Special Issue Information

Dear Colleagues,

Multifunctional nanomaterials have become an increasingly popular field of research over the past few decades due to the significant changes in physical and/or chemical properties that occur at this small scale. Specifically, it has been seen that interesting modifications take place in magnetic, electronic, optical, and catalytic properties, among others, with respect to materials of larger dimensions. Accordingly, nanomaterials are used in a variety of applications, including catalysis, gas storage, spin crossover, sensors, magnetics, optics, and drug delivery.

This Special Issue of Nanomaterials will present recent innovative scientific works, collected from both academia and industry, that describe the state of the art of nanomaterials with multifunctional properties. Moreover, it is expected to present an overview of different methods used for the preparation and characterization of nanomaterials for potential applications.

The readers will find relevant information regarding some of the following topics:

  • Synthesis of multifunctional nanomaterials;
  • Organic/inorganic multifunctional nanocomposites;
  • New characterization techniques for functional nanomaterials;
  • Theoretical studies and modeling;
  • Nanocomposites and their applications;
  • Stimuli-responsive nanosystems;
  • Catalysis;
  • Bionanomaterials.

Finally, we would like to invite you to submit your manuscript to this Special Issue by sending a communication or a full paper from your group or a review article on some of these topics. We are looking forward to receiving your contributions.

Degradable Spirocyclic Polyacetal-Based Core-Amphiphilic Assemblies for Encapsulation and Release of Hydrophobic Cargo
Nanomaterials 2021, 11(1), 161; https://doi.org/10.3390/nano11010161 - 10 Jan 2021

Polymeric nanomaterials that degrade in acidic environments have gained considerable attention in nanomedicine for intracellular drug delivery and cancer therapy. Among various acid-degradable linkages, spirocyclic acetals have rarely been used to fabricate such vehicles. In addition to acid sensitivity, they benefit from conformational rigidity that is otherwise not attainable by their non-spirocyclic analogs. Herein, amphiphilic spirocyclic polyacetals are synthesized by Cu-catalyzed alkyne–azide “click” polymerization. Unlike conventional block copolymers, which often form core–shell structures, these polymers self-assemble to form core amphiphilic assemblies capable of encapsulating Nile red as a hydrophobic model drug. In vitro experiments show that while release from these materials can occur at neutral pH with preservation of their integrity, acidic pH accelerates efficient cargo release and leads to the complete degradation of assemblies. Moreover, cellular assays reveal that these materials are fully cytocompatible, interact with the plasma membrane, and can be internalized by cells, rendering them as potential candidates for cancer therapy and/or drug delivery.

pH-Dependent Formation of Oriented Zinc Oxide Nanostructures in the Presence of Tannic Acid

To crucially comprehend the relaying factors behind the growth mechanism of ZnO nanostructures, the needs to understand the cause of preferences in the enhancement of desired physicochemical properties are essential. The particular oriented attachment (OA) is believed to become the cause of the classical growth pattern of ZnO nanostructures which is mainly controlled by the Ostwald ripening (OR) process. In the present work, the concerns over the systematic changes in size and the morphological surface of ZnO nanostructures upon exposure to tannic acid (TA) prepared by drop-wise method turns the particles to different surface adjustment state. Here, we assessed the TA capping ability and its tendency to influence the OA process of the ZnO nanostructures. The detailed process of the growth-based TA system via transmission electron microscopy (TEM), scanning electron microscopy (SEM), and FFT autocorrelation revealed the pH effect on their physical properties which proved the transition surface properties state of the particles from rough to smooth states due to oriented attachment. For pure ZnO nanostructures, the surface is almost smooth owing to the strong bonding particles which are then changed to coarsened surface structures upon the introduction of TA. Strong surface adsorption of Zn cations and phenol ligands mediated the agglomerated nanocrystals, surprisingly with smaller nanostructures dimension. Full article
