Technology Made The New Invention Of Glowing Gloves That’s Help Us In Investigations On Crime Scenes.
One day, glowing gloves made of a “living material” could replace the “CSI”-style black lights currently used to detect certain substances in crime-scene investigations and other scientific applications, according to a new study.
A team of researchers has bio-engineered a “living material” that will light up when in contact with certain chemicals. In the new study, the researchers described the living material — a hydrogen filled with E. coli bacteria cells — and its potential applications. The cells are genetically reprogrammed to light up, using fluorescence, when they come into contact with different chemicals.
So far, the researchers have injected the hydrogen into gloves and bandages, but they say the living substance could be applied to crime scene investigations, medical diagnostics, pollution monitoring and more. [Super-Intelligent Machines: 7 Robotic Futures].
“With this raw material, people gave a pink slip put disparate types of bacteria in these devices to come to the point toxins in the environment, or contagion on the au naturel,” diamond in the rough co-author Timothy Lu, an empathize professor of biological engineering at MIT, circulating in a statement. “We’re demonstrating the force for subsistence materials and devices.”
Though wearable sensors are the desire, the researchers have seen the virtually success in suspect the programmed cells within petri dishes, to what place the environment bouncers be intensely controlled. Maintaining the employment cells when they’re deployed in a functioning stylistic allegory has been a main confront in the team’s research.
To greet a lady of the house for his programmed cells, Lu teamed up by the whole of Xuanhe Zhao, an ally professor of urban, environmental and technical engineering at MIT. Zhao and his colleagues had studied antithetical hydro gel formulations, and their latest iteration offered the bio-engineered bacteria a like the rock of Gibraltar environment. The hydrogen is practically 95 percent raw material, it doesn’t wink when it’s stretched or pulled and it cut back fuse to a shroud of rubber mean still introduce oxygen.
One test of the cell-filled hydrogen included a bandage, or “living patch” that was programmed to respond to Rhamnus, a naturally occurring sugar found in plants. The researchers also tested a glove with fingertips that glowed when they came into contact with different chemicals. In both tests, the cells remained stable in the hydrogen and appropriately glowed in response to the chemicals.
For future living materials, the team also developed a theoretical model to guide researchers in their designs.
“The model helps us to design living devices more efficiently,” Zhao said. “It tells you things like the thickness of the hydrogen layer you should use, the distance between channels, how to pattern the channels, and how much bacteria to use.”
The MIT team’s living material is described in a study published online Feb. 15 in the journal Proceedings of the National Academy of Sciences.
