Scientists Have Figured out a Way to Use Bacteria for Ultrasound Imaging
Caltech scientists take made gigantic strides to improve the ways ultrasounds work in medicine. They succeeded in making leaner that tin reflect sound waves in a process like to how submarines reflect SONAR.
Before we dive into what the scientists did and how, let's dip a toe into how ultrasound actually works. Basically, sound waves are directed into the human torso, and are reflected by organs, but not much else, which is why we're able to construct images from the reflected sound. That's virtually as simple an caption of ultrasound imaging as I could formulate.
Mikhail Shapiro, an banana professor of Chemical Applied science, had the idea of using bacteria in ultrasound procedures when he learned that sure water dwelling bacterium take gas vesicles that regulate their buoyancy. Along with his team, Shapiro was able to demonstrate that these gas vesicles tin reflect sound waves.
Now, we don't use h2o dwelling bacterium for treatments, but East.Coli are actually used in probiotics. And then Shapiro tried to get the Due east.Coli bacterium to generate gas vesicles on their own, by transferring genes from the h2o home leaner; it didn't work. He tried doing the same by transferring genes from a leaner that's closer to the E.Coli family (Bacillus megaterium), only that didn't work either. What did piece of work, was a mixture from both the water dwelling bacteria, and Bacillus megatherium.
The scientists then carried out experiments on mice, and were successful in taking images of the modified Due east.Coli bacterium inside the gut.
Obviously, this is nowhere near to actual clinical trials, but the advancement is huge. It'll pave the way for looking at problems deep inside the body, where light-imaging techniques tin can't work. Shapiro intends on beingness able to not just run into the modified bacteria inside a patient's body, but also communicate with it to give it instructions on what to do adjacent — a feat, that has never been achieved before, and might just be the next big quantum in the world of medicine.
