Materials Science and Engineering Biomaterials

Biodegradable plastics are great. They provide the ductility of plastics whilst reducing the materials environmental downsides. However, in the quest for greater degradability, improving durability has received scant attention. A research group recently rectified this with the development of a new bamboo composite that emphasised both biodegradability and strength. The group also developed a means to predict how the material breaks down in water.

A fast and efficient tool could change the way researchers collect tiny therapeutic packages from cell cultures, offering a low-cost approach that avoids lengthy processing and complex procedures.

Japanese researchers have developed a living sensor display that turns engineered skin into a biological monitor, visually indicating internal inflammation without requiring blood sampling.

Surface-bound gels may have provided the structure and chemistry for life to take root on Earth, and perhaps beyond

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, report in the Journal of the American Chemical Society the use of three-dimensional atomic force microscopy (AFM) and molecular dynamics simulations to determine the structure of water in the hydration of different types of chitin nanocrystals, and how this affects their mechanical properties, reactivities, and interactions with enzymes and reactants.

A new way to grow stem cells may help them release more of the signaling proteins they use to repair tissue, potentially improving future treatments.

Cell sheet preparation for use in tissue engineering and regenerative therapies could be significantly improved with the use of thermo-responsive polymer brushes, adjusted in length and density according to specific cell types

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, report in Small, a weekly peer-reviewed scientific journal covering nanotechnology, published by Wiley-WCH, Germany, how short peptides self-assemble linearly on atomically-thick solid surfaces, such as graphite and MoS₂. The research addresses a longstanding challenge in materials science: understanding the complex, sequence-specific interactions between peptides and solid substrates, and the critical role of local hydration structures in guiding nanoarchitecture formation. This work offers new strategies for integrating biomolecules with advanced materials in future bioelectronics and sensor devices.

Inspired by elephants, researchers grow fungus in elephant-skin patterns to create better insulation for buildings.

In a study recently published in the journal SMALL, a weekly peer-reviewed scientific journal covering nanotechnology, published by Wiley-WCH, Germany, researchers from Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, Japan, collaborating with Professor Sarikaya, Seattle, USA, used frequency modulated atomic force microscopy to reveal the molecular architecture of genetically designed and point mutated peptides and their self-organizations each forming single-molecule thick, distinct biological crystals on atomically flat graphite and MoS2 surfaces, offering a potential platform for hybrid technologies such as bioelectronics, biosensors, and protein arrays.

Vaccines and therapies based on messenger RNA could be more readily delivered due to a non-toxic polymer that protects RNA and controls its release inside cells.

In a study recently published in the journal ACS Nano, published by American Chemical Society, researchers from Kanazawa University, Kanazawa, Japan, collaborating with University of Washington, Seattle, USA, used frequency modulated atomic force microscopy to reveal the molecular architecture of a genetically designed peptide and its self-organization that forms single-molecule thick crystals on atomically flat graphite surfaces, that offer a potential platform for hybrid technologies such as bioelectronics, biosensors, and protein arrays.

Researchers are working to overcome challenges in order to bring wearable, electric, wound-healing devices to clinical practice.

A research group led by the Institute of Industrial Science, The University of Tokyo, finds that sensory neurons in human skin modulate melanocytes via the secretion of Repulsive Guidance Molecule B

Tile patterns in which the same shape is laid out without gaps are found in the compound eyes of insects. Hexagonal tile patterns are common while shrimp eyes have a square pattern. We investigated tile pattern formation using Drosophila and revealed that the compound eye tile pattern is controlled by a geometrical division mechanism, Voronoi tessellation, in addition to physical constraints determined by the combination of the regular distribution and growth of the individual eyes.

This is a novel study that attempted to construct a pH-sensitive delivery system into T cells and their subsets using carboxy-terminal Phe- and CHex-modified dendrimers with different structures, i.e. PAMAM-CHex-Phe and PAMAM-Phe-CHex. The findings contribute to the development of nanoplatforms for direct delivery to T cells to control the functions of T cells, which play key roles in cancer immunotherapy. This is the first report on direct delivery into T cells using pH-sensitive DDS.

From biomemory to implants, researchers are looking for ways to make more eco-friendly electronic components.

Researchers at Osaka City University produce malic acid, which contains 4 carbon atoms, through artificial photosynthesis by simply adding metal ions like aluminum and iron. This solves a problem with current artificial photosynthesis technology of only producing molecules with 1 carbon atom and paves the way to exploring the use of CO2 as a raw material.

A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has gained sufficient attention among researchers for introducing a powerful antifouling material, inspired from marine plants.

The Hong Kong Polytechnic University (PolyU) today announced the signing of a collaborative framework agreement with Wuyi University (WYU). The two universities will join hands for research on the development of green and healthy textile materials over a span of three years.
