AirPods-sized fluorescence analytical device holds promise for timely home molecular testing

Advances in medical technology have improved health in part by bringing key aspects of care, once difficult to access, into the home. Tracking symptoms and even screening for certain types of illness outside of a laboratory or clinical setting puts more control into the hands of patients.

Light-driven chemistry steers electron transfers beyond redox limits

Chemists use single-electron transfers to synthesize complex, ring-shaped molecular structures found in many drug candidates and advanced materials, but current techniques still have limitations. A new study, accepted for publication in Nature, describes a technique that could steer these chemical reactions in ways that were previously limited by the redox potentials of the involved molecules.

Transforming vibrations into clean fuels and chemicals through piezosynthesis

From ocean waves and flowing rivers to the systems used to transport and treat water, vibrations are everywhere. But can vibrations do more than just shake water? Can they split water or drive the production of useful chemicals from water? A research team led by Professor Sai Kishore Ravi from the School of Energy and Environment (SEE) at City University of Hong Kong (CityUHK) has successfully demonstrated how mechanical vibrations can be harnessed to drive the production of useful chemicals from water.

Reinventing food packaging with safe and sustainable oxygen-scavenging biodegradable plastic

From ensuring that food remains fresh longer to extending its shelf life for future consumption, food packaging plays an indispensable role in modern society. Conventional food packaging plastics are sturdy and highly effective at keeping out oxygen, one of the main drivers of food spoilage.

Vapor-controlled supramolecules can switch color, glow and phase

Controlling interactions between molecules and their functions from the molecular level to the macroscopic scale is challenging in supramolecular and materials chemistry. To this end, a research team led by associate professor Yosuke Tani from WPI-ITbM at Nagoya University and Keisuke Wada from Kyoto University designed a vapor-controlled, reversible host–guest chemistry system that controls the optical and physical properties of a functional molecular liquid (FML)—nonvolatile fluids that can feature optical, electronic and catalytic properties.

Atomic channels can separate rare earth elements from each other without using toxic chemicals

Rare earth elements like lanthanum, neodymium and dysprosium are used to build the electric motor in your car, the LED lights in your house and the MRI machine at your doctor's office. But first, they have to be mined and separated from each other. Historically, that purification has been a difficult, costly process, relying on huge amounts of toxic chemicals.

Novel antibiotic candidates starve resistant bacteria by blocking vitamin supply

Bacteria have spent decades evolving resistance to virtually every antibiotic we have thrown at them. To stay ahead, new drugs must hit targets that existing antibiotics have never touched. A research team at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) has now developed a series of synthetic drug candidates that do exactly that: By blocking an essential molecular supply system, these molecules cut off the bacteria's supply of essential vitamins and starve them to death. The team published its findings in two studies in the Journal of Medicinal Chemistry.

Open-source AI predicts key peptide traits before costly lab testing

Penn Engineers have developed PeptiVerse, an AI-powered platform that predicts key chemical and biological properties of peptides, strings of amino acids whose medical potential has been demonstrated by the success of GLP-1 drugs, widely used weight-loss treatments.

How 'super' enzymes can transform recycling

From microplastics clogging up our oceans to landfills leaching dangerous chemicals, plastic waste is a serious and growing problem for human health and the environment. We need to recycle more and, crucially, recycle better.

Chemists develop a molecular platform for the selective control of oxygen reaction pathways

Controlling how oxygen reacts is important for improving technologies such as batteries, fuel cells and environmentally sustainable chemical processes. A research team led by professor Seung Jun Hwang from KAIST's Department of Chemistry has developed a molecular system capable of directing oxygen activation along a selected electron-transfer pathway.

Molecular model for semiconductor surfaces developed

Semiconductor surfaces can generally be studied only with considerable experimental effort, for example, in an ultrahigh vacuum. To more easily gain new insights into their properties and the possibilities for targeted modification, scientists at Heidelberg University have developed a molecular model for the so-called "buckled dimer" using synthetic and computational chemistry methods.

AI and quantum chemistry combine to identify efficient blue OLED materials

Organic light-emitting diodes (OLEDs) have become a standard in modern devices with incredible contrast and sleek designs. While initially an expensive luxury, OLEDs are gradually becoming more financially accessible as the technology improves. Now, researchers at the Institute of Transformative Bio-Molecules (WPI-ITbM) at Nagoya University and the Institute for Advanced Study at Kyushu University have combined quantum chemistry with machine learning to identify new materials for blue OLEDs for incorporation in next-generation ultra-high-definition displays. Their research was published in Angewandte Chemie on July 21, 2026.

Light-driven chemistry method could create antiviral compound libraries 10 to 100 times larger within weeks

As the world faces new and often untreatable viral threats, Simon Fraser University researchers have found a way to cut years off the time it takes to discover antiviral drugs. The new research enables scientists to quickly create large libraries of nucleoside analogs (NAs), compounds that mimic the building blocks of DNA and RNA and are widely used to treat cancer and viral infections such as HIV and hepatitis.

Neutral catalysts achieve chalcogen-bonding asymmetry

Chemists have demonstrated that neutral chalcogen-bond donors can induce asymmetry in chemical reactions, addressing a challenge that has limited the development of chalcogen-bonding catalysis.

Lithium ions sprint up to 10,000 times faster when their molecular cages briefly open

An international collaborative research group led by Professor Bong June Sung of the Department of Chemistry at Sogang University and Professor Shinji Saito of the Institute for Molecular Science (IMS), National Institutes of Natural Sciences (NINS), and the Graduate University for Advanced Studies, SOKENDAI, has elucidated, at the molecular level, how lithium ions move within organic ionic plastic crystals (OIPCs)—which are attracting attention as solid electrolytes for next-generation batteries.
