Dynamics Imaging of Biomolecular Assemblies

 

Facilities

We integrate the state-of-the-art biophotonics techniques for non-invasive fluorescence studies of biological and biomolecular systems. Our multimodal fluorescence microscopy and spectroscopy techniques enable us to gain a multi-dimensional perspective of molecular mechanisms that underlie a given biological process. We use a variation of the following techniques in our laboratory (see images below) for "ensemble" and "single-molecule" studies:

  • Two-Photon Fluorescence Microscopy
  • Two-Photon Fluorescence Lifetime Imaging Microscopy (FLIM)
  • Fluorescence Correlation Spectroscopy (FCS)
  • Fluorescence Resonance Energy Transfer (FRET)
  • Laser Scanning Confocal Fluorescence Microscopy (LSCM)
  • Differential Interference Contrast (DIC) Microscopy
  • Ultrafast Laser Spectroscopy
  • Spectrophotometery and Spectrofluorimtery
  • Cell and Tissue Culture
  • Image Processing and Data Analysis Algorithm
  • Electroformation Method for Model Membranes (GUVs) Assemblies

In addition, there are other shared, scientific facilities at the University of Minnesota-Duluth that are at our disposal as well and include:

Heikal Lab: Single-Molecule Imaging (257 SSB)
Heikal Lab: Cell Signaling and Metabolism (158 SSB)
