based. The probe is a simple particle that is made by the use of two molecules. One molecule has the ability of giving off light under typical conditions while the other molecule plays the role of blocking the light. As long as it is possible for the particle to stay whole, which means light-cancelling and light-giving molecules are together then there is no light that is given off. But in case the particle splits, the molecules ge

t separated and the molecule that gives off light is no longer blocked and starts giving off light. This is one exclusive feature of the probe that makes it very useful. In cases where the bacterium of staph encounters the molecules or the probe, it immediately starts slashing in a similar manner like with DNA.

Probe quickly and exclusively helps in detecting staph

The probe that has been created by the researchers works very well in the field of detecting staph bacterium. The entire team has been successful in producing such a probe that lasts for a very long time and at the same time it also possess the quality of identifying staph very quickly.
