Using Raman Spectroscopy for the Characterization of Zeolite Crystals

March 09, 2020

Article

Recently, we spoke to Scott M. Auerbach a professor of chemistry and chemical engineering at the University of Massachusetts Amherst, about his work in the use of Raman spectroscopy for zeolite structure characterization, which has focused on a collection of nine all-silica zeolites.

Using Nanopore Sensors to Analyze and Characterize Heparin and Other Therapeutic Polysaccharides

February 05, 2020

Article

Solid-state silicon nitride (SiNx) nanopore sensors can be used to analyze natural and synthetic oligosaccharides and polysaccharides like the anticoagulant drug heparin. These sensors are providing an understanding of nanopore electrokinetics-mechanisms important for capillary electrophoresis with often outsized importance on the nanoscale. Recent work in the use of nanopores is providing a platform for the development of new assays applicable to clinical analysis for a variety of therapeutic molecules. Nanopore sensors can be combined with spectroscopic techniques for multiple analytical applications. Recently, we spoke to Jason R. Dwyer, of the University of Rhode Island (USA) and a FACSS Innovation Award winner from the 2019 SciX conference, regarding his work in this field. This interview is part of a series of interviews with the winners of awards that are presented at the SciX conference.
