A European consortium has developed the Megaframe Imager, an ultrafast camera capable of recording images at one million frames per second.

It allows for cellular and sub-cellular imaging, neural imaging, biosensing, DNA and protein microarray scanning, automotive collision studies, and high-sensitivity astronomical observations.

The Megaframe Imager uses an extremely sensitive single photon avalanche diode (SPAD) device and custom-designed on-chip intelligence, in conjunction with DNA microarrays.

The researchers have demonstrated detection of viral DNA binding events using fluorescence lifetime imaging at the very low target concentrations relevant in biosensing applications, with acquisition times of less than 30 seconds.
