“…It can also be described as reduction of the droplet by water evaporation during the sample preparation on copper-coated grid of TEM. Secondly, only the core of the micelles could be detected by TEM due to not enough chain density in the corona to make visible contrast to the background [20,28]. Therefore, it is very likely that the observed size of aggregates by DLS is larger than the expected from TEM.…”

“…The micelle consists of a more or less swollen core of the insoluble blocks, which is surrounded by a flexible fringe of soluble blocks. Such micelles are usually spherical with narrow size distribution and may change in their size distribution and shape under certain conditions [20,26]. In this study, we have investigated the micellization of block copolymer by two different methods.…”

“…Furthermore, the self-assembly of the biomolecule and block copolymer may also form redox-responsive micelles, which can exhibit redox-triggered response by the change in their shape or size. Xiao et al reported the synthesis of amphiphilic block copolymers with aldehyde and ferrocene containing hydrophobic block and explored their redox-responsive micellization behaviour [20].…”

Amphiphilic block copolymer PMAEFc-b-PMVAPBA was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. The hydrophobic and hydrophilic blocks of copolymers self-assembled into spherical micelles in aqueous solution. The redox behaviour of ferrocene was studied by using water-soluble (NH 4 ) 2 Ce(NO 3 ) 6 and NaHSO 3 as the oxidizing agent and reducing agent, respectively. The change in polarity and swelling of micelles increased the hydrodynamic diameter due to the oxidation of ferrocene, while glucose binding with boronic acid hydroxyls leads to unimers or smaller aggregates. TEM and DLS were used to investigate the redox-controlled behaviour of micelles. This redox-responsive behaviour would provide a prerequisite for detection/binding of biological analytes study and redox-controlled release of drug.

This manuscript presents a brief overview of recent advances in multistimuli-responsive supramolecular gels (MRSGs). The synthesis of MRSGs with faster and smarter responsive abilities to a variety of external stimuli, such as redox reagents, pH changes, ligands, and coupling reagents, is one key issue for the upgrade of current molecular motors, signal sensors, shape memory devices, drug delivery systems, display devices, and other devices. However, the design rules of MRSGs are still not well understood. The lack of information about the relationship between the spatial structure and gelation behavior of existing gelators means that the knowledge required to design new gelators by the addition of functional moieties to well-known gelators is lacking. Insights into the gelation pathway of known gelators may bring inspiration to researchers who want to exploit elegant designs and specific building blocks to obtain their own MRSGs with predictable stimuli-responsive abilities.

“…In 2007, Wooley et al [181], for the first time, reported the direct RAFT polymerization of an unprotected aldehyde-containing monomer (vinylbenzaldehyde, VBA). Xiao et al [169] reported the preparation of polyFVFC-co-polyEGMA, which could be quantitatively modified with 1.2 equivalents of O-benzylhydroxylamine at 25 • C. Furthermore, Fulton demonstrated the dynamic nature of the reaction between an aldehyde and n-acylhydrazone, and therefore, probed the potential of polyVBA as a platform Post-Polymerization modification of (co)polymers bearing ketone and aldehyde groups.…”
