This study develops a novel strategy, based on block copolymer self‐assembly in solution, for preparing two‐dimensional (2D) graphene‐based mesoporous nanohybrids with well‐defined large pores of tunable sizes, by employing polystyrene‐block‐poly(ethylene oxide) (PS‐b‐PEO) spherical micelles as the pore‐creating template. The resultant 2D nanohybrids possess a sandwich‐like structure with Fe2O3 nanoparticle‐embedded...
Super‐resolution fluorescence microscopy allows for unprecedented in situ visualization of biological structures, but its application to materials science has so far been comparatively limited. One of the main reasons is the lack of powerful dyes that allow for labeling and photoswitching in materials science systems. In this study it is shown that appropriate substitution of diarylethenes bearing...
Macroporous particles that combine the property features of spherical structures and porous materials are expected to find use over micro‐ and macroscopic length scales from miniaturized systems such as cell imaging, drug and gene delivery to industrial applications. However, the capacity for de novo design of such materials is still limited. Here, a spontaneous process to fabricate monodisperse multifunctional...
On the basis of DNA self‐assembly, a thermal responsive polymer polypropylene oxide (PPO) is evenly inserted into a rigid 3D DNA network for the study of single molecular self‐collapsing process. At low temperature, PPO is hydrophilic and dispersed uniformly in the network; when elevating temperature, PPO becomes hydrophobic but can only collapse on itself because of the fixation and separation of...
In article number 1801452, Leiming Guo, Michael Philippi, and Martin Steinhart use polymer monoliths with surfaces topographically patterned with regular arrays of macropores having diameters in the range of one micron as a template and stamp. Ordered corrugated metal films are obtained, and the nanocrystals can be deposited onto underlying substrates in the form of ordered arrays.
Polystyrene‐block‐poly(2‐vinylpyridine) (PS‐b‐P2VP) monoliths containing regular arrays of macropores (diameter ≈1.1 µm, depth ≈0.7 µm) at their surfaces are used to pattern substrates by patterning modes going beyond the functionality of classical solid elastomer stamps. In a first exemplary application, the macroporous PS‐b‐P2VP monoliths are employed as sacrificial templates for the deposition...
In article number 1802734, Yoan C. Simon and co‐workers review the fabrication and usefulness of glassy polymersomes. Capitalizing on their noteworthy impermeability, rigidity, versatile assembly behavior, and readily available shape transformation, many groups have embarked on an exciting scientific journey to generate unique vesicular constructs, which could one day serve as cell mimics.
Polymer vesicles, also known as polymersomes, have garnered a lot of interest even before the first report of their fabrication in the mid‐1990s. These capsules have found applications in areas such as drug delivery, diagnostics and cellular models, and are made via the self‐assembly of amphiphilic block copolymers, predominantly with soft, rubbery hydrophobic segments. Comparatively, and despite...
