“…At the structural level these terms are used to describe whether the nanoparticles show a tendency to cluster because of weak physical interactions that can be reversed in biological preparations or by strong forces where the clustering is practically irreversible. 17 Reversible clustering and "selfassembly" can be controlled thermally, 18 chemically, 19 or by light. 20 The concept of reversibility can also be extended to the description of how different nanoparticles bind to biological substrates.…”

Stroke is a leading cause of death and disability worldwide. The classification of stroke subtypes is difficult but critical for the prediction of clinical course and patient management, and limited treatment options are available. There is an urgent need for improvements in both diagnosis and therapy. Strokes have rapidly evolving phases of damage involving unique compartments of the brain, which imposes severe limitations for current diagnostic and treatment procedures. The rapid development of nanotechnology in other areas of modern medicine has ignited a widespread interest in its potential for the field of stroke. An important feature of nanoparticles is the relative ease in which their structures and surface chemistries can be modified for specific and potentially multiple, simultaneous purposes. Nanoparticles can be synthesized to carry and deliver therapeutics to specific cellular or subcellular compartments; they can be engineered to provide enhanced contrast for imaging based on the detection of changes in the blood flow; or possess ligand-specific chemistries which can facilitate diagnosis and monitor the treatment response. More specifically for a stroke, nanoparticles can be engineered to release their payload in response to the distinct extracellular processes occurring around the clot and in the ischemic penumbra, as well as aid in the detection of pathological hallmarks present at various stages of stroke progression. These capacities allow targeted release of disease-modifying agents in the affected brain tissue, increasing treatment efficacy, and limiting unwanted side effects. While nanospheres, liposomes, and mesoporous nanostructures all emerge as future prospects for stroke treatment and diagnosis, much of this potential is yet to be clinically realized. This review outlines aspects of nanotechnology identified as having potential to revolutionize the field of stroke.

“…In recent years, stimuli-responsive structural colors have been paid much attention. [21][22][23][24][25][26][27][28][29][30][31][32] Inspired by the ability to change the skin color during male contests or courtship of panther chameleons, some strategies have been developed to adjust the periodic structures aer their preparation. Yang et al prepared photonic crystals in shape memory polymers (SMPs) by selfassembling silica particles in a polymer matrix and the subsequent removal of silica colloids by wet etching.…”

Developing of novel carbon‐based materials for electrocatalytic oxygen reduction reaction is highly important for sustainable energy conversion. In this work, iron‐containing ionogels were prepared from functional ionic liquid 1‐propionic acid‐2‐methyl imidazole bromide as the linker and an organically‐modified silica framework as the host, which were polymerized in the presence of iron(III) nitrate nonahydrate. The ionogels are mechanically stable, yellowish and transparent. After pyrolysis and washing by acid, unique mesoporous carbon materials were innovatively synthesized. Moreover, the as‐obtained carbon materials possess very high surface areas (1127 m2 g−1), significant mesoporosity and abundant catalytic sites (e. g., effective N configurations). The optimal catalyst exhibits remarkable ORR activity with an onset potential (Eonset) of 0.98 V vs. RHE, a half‐wave potential (E1/2) of 0.823 V vs. RHE and a diffusion‐limited current density (jL) of 5.75 mA cm−2 in 0.1 M KOH, comparable to the commercial Pt/C catalyst in the same condition. This work provided a new strategy to fabricate promising electrocatalyts for application in fuel cells.
