“…1 With a significant amount of water in the network, hydrogels exist in a half liquid-like and a half solid-like state 2 and thereby possess high water storage capacity, elasticity, flexibility, and permeability. 3 The network structure in the hydrogels can be formed by either chemical cross-linking or physical cross-linking.…”

Clay mineral-containing nanocomposite hydrogels have been proven to have exceptional composition, properties, and applications, and consequently have attracted a significant amount of research effort over the past few years. The objective of this paper is to summarize and evaluate scientific advances in clay mineral-containing nanocomposite hydrogels in terms of their specific preparation, formation mechanisms, properties, and applications, and to identify the prevailing challenges and future directions in the field. The state-of-the-art of existing technologies and insights into the exfoliation of layered clay minerals, in particular montmorillonite and LAPONITE s , are discussed first. The formation and structural characteristics of polymer/clay nanocomposite hydrogels made from in situ free radical polymerization, supramolecular assembly, and freezing-thawing cycles are then examined. Studies indicate that additional hydrogen bonding, electrostatic interactions, coordination bonds, hydrophobic interaction, and even covalent bonds could occur between the clay mineral nanoplatelets and polymer chains, thereby leading to the formation of unique three-dimensional networks. Accordingly, the hydrogels exhibit exceptional optical and mechanical properties, swelling-deswelling behavior, and stimuli-responsiveness, reflecting the remarkable effects of clay minerals. With the pivotal roles of clay minerals in clay mineral-containing nanocomposite hydrogels, the nanocomposite hydrogels possess great potential as superabsorbents, drug vehicles, tissue scaffolds, wound dressing, and biosensors. Future studies should lay emphasis on the formation mechanisms with in-depth insights into interfacial interactions, the tactical functionalization of clay minerals and polymers for desired properties, and expanding of their applications.

“…The PT macroinitiator 3 is soluble in many organic solvents, such as tetrahydrofuran, dimethylformamide, chloroform, dichloromethane, and toluene, due to the presence of the bromoisobutyl initiator group at the 3-position. Formation of 3 was confirmed by 1 H NMR spectroscopy and gel permeation chromatography (GPC), the latter of which yielded M n = 1.09 10 5 and M w /M n = 2.95. [23] As expected owing to the FeCl 3 -mediated polymerization, 3 was found to be regioirregular, as evident in its 1 H NMR spectrum; the protons on the 3-alkyl chain adjacent to the thiophene ring (65 % head-to-tail coupling) give rise to a twocomponent signal at 3.24 ppm and 3.00 ppm.…”

Ungewöhnliche Bürsten: Aus einem Poly(thiophen)‐Rückgrat und aufgepfropften Poly(N‐isopropylacrylamid)‐Ketten bestehende Bürsten zeigen die bisher höchste Wasserlöslichkeit eines neutralen Poly(thiophens) sowie temperaturabhängige optische Eigenschaften und Wasserlöslichkeiten (siehe Bild). Der π‐π*‐Übergang des Poly(thiophen)‐Rückgrats im Pfropfpolymer verschiebt sich in der Nähe der Kollapstemperatur der Poly(N‐isopropylacrylamid)‐Ketten.

“…7,8 Recently, numerous new types of boronic acid sensors have been fabricated to detect blood glucose concentrations, [9][10][11][12][13] ionic compounds, [14][15][16][17] traces of water in solvents, 18,19 hydrogen peroxide (H 2 O 2 ), [20][21][22] catecholamines, 23 as well as using boronic acids as biochemical tools for various applications, including tumor cell imaging, 24,25 enzyme inhibitors 26 and cell delivery systems. 27 Therefore, the boron-based uorescent sensor is still hot in today's research.…”

Recent development of boronic acid-based fluorescent sensors

et al. 2018

As Lewis acids, boronic acids can bind with 1,2-or 1,3-diols in aqueous solution reversibly and covalently to form five or six cyclic esters, thus resulting in significant fluorescence changes. Based on this phenomenon, boronic acid compounds have been well developed as sensors to recognize carbohydrates or other substances. Several reviews in this area have been reported before, however, novel boronic acid-based fluorescent sensors have emerged in large numbers in recent years. This paper reviews new boronbased sensors from the last five years that can detect carbohydrates such as glucose, ribose and sialyl Lewis A/X, and other substances including catecholamines, reactive oxygen species, and ionic compounds. And emerging electrochemically related fluorescent sensors and functionalized boronic acid as new materials including nanoparticles, smart polymer gels, and quantum dots were also involved.By summarizing and discussing these newly developed sensors, we expect new inspiration in the design of boronic acid-based fluorescent sensors.
