Scientists decipher how some bacteria can operate a “reverse gear”

Some microorganisms exhibit a unique kind of reversing motion that can be mimicked for drug delivery, bio-imaging
Indian scientists have found a theoretical model explaining a unique kind of motion, called direction reversing active motion, exhibited by some bacteria that feed on other microorganisms, according to a statement released by the the Department of Science and Technology on Friday. This analysis can help in building more efficient artificial micro- and nano-motors used in drug delivery and bio-imaging using the concept to incorporate a reverse gear. Bacteria move by propelling themselves with a velocity that changes direction randomly, which is called active motion. Besides bacteria, this kind of motion is found in living systems ranging from cells at the microscopic scale to the flocking of birds and fish schools at the macroscopic scale. It is also seen in artificial systems, including granular matter self-catalytic swimmers, and nano-motors.More Related News
