A research group at Osaka Metropolitan University has developed a drug delivery system that activates a strong cellular immune response to attack cancer cells, using one-tenth of the amount of antigen needed in the group’s previous work. By incorporating positively charged cationic lipids into liposomes and adding negatively charged pH-responsive polysaccharides to the surface, the research group increased the uptake efficiency of liposomes encapsulating cancer antigens by dendritic cells by approximately five times, which increased cytokine production by about 100 times. This increased M1-type macrophages, which activate cancer immunity, and decreased M2-type macrophages, which promote cancer growth.

Osaka Metropolitan University scientists have successfully synthesized 3-hydroxybutyrate, a raw material for poly-3-hydroxybutyrate (PHB)—a strong, water-insoluble, biodegradable plastic used for packaging materials—from acetone and CO2. With a visible light-driven catalytic system utilizing sunlight and two biocatalysts, the researchers achieved a high conversion yield of about 80%. Mimicking natural photosynthesis, this study artificially reproduced a light reaction involving sunlight and a dark reaction fixing CO2 to synthesize the raw material for PHB. The finding is expected to contribute to solving the plastic waste problem and to reducing CO2.

Rie Makiura, Associate Professor at the Graduate School of Engineering, Osaka Metropolitan University has published a review article on the facile synthesis of nanosheet materials with precise regular nanoscale pores. In 2010, Professor Makiura’s research group succeeded in fabricating the world's first MOF (metal-organic framework) nanosheets on the surface of water using a simple low-energy process. The procedure, which involved adding drops of suitably chosen molecular components to the water surface took advantage of the same phenomenon that causes the formation of oil films and led to the creation of nanosheets of exceptional integrity and stability. In the present review article, Professor Makiura describes the MOF nanosheets developed by her group so far and provides a detailed description of their characteristics and comparison with other MOF nanosheets reported around the world. In addition, she describes the formation mechanism of the MOF nanosheets on the water surface.

Milling rice to separate the grain from the husks, produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot LED light. Their new method transforms agricultural waste into state-of-the-art light-emitting diodes in a low-cost, environmentally friendly way.

When liquid meets gas, a unique zone forms. Variable by nature, molecules can cross from one state to another, combining in unique ways to either desirable or unwanted ends. From heat escaping a mug of coffee to increasing molecular concentrations in chemical solutions, gas-liquid interfaces are ubiquitous across nature and engineering. But a lack of tools capable of precisely controlling such gas-liquid interfaces limit their applications — until now.

Researchers at Osaka Prefecture University have established an approach to identify the orientation of molecules and chemical bonds in crystalline organic-inorganic hybrid thin films deposited on substrates using Fourier transform infrared spectroscopy (FT-IR) and polarized infrared light with a 3D-printed attenuated total reflectance (ATR) unit. This inexpensive method with laboratory-grade equipment quickly reaches the crystal-structure model of even extremely thin films of less than 10 nm.

Researchers discovered, while exploring the photomechanical properties of diarylethene, that under irradiation with UV light the crystal of the compound peels off into micrometer sized crystals at a world’s fastest speed of 260 microseconds. As the material returns to its former molecular structure when exposed to visible light, the exfoliation method positions itself as a candidate for photoactuator manufacturing.
