Researchers from SANKEN (The Institute of Scientific and Industrial Research), at Osaka University demonstrated a method for drying cellulose nanofiber (CNF) that retains the unique properties of the thickening agent. High transparency, high viscosity, and controllable viscosity were restored with simple stirring after the CNF was dehydrated from an organogel. Our powder had a much smaller volume than freeze-dried CNF, which will facilitate more efficient transport and storage. The method is expected to have a significant impact on food and cosmetics manufacturing.

An international team led by Professor Yan Xu from Osaka Metropolitan University has developed a groundbreaking nanofluidic device, named NANa, capable of stochastically capturing and digitally detecting individual proteins at cellular concentrations. This tool, vital for precision medicine, is designed to handle tiny volumes equivalent to a single cell's contents and can identify single biomolecules even in high-concentration environments. The team plans to conduct further demonstrations using actual cell samples and explore the integration of this tool with AI and biological big data. This research could potentially revolutionize personalized disease prevention and treatment.

Scientists from Thailand, France and Singapore have conducted groundbreaking research using both tiny cellulose nanofibers (CNF) and long pineapple leaf fibers (PALF) to create stronger materials. They added varying amounts of CNF to epoxy and found that 1% CNF greatly increased impact strength. PALF-epoxy composites showed significant flexibility and strength improvements. Combining CNF and PALF resulted in a remarkable increase in impact strength. The findings could revolutionize stronger material development.

A joint research group at Osaka Metropolitan University has succeeded in regulating the flow of single molecules in solution by opening and closing the nanovalve mounted on the nanofluidic device by applying external pressure. The research group fabricated a device with a ribbon-like, thin, soft glass sheet on the top, and at the bottom a hard glass substrate having nanochannels and nanovalve seats. By applying external pressure to the soft glass sheet to open and close the valve, they succeeded in directly manipulating and controlling the flow of individual molecules in solution. They also observed an effect of fluorescence signal amplification when single fluorescent molecules are confined in the tiny nanospace inside the valve. The effect can be ascribed to the nanoconfinement, which suppresses the random motion of the molecules.

A research group, at the Osaka Metropolitan University Graduate School of Engineering, has succeeded in measuring spin transport in a thin film of αNPD molecules—a material well-known in organic light emitting diodes—at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have practical applications in developing spintronics technology. In addition, while electricity has been used to control spin transport in the past, the thin molecular film used in this study is photoconductive, allowing spin transport control using visible light.
