Special Issue Information

Dear Colleagues,

There are many more varieties of nanomaterials being produced today than a decade ago by molecular modification and in much larger quantities, necessitating the development of more precise and reliable characterization techniques. However, such categorization might be inadequate at times. This is due to the inherent limitations of correctly characterizing the molecular-modified nanoscale materials compared to bulk materials, such as their tiny size and limited quantity in certain circumstances after laboratory-scale manufacturing. Furthermore, because of the interdisciplinary nature of nanoscience and nanotechnology, not every research group has easy access to a diverse variety of characterization capabilities. In reality, a more thorough characterization of molecular-modified nanomaterials is frequently required, necessitating a comprehensive strategy involving the use of complementary methods. In this context, the goal of this Special Issue is to describe the current understanding and information of the usage, advancements, benefits, and drawbacks of a wide range of experimental methodologies for the characterization of molecular-modified nanomaterials utilizing advanced spectroscopic techniques. Different spectroscopic techniques are categorized according to the concept/group of the technique, the information it may deliver, or the nanoparticles it is intended for. The methods' major spectroscopic properties and operating principles are also described in the Special Issue, with numerous instances of their application presented in a comparative style when possible in connection to the property researched in each case.

This Special Issue is primarily concerned with the evolution of:

  • Basic principles and significance of molecular modification in nanomaterials development: application, opportunities, and challenges;
  • Theoretical concepts, experimental parameters, and data analyses of various advanced and combinatorial spectroscopy techniques;
  • Simultaneous chemical characterization and morphological of inorganic molecular modification at a nanoscale resolution of nanomaterials;
  • Biomedical spectroscopy technique for nanostructures and biosystems characterization on the process associated with nano-bio-interactions and conjugations;
  • Confirmation on new functional nanomaterials by organic surface modification with advanced and in situ spectroscopy technique;
  • Molecular modification of plasmonic nanoparticles with a combination of spectroscopy and morphological characterization;
  • Spectroscopy analysis for the interface interaction-, distribution-, and aging-related properties by polymer/biopolymer macromolecules modified of nanomaterials;
  • Molecular structure, molecular interaction, and supramolecular assemblies on metallic modified nanomaterials by combinatorial spectroscopy techniques;
  • Chirality detection of inorganic modified nanomaterials and their enantioselective interaction with spectroscopy analysis.

The utilization of cellulose to its full potential is constrained by its recalcitrance to dissolution resulting from the rigidity of polymeric chains, high crystallinity, high molecular weight, and extensive intra- and intermolecular hydrogen bonding network. Therefore, pretreatment of cellulose is usually considered as a step that can help facilitate its dissolution. We investigated the use of microwave oxygen plasma as a pre-treatment strategy to enhance the dissolution of cotton fibers in aqueous NaOH/Urea solution, which is considered to be a greener solvent system compared to others. Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, and Powder X-ray Diffraction analyses revealed that plasma pretreatment of cotton cellulose leads to physicochemical changes of cotton fibers. Pretreatment of cotton cellulose with oxygen plasma for 20 and 40 min resulted in the reduction of the molecular weight of cellulose by 36% and 60% and crystallinity by 16% and 25%, respectively. This reduction in molecular weight and crystallinity led to a 34% and 68% increase in the dissolution of 1% (w/v) cotton cellulose in NaOH/Urea solvent system. Thus, treating cotton cellulose with microwave oxygen plasma alters its physicochemical properties and enhanced its dissolution. Full article
