Camouflaging nanoporous silicon particles by functionalizing them with membranes isolated from white blood cells can delay their removal from the body and improve their accumulation in tumours.
A supramolecular polymer with embedded nanostructured Ni particles shows mechanical and electrical self-healing capabilities as well as piezoresistive properties, making it a good candidate for electronic skin applications.
Nanomechanical signatures of human breast biopsies obtained using an atomic force microscope show close correlation between softening of cancer cells and progression of cancer.
Spin can be injected into silicon from a ferromagnetic contact and across a graphene barrier with resistance-area products up to one thousand times lower than with comparable oxide tunnel barriers.
The efficiency of solar cells with high-area, nanostructured surfaces is limited by surface and Auger charge-recombination processes, which can be slowed through appropriate levels of junction doping.
Nanotwinned copper nanopillars without any grain boundaries or other microstructural features are fabricated and used to explore the influence of twin boundaries on the mechanical properties of these structures.
Lentil-shaped phospholipid vesicles are sensitive to shear stress, offering a new class of materials that can deliver drugs in response to rheological changes in the body.
Silicon nanowires configured as field-effect transistors can be used to quantify the binding affinities and kinetics of protein interactions, offering a sensitive tool for disease diagnosis and drug discovery.
A single molecule of the antibody immunoglobulin G can self-assemble with two gold nanoparticles to fabricate a protein transistor in a highly reproducible manner.
Chickens acutely exposed to polystyrene nanoparticles are less efficient at absorbing iron across the epithelial cells of their intestines than chickens chronically exposed and those that are not exposed at all.
The electrophoretic mobilities of ions in membranes made of subnanometre carbon nanotubes are approximately three times higher than the bulk values, and the induced electro-osmotic velocities are four orders of magnitude faster than those measured in conventional porous materials.
Photoluminescence microscopy can be used to image exciton quenching in semiconducting single-walled carbon nanotubes during the early stages of chemical doping.
