High-speed atomic force microscopy imaging in liquid reveals the variability of the onset of cell death induced by antimicrobial peptides on a cell-by-cell basis.
The response of polyhydroxy fullerene and other functionalized fullerenes to low levels of laser irradiation could be exploited in a variety of applications.
Suitable distributions of vertical posts, prepared by electron-beam patterning of an inorganic resist, can be used to template complex patterns in a cylindrical block copolymer.
Magnetic levitation of cells with a hydrogel containing magnetic nanoparticles forms a three-dimensional tissue culture suited for various multicellular studies.
Theoretical simulation predicts that unless very small nanoparticles are shown to be safe, there is no combination of nanoparticle size and concentration that will deliver optimal sun protection while being safe and aesthetically appealing.
Ultradrawn polymer fibres with diameters of 50–500 nm and lengths up to tens of millimetres have been prepared, and found to show thermal conductivities as high as ∼105 W m−1 K−1.
Bond-cleavage and bond-forming reactions can be performed at local positions on a DNA origami scaffold and imaged at the single-molecule level with atomic force microscopy.
A spintronic device in which the input, output and internal states are all represented by spin, and that shows the five essential characteristics necessary for logic applications, is proposed.
A continuous semiconducting thin film can be created from a large sheet of graphene, which does not have a bandgap at room temperature, using block copolymer lithography.
Dynamic changes in the light-driven proton pump, bacteriorhodopsin, which occur on stimulation with light, can be visualized using high-speed atomic force microscopy.
Ultrasharp scanning probe microscope tips made of diamond-like carbon that contains silicon and oxygen demonstrate very high levels of wear resistance.
The quantum Hall effect has been measured in epitaxial graphene to an accuracy of a few parts per billion, potentially establishing a new quantum resistance standard.
Biological nanofactories selectively bind to bacteria and produce molecules that trigger a quorum sensing response and facilitate the communication with nearby bacteria, offering a way to generate new antimicrobial treatments.
