Scanning probe block copolymer lithography.
Integration of individual nanoparticles into desired spatial arrangements over large areas is a prerequisite for exploiting their unique electrical, optical, and chemical properties. However, positioning single sub-10-nm nanoparticles in a specific location individually on a substrate remains challenging. Herein we have developed a unique approach, termed scanning probe block copolymer lithogra...
متن کاملSingle-molecule protein arrays enabled by scanning probe block copolymer lithography.
The ability to control the placement of individual protein molecules on surfaces could enable advances in a wide range of areas, from the development of nanoscale biomolecular devices to fundamental studies in cell biology. Such control, however, remains a challenge in nanobiotechnology due to the limitations of current lithographic techniques. Herein we report an approach that combines scannin...
متن کاملAdvanced oxidation scanning probe lithography.
Force microscopy enables a variety of approaches to manipulate and/or modify surfaces. Few of those methods have evolved into advanced probe-based lithographies. Oxidation scanning probe lithography (o-SPL) is the only lithography that enables the direct and resist-less nanoscale patterning of a large variety of materials, from metals to semiconductors; from self-assembled monolayers to biomole...
متن کاملA plasmonic biosensor array by block copolymer lithography†
Highly uniform and dense, hexagonal noble metal nanoparticle arrays were achieved on large-area transparent glass substrates via scalable, parallel processing of block copolymer lithography. Exploring their localized surface plasmon resonance (LSPR) characteristics revealed that the Ag nanoparticle array displayed a UV-vis absorbance spectrum sufficiently narrow and intense for biosensing appli...
متن کاملNanometer scale alignment of block-copolymer domains by means of a scanning probe tip.
Alignment of perpendicularly oriented lamellar block copolymer domains using an AFM tip is demonstrated. The AFM tip orients the domains through local shearing, resulting in domain alignment parallel to tip travel. AFM tips can also deposit block copolymer nanostructures on heated substrates with a variety of experimentally observed domain alignments.
