Special Issue Information

Dear Colleagues,

Bio-based materials—proteins, polysaccharides, or lipids—have taken up an increasing share in the development of surface chemistry in recent years. This is related to the dramatic degradation of the natural environment under the influence of synthetic surfactants.

Therefore, we now look for a safe, readily biodegradable alternative to synthetic compounds.

Recently, various biopolymers have been used as natural surface-active substances (i.e., saponins) or stabilizers of manufactured dispersed systems (foams, emulsions, or liquid films). There are incorporated into solutions in the form of dissolved compounds or insoluble organic nano or microparticles.

Moreover, bio-based materials often have their own biological or medical properties. Therefore, their introduction to the surface layer may be an additional positive factor in creating such systems. In this way, layers with healing or preserving properties (e.g., food) can be generated.

Developing similar multi-component systems based on various bio-based materials and their derivatives requires a thorough study of all the interactions between the used components of the mixtures (electrokinetic or hydrogen bonds). In addition, it is important that we know the morphology of the created surface layers, the conformational arrangement of individual components in the layers, and the impact of possible external factors (pH, temperature, and others) on the stability of the created dispersed systems.

This Special Issue is dedicated to the fundamental and applied aspects involved in the introduction of bio-based materials into Surface Chemistry. The developments in this field must go beyond the traditionally studied areas to incorporate new suggestions for resolving challenges. New theoretical approaches, numerical simulations, and novel methods of stabilizing foams, emulsions, or thin films with bio-based materials are welcome.

Rapid industrial growth is associated with an increase in the production of environmentally harmful waste. A potential solution to significantly reduce pollution is to replace current synthetic materials with readily biodegradable plastics. Moreover, to meet the demands of technological advancements, it is essential to develop materials with unprecedented properties to enhance their functionality. Polysaccharide composites demonstrate significant potential in this regard. Polysaccharides possess exceptional film-forming abilities and are safe for human use, biodegradable, widely available, and easily modifiable. Unfortunately, polysaccharide-based films fall short of meeting all expectations. To address this issue, the current study focused on incorporating carbon quantum dots (CQDs), which are approximately 10 nm in size, into the structure of a starch/chitosan biocomposite at varying concentrations. This modification has improved the mechanical properties of the resulting nanocomposites. The inclusion of nanoparticles led to a slight reduction in solubility and an increase in the swelling degree. The optical characteristics of the obtained films were influenced by the presence of CQDs, and the fluorescence intensity of the nanocomposites changed due to the specific heavy metal ions and amino acids used. Consequently, these nanocomposites show great potential for detecting these compounds. Cellular viability assessments and comet assays confirm that the resulting nanocomposites do not exhibit any cytotoxic properties based on this specific analytic method. The tested nanocomposites with the addition of carbon quantum dots (NC/CD II and NC/CD III) were characterised by greater genotoxicity compared to the negative control. The positive control, the starch/chitosan composite alone, was also characterised by a greater induction of chromatin damage in mouse cells compared to a pure mouse blood sample. Full article
