Abstract The size‐ and shape‐dependent localized surface plasmon properties of metallic nanoparticles (NPs) enable nanoscale‐enhanced near‐field applications in a wide range fields, including spectroscopy, nonlinear optics, sensing. Orderly assembled NPs can construct plasmonic metamaterials for light manipulation at subwavelength scale, exhibiting new collective resonant modes regulated by cou...

Periodic micro and nano-structured surfaces in nature are responsible for functionalities including structural colour, superhydrophobicity, where wrinkling plays a significant role. The Bouligand architecture of fibrous composites such as insect exoskeleton plant cell walls has been shown to generate uniaxial single multiscale nanowrinkling through the chiral capillarity effect due anisotropic ...

• Report formulation of nanohydroxyapatite (nanoHA) based ink for dip pen lithography (DPN). 30-50 % (wt/Vol) Glycerol in isopropyl alcohol is necessary to achieve the required viscosity 5-15 cP printing nanoHA (3 w/v %)-formulated ink. Ultra sonication glycerol formulated aided disperse well nanoparticles get ~200 nm size and helped controlled The optimal consisted 30% 3 with printed features ...

Abstract Indirect bandgap of multilayer molybdenum disulfide has been recognized as a major hindrance to high responsivity MoS 2 phototransistors. Here, overcome this fundamental limitation, we propose structural engineering via nano-patterning using block copolymer lithography. The fabricated nanoporous , consisting periodic hexagonal arrays hexagon nanoholes, includes abundant edges having zi...

The properties of 2D materials devices are very sensitive to the physical, chemical and structural interactions that might happen during processing. Low-invasive patterning methods required fabricate at nanoscale. Here we developed a process combines oxidation scanning probe lithography (o-SPL) oxygen plasma nanoribbon field-effect transistors nano-constrictions on few-layer MoS2 MoSe2. has dou...
