The devices are made of thin soft polymer leaves named of azobenzene, which roll when they are exposed to light. Researchers can precisely control the direction of rolling and size and pipe forms varying the intensity and polarization of light. This allows devices to be firmly but gently wrapped with curved shafts and dendrites.
“To have an intimate interface with these cells, the devices must be soft and can be in accordance with these complex structures. It is the challenge we have resolved in this paper,” says Deblina Sarkar, assistant professor and the older author of the research paper. “We were the first to show that azobenzen could even wrap around live cells.”
Researchers, who have developed a scalable fiction technique that do not require cleaning use, showed that devices can be combined with optoelectric materials that can encourage cells. Moreover, atomic thin materials can be sampled on top of the pipe, offering the options for integrating sensors and assemblies.
In addition, because they make such a narrow connection with cells, they can enable encouragement of substructural regions with very little energy. This could enable the researcher or clinic to treat brain diseases by modulating the neurons of electrical activity.
