“…These natural compounds-mediated procedures for synthesis of AuNPs represent advantages over conventional chemical and physical methods, as they are simply, low-cost, energy-efficient, and nontoxic green routes [11,12,13,14]. In this regard, we focused our attention on natural polysaccharide extracted from seaweed, which is a proven source of bioactive compounds [15]. Furthermore, natural polysaccharides can be used for AuNPs synthesis in a different way [16].…”

Gold nanoparticles (AuNPs) were synthesized using a facile solvothermal method with alginate sodium as both reductant and stabilizer. Formation of AuNPs was confirmed by UV-vis spectroscopic analysis. The synthesized AuNPs showed a localized surface plasmon resonance at approximately 520–560 nm. The AuNPs were characterized using transmission electron microscopy, X-ray diffraction and dynamic light scattering. Transmission electron microscopy revealed that the AuNPs were mostly nanometer-sized spherical particles. Powder X-ray diffraction analysis proved the formation of face-centered cubic structure of Au. Catalytic reduction of 4-nitrophenol was monitored via spectrophotometry using AuNPs as catalyst, and further a non-enzymatic sensor was fabricated. The results demonstrated that AuNPs presented excellent catalytic activity and provided a sensitive response to H2O2 detection.

“…Interestingly, presence of DAS did not influence the microstructure of the scaffolds as compared to non-cross-linked samples as shown by SEM. All the tested samples were found to be cytocompatible and supported adhesion and growth of MG-63 cells as shown by live-dead staining and metabolic activity test.Polymers 2020, 12, 372 2 of 13 are non-toxic, the biomaterial does not elicit an intensive immune response and its removal after tissue regeneration is not needed [9].A number of protein polymers (silk fibroin, collagen, gelatin) and polysaccharides (chitosan, carrageenan, chondroitin sulphate, sodium alginate, hyaluronic acid) are used in biomaterials production [10][11][12][13][14].Currently, polymer implants are most commonly manufactured with collagen [15][16][17]. Collagen is one of the most abundant proteins in the human body (one third of total proteins) and it is the main protein of the connective tissue.…”

In this study, three-dimensional (3D) biopolymeric scaffolds made from collagen, silk fibroin and chitosan were successfully prepared by the freeze drying method. Dialdehyde starch (DAS) was used as a cross-linking agent for the materials. The properties of the materials were studied using density and porosity measurements, scanning electron microscope (SEM) imaging, swelling and moisture content measurements. Additionally, cytocompatibility of the materials in contact with MG-63 osteoblast-like cells was tested by live/dead staining and resazurin reduction assay on days 1, 3 and 7. It was found that new 3D materials made from collagen/silk fibroin/chitosan binary or ternary mixtures are hydrophilic with a high swelling ability (swelling rate in the range of 1680–1900%). Cross-linking of such biopolymeric materials with DAS increased swelling rate up to about 2100%, reduced porosity from 96–97% to 91–93%, and also decreased density and moisture content of the materials. Interestingly, presence of DAS did not influence the microstructure of the scaffolds as compared to non-cross-linked samples as shown by SEM. All the tested samples were found to be cytocompatible and supported adhesion and growth of MG-63 cells as shown by live–dead staining and metabolic activity test.

“…There is now abundant research on the synthesis of polysaccharide-based nanostructures [12], much of it focused on the functionality of polysaccharides and/or the controlled release of natural ingredients. One clear example is starch, which can be nanostructured and functionalized with bioactive substances for targeted administration.…”

The Functionalization of Nanostructures and Their Potential Applications in Edible Coatings

et al. 2018

View full text Add to dashboard Cite

Nowadays, edible coatings incorporated with nanostructures as systems of controlled release of flavors, colorants and/or antioxidants and antimicrobial substances, also used for thermal and environmental protection of active compounds, represent a gap of opportunity to increase the shelf life of food highly perishable, as well as for the development of new products. These functionalized nanostructures have the benefit of incorporating natural substances obtained from the food industry that are rich in polyphenols, dietary fibers, and antimicrobial substances. In addition, the polymers employed on its preparation, such as polysaccharides, solid lipids and proteins that are low cost and developed through sustainable processes, are friendly to the environment. The objective of this review is to present the materials commonly used in the preparation of nanostructures, the main ingredients with which they can be functionalized and used in the preparation of edible coatings, as well as the advances that these structures have represented when used as controlled release systems, increasing the shelf life and promoting the development of new products that meet the characteristics of functionality for fresh foods ready to eat.
