Dec 03, 2021 (Nanowerk News) Chronic wounds are deep and difficult to repair. Often, the top of the injury heals before the bottom, so the wound collapses in on itself. Over time, this can result in scar tissue and reduced skin function. In APL Bioengineering ("A suspended layer additive manufacturing...
Immune system-stimulating nanoparticle could lead to more powerful vaccines
Dec 03, 2021 (Nanowerk News) A common strategy to make vaccines more powerful is to deliver them along with an adjuvant — a compound that stimulates the immune system to produce a stronger response. Researchers from MIT, the La Jolla Institute for Immunology, and other institutions have now designed a...
Combining nanotechnology and optics, hybrid synapses to treat retinal dystrophies
Dec 03, 2021 (Nanowerk News) HyVIS, the European project coordinated by the IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology), is about to start. By combining nanotechnology and optics, it will develop bionic synapses for retinal prostheses, designed to restore sight in people suffering from diseases such as retinitis pigmentosa...
Using green tea as reducing reagent for the preparation of nanomaterials to synthesize ammonia
Dec 03, 2021 (Nanowerk News) Compare with bulk graphitic carbon nitride, the optimal sample had 2.93-fold photocatalytic nitrate reduction to ammonia activity (2.627 mg/h/gcat), and the NH3 selectivity increased from 50.77% to 77.9%. They published their approach in Energy Material Advances ("A Green Synthesis of Ru Modified g-C3N4 Nanosheets for Enhanced...
Researchers develop novel 3D printing technique to engineer biofilms
Dec 03, 2021 (Nanowerk News) Anne S. Meyer, an associate professor of biology at the University of Rochester, and her collaborators at Delft University of Technology in the Netherlands, recently developed a 3D printing technique to engineer and study biofilms—three-dimensional communities of microorganisms, such as bacteria, that adhere to surfaces....
Are microgrids a key to grid resiliency?
Dec 03, 2021 (Nanowerk News) The aging energy grid is being pushed to the breaking point. Power outages from extreme weather alone cost anywhere from $2 billion to $77 billion per year. And some isolated communities still rely on diesel generators for electricity, since powerlines don’t reach them. Grid expansion...
Development of a single-process platform for the manufacture of graphene quantum dots
Dec 03, 2021 (Nanowerk News) Graphene consists of a planar structure, with carbon atoms connected in a hexagonal shape that resembles a beehive. When graphene is reduced to several nanometers (nm) in size, it becomes a graphene quantum dot that exhibits fluorescent and semiconductor properties. Graphene quantum dots can be...
Novel two-step mechanism revealed in two-dimensional material formation
Dec 03, 2021 (Nanowerk News) Two-dimensional materials exhibit highly desirable properties for advanced technologies, such as flexibility, superconductivity and more. Yet the mechanism by which they become has eluded scientists for some time. Through a novel monitoring and analysis method, researchers have revealed a critical mechanism in the development of...
Building better tools for biomanufacturing
Dec 03, 2021 (Nanowerk News) A team of researchers from the Georgia Institute of Technology has developed an analytical tool designed to improve the biomanufacturing process of advanced cell-based therapies. Their Dynamic Sampling Platform provides a real time analysis of cells as they are modified and grown for treatment in...
Light-powered soft robots could suck up oil spills
Dec 02, 2021 (Nanowerk News) A floating, robotic film designed at UC Riverside could be trained to hoover oil spills at sea or remove contaminants from drinking water. Powered by light and fueled by water, the film could be deployed indefinitely to clean remote areas where recharging by other means...
