A team led by assistant professor Daniel Roxbury from the University of Rhode Island has developed a “smart bandage” – by combining bandage fibers with nanosensors – designed to detect wound infection by measuring levels of hydrogen peroxide.

Hard-working researchers have made impressive and life-saving advances regarding the treatment and diagnosis of COVID-19. This overview highlights why microfluidics have proved instrumental in meeting many of those milestones.

In the early 20th century, mass spectrometry (MS) was used to measure the mass of atoms and demonstrate the existence of isotopes. Now, MS is used to study a broad range of molecules including small hydrocarbons, proteins, peptides, carbohydrates and DNA.

Food contamination is not a new issue; this is why food producers take care to perform risk assessments and to keep their operations as hygienic as possible. But in recent years, the rise of a new class of contaminants has become a major concern to the industry.

This article covers the basics of nitrosamines, their related health concerns and key steps taken by health authorities to prevent such product recalls in the future.

Ultraviolet-visible (UV-Vis) spectroscopy is a widely used technique in many areas of science ranging from bacterial culturing, drug identification and nucleic acid purity checks and quantitation, to quality control in the beverage industry and chemical research. This article will describe how UV-Vis spectroscopy works, how to analyze the output data, the technique's strengths and limitations and some of its applications.

The enzyme-linked immunosorbent assay (ELISA) has proven invaluable as both a research and diagnostic tool. In this article, we will consider what an ELISA is, how it works, variations of the technique and what it can tell you.

The result of our ancestors reproducing with Neanderthals is that we present-day humans possess archaic genetic mutations from the extinct species. Through genetic analyses, scientists can infer how mutations from the Neanderthals impact the phenotypes of present-day humans. What have we learned from recent research?

In April 1845, The Franklin Expedition departed from the shores of England with a crew of 129 men aboard two ships. None of the voyagers returned. Now, DNA samples from descendants of the men is being used to help unravel the mystery of what happened to them.

The need to attain a high level of consistency and reproducibility in wine production, despite the complex interactions that impact winemaking outcomes, has brought advanced analytical technology onto the manufacturing floor of wineries worldwide.
