Special Issue Information

Dear Colleagues,

This Special Issue of Nanomaterials on “Advances in Stimuli-Responsive Nanomaterials” aims to capture the latest research in the field of smart nanomaterials. The publications in the previous Special Issue involved a broad range of nanomaterials that can react or respond to external stimuli including metallic nanomaterials, oxides nanoparticles, 2D nanomaterials, inorganic heterogenous nanostructures, and polymer-based nanocomposites. Additionally, it covered their applications in microwave/terahertz-wave absorbers and devices, optical devices, micro- and nanomotors, sensors, catalysis, energy storage, and antimicrobial agents.

We thank all the authors for their contributions and reviewers for their assistance with this Special Issue. To continually stimulate more achievements in this field and highlight the importance of stimuli-responsive nanomaterials in such an exciting field, it is our pleasure to launch a follow-up Special Issue entitled “Advances in Stimuli-Responsive Nanomaterials II”. The main topic of this new-Special Issue is the same as the previous one, focusing on the research and development of smart stimuli-responsive nanomaterials and functional devices. It welcomes both theoretical and experimental approaches, covering aspects from the design and synthesis of novel nanomaterials or nanocomposites with stimuli-responsive properties, characterization, and analysis of the working principle and regulating mechanism of stimuli-responsive activities or performances and the development of new smart devices based on stimuli-responsive nanomaterials. Both reviews and original research articles are welcome.

Serotonin-based nanomaterials have been positioned as promising contenders for constructing multifunctional biomedical nanoplatforms due to notable biocompatibility, advantageous charge properties, and chemical adaptability. The elaborately designed structure and morphology are significant for their applications as functional carriers. In this study, we fabricated anisotropic bowl-like mesoporous polyserotonin (PST) nanoparticles with a diameter of approximately 170 nm through nano-emulsion polymerization, employing P123/F127 as a dual-soft template and 1,3,5-trimethylbenzene (TMB) as both pore expander and emulsion template. Their formation can be attributed to the synchronized assembly of P123/F127/TMB, along with the concurrent manifestation of anisotropic nucleation and growth on the TMB emulsion droplet surface. Meanwhile, the morphology of PST nanoparticles can be regulated from sphere- to bowl-like, with a particle size distribution ranging from 432 nm to 100 nm, experiencing a transformation from a dendritic, cylindrical open mesoporous structure to an approximately non-porous structure by altering the reaction parameters. The well-defined mesopores, intrinsic asymmetry, and pH-dependent charge reversal characteristics enable the as-prepared mesoporous bowl-like PST nanoparticles’ potential for constructing responsive biomedical nanomotors through incorporating some catalytic functional materials, 3.5 nm CeO2 nanoenzymes, as a demonstration. The constructed nanomotors demonstrate remarkable autonomous movement capabilities under physiological H2O2 concentrations, even at an extremely low concentration of 0.05 mM, showcasing the 51.58 body length/s velocity. Furthermore, they can also respond to physiological pH values ranging from 4.4 to 7.4, exhibiting reduced mobility with increasing pH. This charge reversal-based responsive nanomotor design utilizing PST nanoparticles holds great promise for advancing the application of nanomotors within complex biological systems. Full article
