Inductively coupled plasma mass spectrometry (ICP-MS) is prominently used for analyzing elemental composition in individual cells. However, the conventional sample introduction system of ICP-MS causes damage to large mammalian cells. Now, researchers from Japan suggest an efficient method of introducing mammalian cells using a microdroplet generator (µDG) that maintains the cell’s structure without compromising elemental composition. These findings can open new avenues for the diagnosis and prognosis of diseases.

Oral mucositis is a painful condition in which the mucous membranes inside the mouth become inflamed. To help alleviate this, researchers at the Tokyo University of Science (TUS) have developed a mucoadhesive film using xyloglucan and antioxidant-rich green tea extract containing catechins. With its strong adhesive properties, the film directly adheres to the affected area. Made from accessible ingredients, this solution could provide localized relief and improve the quality of life for patients.

A group of researchers have analyzed thousands of reports from the past decade, identifying a tin-based catalyst that aids the production of formic acid, an indispensable chemical in various industries, and makes the process greener. 

A new theoretical approach is proposed to explain the nature of the well-known narrow and intense optical J-band of J-aggregates of polymethine dyes. The old approach proposed by Franck and Teller in 1938 and based on the Frenkel exciton theory does not take into account the specific properties of the main optical chromophore of polymethine dye monomers—the polymethine chain. In the new approach proposed by Egorov and based on a new fundamental physical theory—quantum‒classical mechanics, which takes into account the chaotic and regular dynamics of the transient state, the optical properties of the polymethine chain and monomers as a whole are considered as a key factor determining the unique optical properties of J-aggregates.

The Aging Research and Drug Discovery (ARDD) Meeting is thrilled to announce that Morten Meldal, Nobel Laureate and Professor of Chemistry at the University of Copenhagen, and Michael Levitt, Nobel Laureate and Professor of Structural Biology at Stanford University will join the lineup of distinguished speakers for the 12th Aging Research & Drug Discovery Meeting (ARDD2025), the World's Largest Conference on Aging Research in the biopharmaceutical industry that will transpire on August 25 - August 29, 2025 on-site at the Ceremonial Hall, University of Copenhagen, and online.

The study tackles the technical challenges of NH₃ fuel SOFC ship power systems, including slow hydrogen production, low efficiency, and limited space.

Osaka Metropolitan University scientists have developed an artificial photosynthesis technology that produces precursors of biodegradable nylon from biomass-derived compounds and ammonia.
