Researchers have made a breakthrough discovery in
identifying the world's most sensitive nanoparticle and measuring it from a
distance using light. These super-bright, photostable and background-free
nanocrystals enable a new approach to highly advanced sensing technologies
using optical fibres.
This discovery, by a team of researchers from Macquarie
University, the University of Adelaide, and Peking University, opens the way
for rapid localisation and measurement of cells within a living environment at
the nanoscale, such as the changes to a single living cell in the human body in
response to chemical signals.
