Scientists are thinking small, building on decades of sensor work to invent tiny detectors that can sniff out everything from explosives and biotoxins to smuggled humans.
In a study, researchers describe a simple, color-based diagnostic approach with the potential to detect target DNA sequences found in TB-causing mycobacteria– in just a fraction of the time required for established diagnostic tests.
Researchers are working to try to curb the threat that two weed species pose to nurseries, Christmas tree farms, pastures and natural areas.
How exactly atoms and molecules interact is a question of great importance. Researchers have now provided a new tool that enables scientists to get a “fingerprint” of the interactions on the atomic scale.
A new laser technique can discern the contents of used nuclear fuel and potentially boost the global security of nuclear recycling.
Using carbon nanotubes, a research team has developed a sensor that greatly amplifies the sensitivity of commonly used but typically weak vibrational spectroscopic methods, such as Raman spectroscopy.
Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface.
The Chelyabinsk meteorite either collided with another body in the solar system or came too close to the Sun before it fell to Earth. A team has analyzed fragments of the meteorite, the main body of which fell to the bottom of the Chebarkul Lake near Chelyabinsk on February 15 this year.
When chemists examined the scientific literature on yew wood chemistry, they found that reports on taxines, particularly taxine B, in heartwood of yew were ambiguous. They developed an LCMS method to detect and handle enquiries.
Acetyl fentanyl overdose deaths have recently been confirmed in Pennsylvania. If states observe clusters or increases in illicit opioid-related overdoses above expected levels, acetyl fentanyl could be involved. CDC encourages laboratories to use an ELISA test to screen specimens from suspected illicit, nonpharmaceutical opioid overdose deaths. If an ELISA test is positive for fentanyl, CDC recommends confirmatory testing by GCMS.
The September Chromatography Techniques cover story focuses on the interconnectedness of life science and chromatography developments- and how they drive each other. Other article topics include ultrapure water for RNA technologies, multi-detector GPC, noise in the lab and the pressure revolution.
With UHPLC pumps being designed to handle 20,000 psi and up, new seals must also be developed to keep up with the increasing pressure demand.
Laboratory devices specifically designed to emit less noise ensure the health, safety and comfort of all employees.
Adding multiple detectors to a GPC unit enables the system to meet the needs of today’s advanced polymer industry.
The use of ultrapure water in RNA research using in situ hybridization ensures contamination-free, reliable results.
Which comes first—is it the rapid pace of life science that drives new chromatography developments or vice versa?
