Special Issue Information

Dear Colleagues,

Nanoscale surface engineering refers to the design of physical, morphological and interfacial properties of nanoparticles or 2D nanostructured surfaces for a particular application. The surface chemistry of nanomaterials impacts an assortment of specific physical properties, such as magnetism, optics, electronics, catalysis and toxicity. Ligands and other surface molecules often play a major role in nanoparticle growth, form and crystallinity, in addition to bring new features such as (bio)chemical functional moieties, new interactions with the surrounding medium and adjusting the hydrophilic/lipophilic balance. Complex nanoparticle morphologies such as stars, core-shell, patchy and Janus nanoparticles are possible thanks to surface chemistry. Mastering nanoparticle self-assembly requires a solid knowledge of the surface chemistry, as the surface heavily influences particle-particle and particle-substrate attractive/repulsive forces. Surface chemistry can be used to chemically stabilize nanoparticles for instance, in processes involving high temperature treatments, against (photo)oxidization, or to protect the material from corrosion. This Special Issue will include, but not be limited to, any kind of nanoscale surface modification strategies addressing critical issues in fields related to nanotechnologies such as biomaterials, nanomedicine, plasmonics, metamaterials, energy harvesting, nanoelectronics, spintronics, and smart materials, among others. Through this plethora of topics, this issue will illustrate the fundamental nature of surface chemistry to material functionality, tunability and longevity.

The wrapping of nanoparticles (NPs) by a membrane is a phenomenon of widespread and generic interest in biology, as well as in a variety of technological applications, such as drug delivery, clinical diagnostics, and biomedical imaging. However, the mechanisms of the interaction between the membrane and NPs are not well understood yet. In this paper, we have presented an analytic thermodynamic model to investigate the wrapping process of NPs by a cell membrane. It is found that the bending energy of the deformed membrane increases nonlinearly with increasing wrapping degree, which leads to a free energy barrier for the wrapping. On the basis of analysis results, the wrapping of NPs can be divided into three types, i.e., impossible wrapping, barrier wrapping, and free wrapping. Furthermore, a phase diagram for the wrapping of NPs has been constructed, which clarifies the interrelated effects of the size and the ligand density of NPs. We hope that this work can provide some help in understanding the physical mechanism of the wrapping of NPs. Full article

We investigated the possibility of tuning the local switching properties of memristive crystalline SrTiO 3 thin films by inserting nanoscale defect nucleation centers. For that purpose, we employed chemically-synthesized Au nanoparticles deposited on 0.5 wt%-Nb-doped SrTiO 3 single crystal substrates as a defect formation template for the subsequent growth of SrTiO 3 . We studied in detail the resulting microstructure and the local conducting and switching properties of the SrTiO 3 thin films. We revealed that the Au nanoparticles floated to the SrTiO 3 surface during growth, leaving behind a distorted thin film region in their vicinity. By employing conductive-tip atomic force microscopy, these distorted SrTiO 3 regions are identified as sites of preferential resistive switching. These findings can be attributed to the enhanced oxygen exchange reaction at the surface in these defective regions. Full article
