In September, we celebrated the first anniversary of Ms. Tanya Zaliznyak joining the SoMAS staff and taking the helm at NARMIL.  Her first year has been filled with exciting accomplishments demonstrating that this facility is reaching its scientific potential. We’d like to share some of these achievements with you.

1) Developed protocols to interrogate single microbial cells and marine aerosol particles in the confocal Raman microspectrometer.

2) Produced sub-micrometer scale Raman maps of cells and engineered materials on the Atomic Force Microscope (AFM) stage by co-locating the Raman laser beam on the AFM tip.

3) Developed software scripts, pipelines and shortcuts to optimize routine Raman spectral analyses.

4) With Prof. Taylor’s group (SoMAS), refined techniques to map distributions of intracellular storage products, such as globular sulfur and polyhydroxybutyrate (Fig. 1).

Figure 1. Raman map of intracellular distributions of the lipid-like energy storage product, polyhydroxybutyrate (red area with accompanying Raman spectrum) within a marine bacterium (below arrow in right panel). Blue area is relatively rich in amino acids (blue spectrum) and proteins. Cell is approximately 2.5 micrometers long.


5) For ongoing studies in Prof. Taylor’s lab (SoMAS), improved capabilities for routine Raman-FISH single cell analyses. Technique enables recognition of photosynthetically-active phytoplankton by quantifying stable isotope incorporation into biomolecules by Raman signatures and identifying players by genetic probes (FISH = fluorescent in situ hybridization).

6) Currently assisting Prof. Taylor’s group (SoMAS) in development of novel Raman and AFM techniques to follow movement of carbon through protistan symbiotic associations, between hosts and viral pathogens, and from detritus through microbial communities. This new project is supported by the Gordon & Betty Moore Foundation and funds two new postdoctoral investigators.

7) Facilitated Profs. Knopf and J. Aller group’s (SoMAS) exploration of chemical variability in sea spray aerosols and their role in cloud formation using Raman spectroscopy (Fig. 2).

8) Assisted Ms. Yoonja Kang, Prof. Gobler’s student (SoMAS), to spectroscopically characterize how cellular storage products and pigment concentrations change when a harmful bloom-forming microalga (Aureoumbra lagunensis) enters a resting stage.

9) Facilitated Prof. Robert Aller’s group (SoMAS) in spectroscopically characterizing effects of animal-sediment interactions on biogeochemical processes near the sediment-water interface.

10) Assisted Ms. Emily Herstoff, Prof. Stephen Baine’s student (Ecology & Evolution), by performing single-cell Raman analyses on an array of cultured microalgae to characterize differences in macromolecular composition.

11) Facilitated Prof. Irena Tannenbaum (Materials Sciences and Engineering) and undergraduates in characterizing interactions between biomolecules and gold nanoparticles using Raman microspectroscopy.

12) Assisted Prof. Balaji Sitharaman’s group (Biomedical Engineering) in study of bioactivity of some novel nanocomposites for bone tissue engineering using Raman microspectroscopy.

13) Provided spectral data to Prof. Yizhi Meng’s group (Materials Sciences and Engineering) to guide establishment of a 3D spheroid model of breast microcalcifcation.

14) With Prof. Stanislaus Wong’s group (Chemistry) expanded Raman spectral characterization of carbon nanotubule functionalization, primarily for photovoltaic applications.

15) Provided spectral data to Prof. Nancy Goroff’s group (Chemistry) to enable their evaluation of methods for preparing carbon-rich and all-carbon materials via self-assembly.

Not too shabby for her first 12 months and we’re only getting started!

NARMIL was established in 2014 with a National Science Foundation Major Research Instrumentation Grant through the Division of Ocean Sciences and through matching support from Stony Brook University. This facility supports research in marine, atmospheric, environmental, biological, chemical, geological, materials sciences, and biomedical engineering, and is certainly open to other applications. The lab provides state-of-the-art instrumentation and expertise for analyses of single cells, aerosols, natural materials, engineered surfaces, minerals, biofilms, thin films, and novel synthetic materials.  The lab’s mission is to offer unique analytical solutions to chronic limitations experienced in many research areas, to enable transformative discoveries, and to educate the next generation of scientists.
