Special Issue Information

Dear Colleagues,

This Special Issue is aiming to communicate new insights and recent scientific advances in the field of Functional Coatings and Soft Matter. The rapid development of nanotechnology and novel nanomaterials is of vital importance for advancing industrial solutions and meeting needs in our society. Functional and smart coating technology is among the most promising, most rapidly developing and most valuable strategies for offering well-defined and predesigned surface properties for various advanced applications. Numerous surface properties such as corrosion protection, barrier protection, wetting, self-cleaning, antimicrobial and antiviral properties, stiffness, wear, lubrication, conductivity and many more can be tailored and customized at the nanoscale. There are many novel coatings and soft matter solutions proposed, and these are of large scientific interest. In addition, there are rapid ongoing developments of various surface-sensitive characterization techniques. This sets the scene for this Special Issue to provide a platform to unite new nanoscale findings with the development of novel functional coatings and soft matter materials. In specific focus are new findings in nanomechanics, tribology and triboelectricity providing fundamental nanoscale information. Nanomechanics, for instance, probed by means of advanced atomic force microscopy methods, offers essential information for developments in a wide range of applications, from anti-corrosion barrier coatings to nanowearable electronics. New developments in the characterization of coatings and soft matter are also of high interest for this issue.

In particular, the topics of interest include, but are not limited to:

  • The nanomechanics of coatings and soft matter;
  • Tailoring the surface properties of coatings and soft matter (including self-assembled layers and biobased materials);
  • Nanoscale surface characterization, including the anticorrosion, barrier protection, local electrical, and antimicrobial properties of functional/smart coatings and soft matter;
  • The nanoscale characterization of the tribological and triboelectrical properties of coatings and nanocomposites;
  • New developments for probing the nanoscale properties of coatings and soft matter.

The present work introduces coordinative binding of CuII ions with both amino-functionalized silica nanoparticles (SNs) and green-emitting carbon dots (CDs) as the pregrequisite for the CuII-assisted self-assembly of the CDs at the surface of the SNs. The produced composite SNs exhibit stable in time stimuli-responsive green fluorescence derived from the CuII-assisted assemblage of CDs. The fluorescence response of the composite SNs is sensitive to the complex formation with glutathione (GSH), enabling them to detect it with the lower limit of detection of 0.15 μM. The spin-trap-facilitated electron spin resonance technique indicated that the composite SNs are capable of self-boosting generation of ROS due to CuII→CuI reduction by carbon in low oxidation states as a part of the CDs. The intensity of the ESR signals is enhanced under the heating to 38 °C. The intensity is suppressed at the GSH concentration of 0.35 mM but is enhanced at 1.0 mM of glutathione, while it is suppressed once more at the highest intracellular concentration level of GSH (10 mM). These tendencies reveal the concentrations optimal for the scavenger or reductive potential of GSH. Flow cytometry and fluorescence and confocal microscopy methods revealed efficient cell internalization of SNs-NH2-CuII-CDs comparable with that of “free” CDs. Full article
