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.
Hafnium nanoparticles that home onto microfractures in bone make the tiny cracks visible in spectral or color computed tomography (CT) imaging. Researchers at the University of Illinois at Urbana-Champaign and the University of Maryland created the nanotechnology to work in conjunction with spectral molecular imaging developed by New Zealand-based MARS Bioimaging Ltd. (MBI). The research appeared in Advanced Functional Materials.
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.
