The anticaking agent E551 silicon dioxide, or silica, has been used widely in the food industry over the past 50 years, and was long thought to be quite safe. Now, however, researchers have discovered that these nanoparticles can affect the immune system of the digestive tract.
In an effort to understand how single cells heal, mechanical engineers have developed a microscopic guillotine that efficiently cuts cells in two. Learning more about single-cell wound repair could lead to self-healing materials and machines.
Scientists report on strides made in the development of a strategy to improve the immune system's detection of cancer proteins by using 'sticky' nanoparticles that are called 'antigen-capturing nanoparticles'.
A new study sheds light on the properties of nanostructures capable of ensuring an effective integration with nerve cells, an essential quality for developing innovative systems targeting the repair of neuronal damages.
In new work, researchers could show for the first time how the third dimension can be reconstructed completely in the framework of a tomographic imaging process by rotating the sample and processing a series of tilted two-dimensional projections.
Researchers have developed a nanocellulose-alginate hydrogel suitable for 3D printing. The composition of the hydrogel was optimized based on material characterization methods and 3D printing experiments.
Researchers report they have created a TI film just 25 atoms thick that adheres to an insulating magnetic film, creating a heterostructure. This heterostructure makes TI surfaces magnetic at room temperatures and higher, to above 400 Kelvin or more than 720 degrees Fahrenheit.
