World’s fastest camera takes on biosensing
TEDDINGTON, UK – A new ultrafast camera will have applications
in biological processes as well as automotive collisions and astronomical observations.
The Megaframe Imager can record images at 1 million fps, far faster than the normal
video rate of 24 fps.
But thanks to a single-photon avalanche diode device and bespoke
on-chip intelligence, higher-than-video speeds are achievable, which opens up a
new range of previously unthinkable applications, from cellular and subcellular
imaging to neural imaging, from biochemical sensors and DNA/protein microarray scanning,
to automotive collision studies and even highly sensitive astronomical observations.
The camera was developed by a European consortium made up of the
National Physical Laboratory, ST Microelectronics, the University of Edinburgh and
TU Delft. The research team has reported detection of viral DNA binding events using
fluorescence lifetime imaging at low target concentrations, needed for biosensing
applications. The acquisition times in the current study were less than 30 seconds.
The results were reported in the Optical Society of America’s
new journal Biomedical Optics Express, Vol. 1, Issue 5, pp. 1302-1308 (2010).
