[J. Phys. Chem. C] Real-Time in Situ Investigation of Supramolecular Shape Memory Process by Fluorescence Switching
Shape memory hydrogels (SMHs) that take advantage of supramolecular chemistry cross-links to fix temporary shapes at room temperature are newly developed important shape memory polymers. It is thus highly desirable to explore in detail the in situ formation and real-time spatial distribution of temporary supramolecular cross-links in SMH systems, which can provide more in-depth information about t...

[Chem. Eur. J.]Triple Noncovalent-Interaction-Containing Supramolecular Polymer Vesicle Chemosensors with Dynamically Tunable Detection Ranges
Chemosensors (CSs) with dynamically tunable detection ranges have important significance for their expansion in practical applications; however, most CSs possess an unchangeable detection limit. In this work, we report the first example of a supramolecular polymer vesicle (SPV) chemosensor with a dynamically tunable detection range. SPVs containing porphyrin (PP) moieties and β-cyclodextrin (β...

[J. Mater. Chem. B] Self-Assembled Proteinaceous Wound Dressings Attenuate Secondary Trauma and Improve Wound Healing In Vivo
A new type of wound dressing that can be easily peeled from the wound during frequent changes is essential in clinical application to reduce secondary trauma and relieve the pain patients suffered. Here, we discover that the phase-transitioned lysozyme nanofilm (PTLF) composing of self-assembled protein nanoparticles with amyloid-like structure inside can disassemble and detach from a substrate ...

[J. Mater. Chem. B] Regenerable smart antibacterial surfaces: full removal of killed bacteria via a sequential degradable layer
Conventional antibacterial surfaces are becoming less effective due to the emergence of multidrug resistant bacteria; in addition, difficulties related to the accumulation of killed bacteria are generally encountered. To circumvent these problems, in the present work, an antibiotic-free and regenerable antibacterial hybrid film with both photothermal bactericidal activity and bacteria-releasing ...

[J. Polym. Sci., Part A: Polym. Chem.] Thermoresponsive polymeric nanoparticles based on poly(2‐oxazoline)s and tannic acid
Hydrogen bonding is widely present and plays a significant role in material science and supramolecular chemistry. This work reports a straightforward strategy for the preparation
of polymeric nanoparticles from neutral poly(2-oxazoline)s (POx) and tannic acid (TA) driven by their intermolecular hydrogen bonding. Dynamic light scattering (DLS) and scanning electron microscope (SEM) measurement...

【[J. Mater. Chem. C]】Network Cracks-based Wearable Strain Sensors for both Subtle and Large Strain Detection of Human Motions
As an imitation of human skin’s
tactile sensing ability, flexible and stretchable strain sensors are highly
desirable because of their various applications in health monitoring, robotics,
human-machine interfaces. However, it is still a big challenge to fabricate
strain sensors with both high sensitivity and broad sensing range. Here we
report a simple, low cost and scalable fabrication strategy ...

【[Chem. Mater]】Light-Controlled Shrinkage of Large-Area Gold Nanoparticles Monolayer Film for Tunable SERS Activity
The two-dimensional (2D) monolayer gold nanoparticle (Au NP) film is of significant interest and importance in both fundamental and practical applications including optoelectronic devices, sensing, catalysis, and surface-enhanced Raman spectroscopy (SERS). Because of the weak physical interaction, the conventional monolayer Au NP film fabricated at the oil–water interface was unstable, easily bre...

【[Chem. Commun]】Actuating and memorizing bilayer hydrogels for a self-deformed shape memory function
A general strategy for fabricating a double layer self-deformed shape memory hydrogel which includes a thermo-responsive actuating layer and a pH-responsive memorizing layer is presented. Compared with traditional shape memory polymer systems, the temporary shape of the hydrogel could be generated by a thermo-responsive actuating layer upon the trigger of heat without the need for an external forc...
