Molecular GeoBiology Labs

The Molecular GeoBiology Lab is quipped to work with molecular level interactions between organic molecules and minerals. We have a video rate atomic force microscope (AFM) and wet chemistry facilities for sample prep, nano level and bulk experiments. We apply knowledge of molecule-mineral interactions to answer questions on DNA preservation in sediments, conservation of proteins in archaeologic samples, propagation of antibiotic resistance genes in the environment, horizontal gene transfer, prebiotic polymerization and mineral facilitated evolution of life.

The AFM has several capabilities and we are here most focused toward: 

  • Imaging in air and liquids
  • Video-rate imaging in liquids
  • Flow through capabilities
  • Heating/cooling
  • Chemical force microscopy
  • Dynamic Force spectroscopy
