Abstract Nano-objects, such as quantum dots (QDs), are essential units for the construction of functional materials and devices in current technologies. The establishment a versatile scheme to sort desired components from crude product is crucial bringing out full potential original materials. However, it still challenging separate QDs with same composition on basis size but different optical p...

Plasmonic nanostructures with a negative Poisson ratio are demonstrated, having the unusual mechanical property of auxetics to expand laterally when being stretched. Using nanomembrane technology, auxetics are shrunk by orders of magnitude, giving simultaneous access to optical properties of plasmonic metamaterials, as well as auxetic mechanical properties on the nanoscale.

Rapid controlled self-assembly makes DNA ideal for building nanostructures. A problem using hybridized intermediates in hierarchic assembly is their thermodynamic lability. We demonstrate a click-fixation technology by which robust hexagonal DNA modules can be made. This principle is applicable to a wide variety of DNA nanoconstructs.

skeletal muscle is a highly differentiated tissue with very specific functions which has low potential of regeneration. skeletal muscle injuries especially in athletes almost have lead to muscular dysfunctions and healing may be prolonged for several years. therefore, working on skeletal muscle differentiation remained an importance in biomedical researches. adipose derived stem cells (adscs) a...

Surface-modification of the elastomer poly(dimethylsiloxane) by exposure to oxygen plasma for four minutes creates a thin, stiff film. In this study, the thickness and mechanical properties of this surface-modified layer were determined. Using the phase image capabilities of a tapping-mode atomic-force microscope, the surface-modified region was distinguished from the bulk PDMS; specifically, i...
