Quality control and structural clarity of GLP-1 therapies

	Analytical Chemistry in Life Sciences
	The latest analytical chemistry news from News-Medical

With the surge in GLP-1 receptor agonist drugs for weight-loss and diabetes, manufacturers need faster, more sensitive quality control. Concentrated multibounce ATR-FTIR spectroscopy on small quantities of sample enhances sensitivity for detecting subtle structural changes, enabling rapid, label-free monitoring of peptide purity and aggregation.

			FEOX Biosensor Tracks Intracellular Iron in Stem Cell Differentiation The FEOX biosensor offers real-time insights into intracellular iron dynamics, enhancing understanding of stem cell differentiation and iron homeostasis.

			Protein Powders and Performance Boosters: Are We Testing What We’re Ingesting? Sports supplements pose safety risks due to contamination and mislabeling. Robust analytical testing and regulatory oversight are vital for consumer protection.

			Light-Based Sensor Continuously Detects Vaccine Quality A group of researchers from Purdue University and Merck & Co. Inc., referred to as Merck Sharp & Dohme Corp. in regions outside the U.S. and Canada, has recently unveiled a novel analytical tool that may assist pharmaceutical companies in enhancing vaccine production through expedited monitoring and analysis.

			Noninvasive optical system measures blood flow with precision Measuring how well blood flows to the brain is crucial for understanding a wide range of neurological issues, from strokes to migraines to traumatic brain injuries. Obtaining such measurements noninvasively, however, remains a challenge. The scalp and skull not only obstruct viewing the brain directly but also have their own blood supply, further complicating cerebral blood flow measurements.
