Biotherapeutic drugs present new analytical challenges to the drug development and quality control process. Unlike traditional small molecule drugs where synthetic choices can be tightly controlled, biotherapeutic drugs rely on the integrity of host cell biosynthetic machinery to manufacture the drug. The host cells themselves also present an issue where the biotherapeutic product can be contaminated with trace amounts of host cell proteins (HCPs).

The Isotopic Detection of Aminosugars With Glutamine (IDAWG) method was originally developed for the glycomics field as a quantitative tool that takes advantage of the hexosamine biosynthetic pathway, isotopically labeling nitrogen-containing glycans in cell culture systems via the use of ¹⁵N-Gln^1,2.

Polymer interface science is broadening its area to nanotechnologies, medicine, and biotechnology.

Microbial volatile organic compounds (MVOCs) like ketones, alcohols, terpenes, and terpene derivatives are primary and secondary metabolites of fungi and bacteria¹ . Indoor environments with varying amounts of humidity, lack of light, oxygen, and carbon dioxide create the breeding ground for MVOCs. Prolonged human exposure to MVOCs has been directly associated with sick building syndrome (SBS), respiratory irritation, and asthma-like symptoms¹ .

The field of art conservation relies on many analytical techniques that are also used in the field of chemistry. Art comes in many forms from paintings, to sculptures, to written word. Each work of art can be chemically unique, as well as chemically and structurally complex.

Dramatic advances in the understanding of X-ray absorption fine structure (XAFS) have been made over the past few decades, which have led ultimately to a highly quantitative theory. X-ray absorption fine structure (XAFS) refers to the oscillatory structure in the x-ray absorption coefficient just above an x-ray absorption edge. This turns out to be a unique signature of a given material; it also depends on the detailed atomic structure and electronic and vibrational properties of the material.

Since the 1950s, plastic production has steadily increased with millions of metric tons accumulating in the environment.¹ Much of the waste stream is single use plastics, and the need for biodegradable alternatives is pressing. Polyhydroxyalkanoates (PHA), a class of polymers produced by many bacteria as a carbon source, presents a viable biodegradable replacement for many commodity thermoplastics such as polypropylene and polyethylene.

Eric Ferreira’s own early fascination with solving puzzles helps him inspire students to piece together the logic behind organic chemistry.

Dr. Melanie Reber, assistant professor in the UGA Department of Chemistry, has been named one of two Innovation Fellows for Spring 2021. Launched as part of the University of Georgia’s campus-wide Innovation District initiative, the semester-long fellowship helps faculty align their research activities with industry needs and bring their discoveries to the marketplace.
