4. Material illuminates when exposed to chemicals on the body
MIT engineers and biologists teamed up and designed a living-cell-injected hydrogel that can illuminate when exposed to certain chemicals.
The MIT team made wearable sensors using the hydrogel with living cells that lit up after touching a surface with certain chemicals. The new material has the potential to detect chemicals in the environment and the human body.
They also created a hydrogel glove with swirling channels on the fingertips that also glowed when exposed to certain chemicals.
