Anasys Licenses ORNL Nanoscale Mass Spectrometry Imaging Technology

(Nanowerk News) Anasys Instruments Corp. has licensed a Department of Energy Oak Ridge National Laboratory technology that allows for simultaneous chemical and physical characterization and could lead to advances in materials and drug development.
The technique, which combines the power of atomic force microscopy and mass spectrometry, fills a void and streamlines analytical processes that are vital to science and industry, said Roshan Shetty, chief executive officer of Anasys Instruments. He also noted that the technology improves the current spatial resolution of ambient methods for mass spectrometry imaging by a factor of more than 100, resulting in imaging resolution as small as 250 nanometers, or 1/400th the thickness of a human hair.

A heated atomic force microscope cantilever probe touches a surface to be analyzed with vapor from surface material that is thermally desorbed. The heat is drawn into the ion source of the mass spectrometer, ionized and then detected and analyzed by a mass spectrometer.
“This capability could have a tremendous impact on a broad field of applications in materials and life sciences ranging from single-cell imaging to polymer composites,” Shetty said.
The license is the culmination of several years of research by a team led by Gary Van Berkel of ORNL’s Chemical Sciences Division. The team’s research has focused on mass spectrometry-based imaging pushing toward nanoscale imaging at ambient conditions using atomic force microscopy.
“No other group has these capabilities, and this research distinction made Oak Ridge National Laboratory the ideal partner,” Shetty said.
Van Berkel noted that the patented technique opens a world of opportunities.
“This new capability allows us to map, for instance, the degradation of organic compound-based solar cells at the chemical level, the metabolites produced from living bacterial colonies and the distribution of dosed pharmaceuticals and their metabolites in tissues and cells,” Van Berkel said.
Measurements of physical and chemical processes using these new tools could provide the knowledge required to boost research in areas ranging from energy materials to drug discovery, according to Van Berkel.
Anasys Instruments, located in Santa Barbara, is a leader in the field of nanoscale imaging and analytics and expects to have a commercial product available sometime in 2015. More information about Anasys is available at http://www.anasysinstruments.com.
Others members of the invention team are Stephen Jesse of ORNL’s Center for Nanophase Materials Sciences and Olga Ovchinnikova, also a member of the Chemical Sciences Division. The research was funded by DOE’s Office of Science.
