Two bottom-up techniques suitable for the formation of regular nanopatterns on different length scales are nanosphere lithography (NSL) and block copolymer (BCP) lithography. In this paper it is shown that NSL and BCP lithography can be combined to easily design hierarchically nanopatterned surfaces of different materials. Nanosphere lithography is used for the pre-patterning of surfaces with antidots, i.e. hexagonally arranged cylindrical holes in thin films of Au, Pt and TiO2 on SiO2, providing a periodic chemical and topographical contrast on the surface suitable for templating in subsequent BCP lithography. PS-b-PMMA BCP is used in the second self-assembly step to form hexagonally arranged nanopores with sub-20 nm diameter within the antidots upon microphase separation. To achieve this the microphase separation of BCP on planar surfaces is studied, too, and it is demonstrated for the first time that vertical BCP nanopores can be formed on TiO2, Au and Pt films without using any neutralization layers. To explain this the influence of surface energy, polarity and roughness on the microphase separation is investigated and discussed along with the wetting state of BCP on NSL-pre-patterned surfaces. The presented novel route for the creation of advanced hierarchical nanopatterns is easily applicable on large-area surfaces of different materials. This flexibility makes it suitable for a broad range of applications, from the morphological design of biocompatible surfaces for life science to complex pre-patterns for nanoparticle placement in semiconductor technology.}}, author = {{Brassat, Katharina and Kool, Daniel and Bürger, Julius and Lindner, Jörg}}, issn = {{2040-3364}}, journal = {{Nanoscale}}, number = {{21}}, pages = {{10005--10017}}, publisher = {{Royal Society of Chemistry (RSC)}}, title = {{{Hierarchical nanopores formed by block copolymer lithography on the surfaces of different materials pre-patterned by nanosphere lithography}}}, doi = {{10.1039/c8nr01397g}}, volume = {{10}}, year = {{2018}}, } @article{3923, abstract = {{Dodecyl amine edge functionalized few-layer graphene oxide quantum dots were synthesized in good yields.

The modified graphene oxide quantum dots showed excellent solubility in various organic solvents, including ethers, methanol, toluene, n-hexane, heptane, xylene, dichloromethane and toluene. The stability of a resulting toluene solution was also proven by static light scattering measurements over several days. The excellent solubility gives the possibility of an efficient and fast spray application of the functionalized graphene oxide quantum dots to steel surfaces. Hence, the macroscopic friction behavior was investigated with a Thwing-Albert FP-2250 friction tester. A thin film of the dodecyl amine functionalized graphene oxide quantum dots on steel lowered the friction coefficient from 0.17 to 0.11 and revealed a significant corrosion inhibition effect.}}, author = {{Wolk, Andreas and Rosenthal, Marta and Neuhaus, Stephan and Huber, Klaus and Brassat, Katharina and Lindner, Jörg and Grothe, Richard and Grundmeier, Guido and Bremser, Wolfgang and Wilhelm, René}}, issn = {{2045-2322}}, journal = {{Scientific Reports}}, number = {{1}}, publisher = {{Springer Nature}}, title = {{{A Novel Lubricant Based on Covalent Functionalized Graphene Oxide Quantum Dots}}}, doi = {{10.1038/s41598-018-24062-2}}, volume = {{8}}, year = {{2018}}, } @article{3925, abstract = {{Site-specific formation of nanoscaled protein structures is a challenging task. Most known structuring methods are either complex and hardly upscalable or do not apply to biological matter at all. The presented combination of enzyme mediated autodeposition and nanosphere lithography provides an easy-to-apply approach for the buildup of protein nanostructures over a large scale. The key factor is the tethering of enzyme to the support in designated areas. Those areas are provided via prepatterning of enzymatically active antidots with variable diameters. Enzymatically triggered protein addressing occurs exclusively at the intended areas and continues until the entire active area is coated. After this, the reaction self-terminates. The major advantage of the presented method lies in its easy applicability and upscalability. Large area structuring of entire support surfaces with features on the nanometer scale is performed efficiently and without the necessity of harsh conditions. These are valuable premises for large-scale applications with potentials in biosensor technology, nanoelectronics, and life sciences.}}, author = {{Rüdiger, Arne A. and Brassat, Katharina and Lindner, Jörg and Bremser, Wolfgang and Strube, Oliver I.}}, issn = {{0743-7463}}, journal = {{Langmuir}}, number = {{14}}, pages = {{4264--4270}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Easily Accessible Protein Nanostructures via Enzyme Mediated Addressing}}}, doi = {{10.1021/acs.langmuir.7b04089}}, volume = {{34}}, year = {{2018}}, } @inproceedings{3927, author = {{Grundmeier, Guido and Brassat, Katharina and Keller, A. and Lindner, Jörg}}, location = {{Warsaw, Poland}}, title = {{{With directed self-arrangement of DNA origami to large-area quantum dot arrays}}}, year = {{2018}}, } @inproceedings{3929, author = {{Brassat, Katharina and Kool, Daniel and Lindner, Jörg}}, location = {{Warsaw, Poland}}, title = {{{Hierarchical nanopore and nanoring arrays by self-assembly techniques}}}, year = {{2018}}, } @inproceedings{3930, author = {{Brassat, Katharina and Taube, A. and Kool, Daniel and Tasche, L. and Hoyer, K.P. and Schaper, Mirko and Lindner, Jörg}}, location = {{Warsaw, Poland}}, title = {{{Ti-6Al-4V alloy: 3D printing of lightweight implants and nanopatterning by self-assembly}}}, year = {{2018}}, } @inproceedings{3943, author = {{Brassat, Katharina and Kool, Daniel and Taube, A. and Schaper, Mirko and Lindner, Jörg}}, location = {{Straßburg, France}}, title = {{{Morphology investigation of nanopores by block copolymer lithography on different material surfaces}}}, year = {{2018}}, } @inproceedings{3944, author = {{Brassat, Katharina and Brüngeler, A. and Bremser, W. and Strube, O.I. and Lindner, Jörg}}, location = {{Straßburg, France}}, title = {{{Nanoscopic protein arrays on BCP prepatterned surfaces}}}, year = {{2018}}, } @inproceedings{3945, author = {{Brassat, Katharina and Ramakrishna, S. and Keller, A. and Lindner, Jörg}}, location = {{Phoenix (AZ), USA}}, title = {{{Hierarchical nanopatterns by site-selective DNA origami adsoprtion on pre-patterned surfaces}}}, year = {{2018}}, } @inproceedings{3946, author = {{Drude, Dennis and Lindner, Jörg}}, location = {{Phoenix (AZ), USA}}, title = {{{Simulation of Transport Processes during the Convective Self-Assembly of Colloidal Nanomasks}}}, year = {{2018}}, } @inproceedings{3947, author = {{Brassat, Katharina and Bremser, W. and Strube, O. and Grundmeier, G. and Keller, A. and Lindner, Jörg}}, location = {{Warsaw (Poland)}}, title = {{{Protein and DNA origami arrays on large areas by directed self-assembly }}}, year = {{2018}}, } @inproceedings{3948, author = {{Lindner, Jörg}}, location = {{TU Dortmund}}, title = {{{Selbstorganisation für die Nanotechnik von morgen}}}, year = {{2018}}, }
