Research Synopsis:
The development of new experimental tools of bioanalytical and biophysical chemistry is of the utmost importance to understand how each molecule plays its role in biological systems. In general, I am interested in developing hyphenated imaging, separation, and mass spectrometry methods for analysis of proteins, glycans, and other biomolecules. More specifically, my research group will combine light microscopy and spectroscopy, separation techniques, mass spectrometry, and biotechnology for analysis of biomolecules in cells and tissues. Developed methodologies would be applied for qualitative and quantitative studies of biological systems and disease diagnosis.

Research Details:

Dr. Isailovic’s research group has worked on independent and collaborative projects related to qualitative, quantitative, and imaging analyses of biomolecules in environmental samples as well as biological cells and tissues. Recent projects involved the analyses of cyanotoxins, such as microcystins, in water samples collected during harmful cyanobacterial blooms in Lake Erie using liquid chromatography (LC) coupled to high-resolution mass spectrometry (MS). The students in Dr. Isailovic’s group have also been working with the collaborators on the development of materials for the removal of microcystins from water and the analyses of steroids in biofluids by LC-MS.  

The following is a list of research topics studied by his research group and collaborators using primarily MS, fluorescence, and various imaging (microscopy, MS), and separation (gel electrophoresis, HPLC, and ion mobility spectrometry) methodologies:

  • Identification and quantification of cyanotoxins in water and biofluids
  • MALDI-MS analyses and imaging of microcystins  in cells and tissues
  • The development of materials for removal of microcystins from water
  • Quantification of steroids in biofluids
  • Analyses of  peptides, proteins, glycans, and lipids by MS
  • Proteomic biomarker analyses of human saliva 
  • Visible-wavelength MALDI-MS of biomolecules
  • Quantification of proteins by fluorescence detection and MS
  • Multimodal spectral imaging of biomolecules in cells
  • Investigation of energy transfer involving fluorescent proteins
