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.
