Researchers from the Osaka Metropolitan University Graduate School of Engineering have successfully developed a new technique allowing them to observe gas molecules packing into metal-organic frameworks (MOF) using infrared spectroscopy. Their innovation was to measure polarized light absorption of guest molecules in a MOF film to deduce molecule alignment using this common piece of lab equipment. This method is the first to show guest alignment and does so in real-time, while using an accessible and easily adoptable experimental setup. A short video (4 min) recreating their spectrometer modifications can be found in the Reference section.

Researchers at Kanazawa University report in Science Advances a new method for distinguishing between enantiomers, molecules that are mirror images of each other. The procedure, relevant for the pharmaceutical industry, involves the chemical reaction of target enantiomers with color indicator compounds consisting of one-handed helical polymers, leading to solutions showing different colors in specific solvents between the enantiomers.

The missing link isn’t a not-yet-discovered fossil, after all. It’s a tiny, self-replicating globule called a coacervate droplet, developed by two researchers in Japan to represent the evolution of chemistry into biology.

When it comes to cancer, clarity is key. The ability to visualize cancerous tumors and metastatic tissue three dimensionally (3D) can help clinicians diagnose the precise type and stage of cancer, while also informing the best treatment methods. To obtain an even clearer tissue for imaging, a research team based in Japan has tested the effectiveness of specialized hydrogels. Acting as a 3D molecular network, these hydrogels can rapidly remove fats from tissues, which are a factor in tissue opacification, without losing their structure. The material is used in several biomedical devices, including contact lenses.
