Nano Institute of Utah

The Nano Institute of Utah provides an organization wherein scientists, engineers and clinicians from across the University, the State and elsewhere work together to attain global recognition by conquering interdisciplinary challenges in nanoscience and nanotechnology. The Institute enables Utah researchers from disciplines such as chemistry, physics, biology, engineering, medicine, and pharmacy to create synergistic alliances to drive higher levels of collaborative research, education and commercialization.

June 2014 Cover Feature

Jonathan J. Schaefer, Alexis C. Crawford, Marc D. Porter, and Joel M. Harris (Department of Chemistry and the Nano Institute) were honored to have their article “Confocal Raman Microscopy for Investigating Synthesis and Characterization of Individual Optically Trapped Vinyl-Polymerized Surfactant Particles” featured on the cover of Applied Spectroscopy’s June Issue.

Optical trapping confocal Raman microscopy is a spectroscopic method capable of acquiring information at several stages of development of dispersed particulate materials. For this research, the scientists developed an adsorbent material, and employed confocal Raman microscopy to characterize each stage of the process. As shown in the false color SEM image on the cover, vinyl polymerization of extruded dispersions of sodium 11-acrylamidoundecanoate, under experimental conditions, produces stable spherical particles.

 ChemistryWorld recently published "Catching viruses associated with cervical cancer"

Cervical CancerRoss Stevenson and co-workers at the University of Strathclyde and Renishaw Diagnostics have developed a quick and efficient bioassay that uses surface-enhanced Raman scattering spectroscopy (SERS) to differentiate between different HPV genotypes. Bringing this promising technology closer to the clinic is of vital importance for the development of high throughput diagnostics and in principle it will be possible to create individualized patient management strategies according to what type of HPV is present. Analytical chemistry expert Marc Porter, USTAR Professor from the University of Utah commented in the article that ‘SERS is poised to move from the research laboratory into the realm of clinical diagnostics’.

Fast test classifies meningitis bacteria

MenengitisKaren Faulds’ group at the University of Strathclyde, Glasgow, have developed a new method that uses surface enhanced Raman scattering (SERS) to quickly identify which meningitis causing bacteria is responsible f for an infection. Combining the SERS technique with chemometrics means the amount of bacteria in a sample can be measured whilst simultaneously identifying the bacteria. This would be particularly useful where co-infection of multiple species is common. Identifying the dominant pathogen present would allow targeted treatment.Marc Porter, USTAR Professor, whose group at the University of Utah uses SERS to examine biomarkers, says the ability to identify and concurrently quantify three common meningitis bacterial pathogens is impressive. According to Dr. Porter, ‘The work takes an important step in moving SERS and nanoparticle-based signalling much closer to meeting a critical need in pathogen detection’.
