Peptide nucleic acids can self-assemble into ordered architectures that are coordinated by both stacking interactions and Watson–Crick base pairing, and exhibit a variety of optical properties.
TGF-β signalling, which is important in regulating various cellular processes during development, can be optically manipulated using near-infrared light with the aid of single-walled carbon nanotubes.
Calcium phosphate nanoparticles formed naturally in the intestine aid the transport of soluble molecules from the gut lumen to immune cells of the intestinal tissue, and contribute to the immune surveillance and homeostasis of the gut.
The underlying physics of the Plateau–Rayleigh instability can be exploited during core–shell nanowire synthesis to grow diameter-modulated homostructures and heterostructures with tunable morphologies.
Racetrack memories made from synthetic antiferromagnetic structures with almost zero net magnetization allow for fast current-driven motion of domain walls.
Using a metasurface comprising an array of nanorods with different orientations and a backreflector, a hologram image can be obtained in the visible and near-infrared with limited loss of light intensity.
Near-field radiative heat transfer between two surfaces is enhanced when the cold surface is coated with a thin polar dielectric film and the gap between the two surfaces is comparable to or smaller than the film thickness.
A thermal diode with two orders of magnitude higher on/off ratio than that previously achieved can be obtained by combining normal metals and superconductors.
An atomic force microscope can be used to image and three-dimensionally reconstruct chemical groups inside a protein complex with the help of single-stranded DNA molecules that act as imaging labels.
Ionic species produced from carbon-based nanomaterials on exposure to an ultraviolet laser can be detected by the mass spectrometer, and these carbon cluster species are used to map and quantify the distribution of nanomaterials in mice.
Asymmetric dye molecules encapsulated inside single-walled carbon nanotubes align in a head-to-tail fashion to obtain a large cooperative nonlinear optical response.
Microtubules gliding across a surface coated with kinesin-1 motor proteins undergo wear; a process that energetic considerations suggest involves a molecule-by-molecule removal of tubulin proteins.
The high charge doping achieved in ionic field-effect transistors by lithium intercalation allows gate-controlled phase transitions in thin flakes of 1T-TaS2.
