An progressive scientific instrument developed by College of Hawaiʻi at Mānoa researchers is predicted to be a recreation changer within the seek for life — present or extinct — on Earth and different planets.

The instrument, known as a Compact Coloration Biofinder, makes use of specialised cameras to scan massive areas for fluorescence alerts of organic supplies like amino acids, fossils, sedimentary rocks, vegetation, microbes, proteins and lipids.

The instrument has detected these bio-residues in fish fossils from the 34- to 56-million-year-old Inexperienced River rock formation situated in Colorado, Wyoming and Utah. 

The findings are printed in Nature Scientific Stories.

“The Biofinder is the primary system of its type,” stated Anupam Misra, lead instrument developer and researcher on the Hawaiʻi Institute of Geophysics and Planetology at UH Mānoa’s Faculty of Ocean and Earth Science and Expertise.


“At current, there isn’t any different gear that may detect minute quantities of bio-residue on a rock through the daytime,” Misra stated.” Extra strengths of the Biofinder are that it really works from a distance of a number of meters, takes video and might shortly scan a big space.”


The seek for life on different planets is a serious objective of exploration missions carried out by NASA and different worldwide area businesses.

“If the Biofinder have been mounted on a rover on Mars or one other planet, we’d have the ability to quickly scan massive areas shortly to detect proof of previous life, even when the organism was small, not simple to see with our eyes, and useless for a lot of tens of millions of years,” Misra stated. “We anticipate that fluorescence imaging might be vital in future NASA missions to detect organics and the existence of life on different planetary our bodies.”

Misra and his colleagues are making use of for a possibility to ship the Biofinder on a future NASA mission.


“The Biofinder’s capabilities can be vital for NASA’s Planetary Safety program, for the correct and no-invasive detection of contaminants equivalent to microbes or extraterrestrial biohazards to or from planet Earth,” stated Sonia J. Rowley, the staff biologist and co-author on the examine.

“The detection of such biomarkers would represent groundbreaking proof for all times outdoors of planet Earth,” Misra stated.

Although the Biofinder was first developed in 2012 by Misra, advances supported by the NASA Planetary Instrument Ideas for the Development of Photo voltaic System Observations (PICASSO) program culminated within the newest shade model of the compact Biofinder.

Discovering proof of organic residue in an enormous planetary panorama is a gigantic problem. The staff examined the Biofinder’s detection skills on the traditional fish fossils within the Inexperienced River formation and corroborated the outcomes by means of laboratory spectroscopy evaluation, scanning electron microscopy and fluorescence lifetime imaging microscopy.

“There are some unknowns concerning how shortly bio-residues are changed by minerals within the fossilization course of,” Misra stated. “Nonetheless, our findings affirm as soon as extra that organic residues can survive tens of millions of years, and that utilizing biofluorescence imaging successfully detects these hint residues in actual time.”
