“Micro Ear” Is Yet Another Revolution

London, Feb 28, (THAINDIAN NEWS) A brand new device called micro ear might just change the realm of technology as researchers claim. The scientists back at the Glasgow University claims the revolutionary micro ear is capable of listening to all micro scale sounds thus making it audible. The researchers even claim the micro ear being able to detect sounds from cell and bacteria movements.
The technologists are now in the process of employing the sensitivity extracted by an optical tweezer in and as sensitive microphone. The optical tweezer is strong enough in measuring and modifying at pico-newton forces. Oxford physicist Dr. Richard Berry plans to put the device under test to eavesdrop upon flagella. The so called optical tweezers works by suspending tiny electrically-charged beads within a single beam of laser light. The scientists have already tested the micro ear in listening to the Brownian motion that makes up the movement of particles within fluids. However, if they wish to study the movements of flagella, they shall have to genetically engineer bacteria to enable the beads to stick to the flagella. The micro-ear will probably make it possible to observe natural bacteria in a much easier and hassle free manner.
The micro-ear is all destined to find some heavy applications in the medical field. Chances are that the researchers hope to determine the movement of human trypanosome parasite, that is believed to be causing sleeping sickness. So, once the movement through human blood is determined, the doctors and scientists might hit upon some new discoveries in medicine to stop the bacteria’s flagellum.
