Researchers from The Hong Kong Polytechnic University (PolyU) said they have used two-dimensional nanosheets (FePSe3) to develop a biomimetic nanosheet that can monitor tumor development, treat tumors and monitor the treatment progress in real-time. With positive results from mice, the team hopes to further test it on larger animals, then move on to clinical studies.
Two decades after the federal government jumpstarted U.S. R&D investment in its understanding and control of nanoscale matter, funding for the efforts across the government reached about $1.4 billion in fiscal 2020, part of a total cumulative investment of about $29 billion. Though FDA-budgeted nanotech research has accounted for just a fraction of that, at a modest $133 million since 2009, substantial advances have still been made, according to a presentation on the state of nanotech progress and innovation issued this summer.
Monitoring the electrical activity within and between cells on a large scale in a living animal may seem like a task that's next to impossible. But that's precisely what researchers at Cambridge, Mass.-based Harvard University aim to do with the next iteration of nanoscale sensors in the shape of wires.
