Michelin Star Spectroscopy
Researchers from Yonsei University, Republic of Korea, have developed a switchable flavor compound (SFC) loaded on a hydrogel matrix, creating a new type of enhanced cultured meat. The team employed a variety of spectroscopic techniques, including Raman, NMR and UV-Vis, to design and assess SFC’s chemical structure, thermal responsivity, as well as flavor stability. This led the team to introduce two sulfur compounds – 2-methyl-3-furanthiol and 3-mercapto-2-pentanone – known to contribute to the savory and umami flavors of cooked beef. Ultimately, the researchers were then able to achieve a flavor profile almost identical to that of traditional beef. Read the full writeup!
Direct Detection of Molecular Chirality
A new nuclear magnetic resonance (NMR) technique allows for the direct detection of molecular chirality, eliminating the need for additional chiral agents. The study presents a method that uses both electric and magnetic dipoles to differentiate between enantiomers. This innovation could streamline applications in drug development and materials science where chirality plays a critical role. Read the full writeup!

Empowering the Analytical Scientist in Everyone
In 2021, Michel Nielen, Aydogan Ozcan and Jeroen Jansen asked an important question: could the general public prove to be key in the next great phase of analytical chemistry?
“Enabling citizens to conduct their own measurements is of the utmost importance. In the 21st century, citizens are learning to gather and use their data in innovative ways,” said Jeroen Jansen, who has developed an SCiO Handheld NIR Spectrophotometer, which he uses away from the lab. “Whether it be maintaining health, improving their living environment, or examining exactly what their family is eating, citizens want to know more than ever before. The latest technological developments mean that citizens no longer have to rely on institutions for such measurements.”
