Proteins in tears fight bacteria
Latest research has found that proteins present in human tears have disease fighting properties that help in keeping bacteria that are much bigger. Researchers unveiled the manner in which this protein works by attaching a small transistor to it. the research was undertaken by researchers from UC Irvine. The question about how tears mange to ward off harmful bacteria has been a pressing one in the scientific community. The more important part about tears is that they fight relentlessly with bacteria that are continuously trying to infect the eye. The research has revealed that tears have proteins known as lyzozymes which have antiseptic properties. These lyzozymes guard the surface of the eye and kill bacteria that threaten to enter the body.
Proteins that have jaws
The proteins in the tear have tiny jaw like structures that capture bacteria and eat through them hungrily. The walls of the harmful microorganisms are torn apart by these proteins, in the process killing them or driving them away. Lysozymes are present in several rows along the surface of the eye. The transistors that were attached to the proteins in tears helped researchers understand this fighting methodology. According to researchers, the lyzozymes eat at the bacterial walls like a “hungry person eating an ear of corn”. The study was published in Science journal on the 20th of January.
The research used the smallest transistor
In order to track the functioning of the lyzozymes, researchers created the smallest transistor in the world. This is twenty five times smaller than the transistors that are used in present day electronic gadgets. The microphones are miniscule, with sizes as small as molecules. This transistor was used to listen to the movement of protein in the tears. According to Phillip Collins who is the co-leader of the study along with Gregory Weiss, listening to the transistor is like listening to the heart beat of the single protein molecule.
Transistor has many uses
One of the most profound aspects of the present study is the invention of the tiny transistor that has been attached to the protein in the tears. The transistor has been created after years of hard work by scientists. The researchers of the study say that the transistor can be used to analyze the manner in which cancer works. Knowing the methodology of cancer cell operation, growth and spread with the help of these transistors can help in finding affordable and effective cures.
