What if we had tiny machines in our body that could constantly monitor every nook and cranny of our body, and if any anomalies are found, fix them locally? This could put an end to human diseases and even augment us, surpassing biological limitations.
Deblina Sarkar is building such tiny nanoelectronic devices, which are even smaller than the size of a single cell. These devices can reside inside the cells or in between cells and lead to early detection of diseases. They can also locally treat diseases of the brain, heart, and many more bodily systems, and even help us to reverse the process of aging.
