Advances in top–down and bottom–up surface nanofabrication: Techniques, applications & future prospects

Facet‐Controlled Synthetic Strategy of Cu2O‐Based Crystals for Catalysis and Sensing

“…Recently, much effort is dedicated to a so‐called “top‐down” engineering approach that delicately modifies crystals to create more highly active sites by etching and crystal cut, for the purpose of improvement the physical and functional properties of crystals 43, 46, 51, 68, 149, 150, 151, 152, 153, 154. (In this section, the “top‐down” means crystal carving without phase transformation; while the “top‐down” in the next section refers to total phase transformation from Cu 2 O to various hollow structures.)…”

Silica Surface Features and Their Role in the Adsorption of Biomolecules: Computational Modeling and Experiments

“…729 Both fields should be explored in depth, among other reasons because of the importance of DNA in developing nano-devices within a bottom-up approach. 730 For instance, in a way similar to nanolithography, one could pattern ordered DNA to the desired positions on a substrate that includes hydrophilicity and covalent attachment as provided by silica surfaces. 731 On the other hand, cell membranes are the main "contact surfaces" between a living organism and a biomaterial and, as a perspective, we believe that understanding the process of membrane lipids adhesion is key to ultimately improve the design on biocompatible materials.…”

The interplay of different relaxation channels in the excited state dynamics of photoinitiators

“…Photoinduced radical polymerization is a method with increasing importance due to promising applications including photocuring [1] and lithography [2][3][4]. A critical process is thereby the photoinduced polymerization initiation by triplet photoinitiators.…”
