Worm-like micelles have attracted great interest due to their anisotropic structures. However, the experimental conditions for obtaining worm-like micelles are very restricted, which usually causes seriously poor reproducibility. In this work, significantly enhanced accessibility of worm-like micelles is realized by in situ crosslinking polymerization-induced self-assembly (PISA). The reproducibility of worm-like micelles is greatly improved due to the significantly enlarged experimental windows of worm-like micelles in the morphology diagram. Moreover, the reliability of the methodology to enhance the accessibility of worm-like micelles has been demonstrated in various in situ crosslinking PISA systems. The greatly enhanced accessibility and reproducibility of worm-like micelles is undoubtedly cost-effective especially in scale-up production, which paves the way for further application of worm-like micelles with various compositions and functionalities.

Nano-formulated pesticides are increasingly desired to control the insect pest and plant disease with superior efficacy for guaranteeing the high yield and quality in crop production. However, the impact of nanocarrier morphology on pesticide resistance against rainwash, photolysis, and overall pesticide bioactivity remains unknown. In this work, a series of well-defined and morphology-controllable polymer nanocarriers for pesticide are fabricated through polymerization-induced self-assembly.

The aggregation properties of sugar-based surfactants with methyl groups at multiple positions on the linear alkyl chain are an understudied topic. Therefore, in this study, we performed a structural analysis of aggregates formed by two types of sugar-based nonionic surfactants with multibranched methyl chains, 3,7,11-trimethyldodecyl maltoside (CMal), as well as with a linear chain, dodecyl--d-maltoside (CMal), in aqueous solutions using rheological and small-angle X-ray scattering techniques. CMal showed an excellent performance in lowering surface tension (28.

We study the high-frequency, micro-mechanical response of suspensions composed of cardiac and skeletal muscle myosin by optical trapping interferometry. We observe that in low ionic strength solutions, upon the addition of magnesium adenosine triphosphate (MgATP), myosin suspensions radically change their micro-mechanics properties, generating a viscoelastic fluid characterized by a complex modulus similar to a suspension of worm-like micelles. This transduction of energy, from chemical to mechanical, may be related to the relaxed states of myosin, which regulate muscle contractility and can be involved in the etiology of many myopathies.

Protein-surfactant interactions have been an ongoing topic of interest for many decades. Applications involving complexes of proteins and surfactants are relevant in food, pharmaceuticals, hygiene, molecular characterization, and other fields. In this study, the interactions of polymerized whey proteins (PWP) and sodium dodecyl sulfate (SDS) at high concentrations are investigated.
