pH- and temperature-responsive supramolecular assemblies with highly adjustable viscoelasticity: a multi-stimuli binary system

Abstract

Stimuli-responsive materials are increasingly needed for the development of smart electronic, mechanical, and biological devices and systems relying on switchable, tunable, and adaptable properties.

“…Subsequently, 5 μL of the suspension and a staining solution (1% uranyl acetate) were individually deposited onto a 300-mesh copper grid for a duration of 45 s each. Following this, the grid was allowed to air-dry at room temperature over the course of a night prior to conducting TEM observation ( Lin et al, 2023 ; Mu et al, 2023 ). The freeze-dried nanoparticle powder was characterized using SEM (Tescan LYRA-3 Model GMH) under high-resolution mode at 93.3 k × .…”

A metastable small organic molecule for secure memory devices

“…As one of the recent themes in materials science, a lot of effort has been directed to the development of 'smart' materials, which change their properties in response to specific stimuli, such as light, pH, temperature, magnetism, and mechanical force. [1][2][3][4][5] These so-called stimuli-responsive materials represent an exciting and rapidly growing cadre of materials that support broad and various applications, including catalysis, tissue engineering, drug delivery, smart interfaces, and bio-separations among others. [6][7][8][9][10][11][12][13][14][15][16] As part of the family of electronic devices, organic electrical memory devices have attracted enormous attention.…”

A quadruple-stimuli responsive supramolecular hydrogel constructed from a poly(acrylic acid) derivative and β-cyclodextrin dimer

“…Host–guest supramolecular hydrogels responding to environmental stimuli such as light, 1 temperature, 2 redox agents 3 and pH 4 have the potential to be used in controlled drug release, 5,6 artificial muscles and actuators, 7,8 self-healing, 9,10 shape-memory materials, 11,12 etc. To the best of our knowledge, supramolecular hydrogels that respond to three or more stimuli simultaneously are of great importance because they can generate more flexibility for complex environmental stimuli and have a wider range of applications with the coordination of different stimuli.…”
