“…One of the most prominent examples are chitosan based polyelectrolyte complexes which have been revealed to be applicable in drug delivery systems [12,13]. The film-forming ability and the anionic nature of furcellaran also make it possible to establish a binary polyelectrolyte complex with chitosan to obtain binary biopolymer films [14,15]. The properties of biopolymer films can be enriched by the addition of active ingredients, such as plant extracts [16], essential oils [17] and nanomaterials [18].…”

Surface coatings of materials by polysaccharide polymers are an acknowledged strategy to modulate interfacial biocompatibility. Polysaccharides from various algal species represent an attractive source of structurally diverse compounds that have found application in the biomedical field. Furcellaran obtained from the red algae Furcellaria lumbricalis is a potential candidate for biomedical applications due to its gelation properties and mechanical strength. In the present study, immobilization of furcellaran onto polyethylene terephthalate surfaces by a multistep approach was studied. In this approach, N-allylmethylamine was grafted onto a functionalized polyethylene terephthalate (PET) surface via air plasma treatment. Furcellaran, as a bioactive agent, was anchored on such substrates. Surface characteristics were measured by means of contact angle measurements, X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Subsequently, samples were subjected to selected cell interaction assays, such as antibacterial activity, anticoagulant activity, fibroblasts and stem cell cytocompatibility, to investigate the Furcellaran potential in biomedical applications. Based on these results, furcellaran-coated PET films showed significantly improved embryonic stem cell (ESC) proliferation compared to the initial untreated material.

“…The mixed solutions become more negatively charged as the amount of FUR was increased (from ζ = −23.87 and −22.32 to −27.79 mV), which could indicate that FUR and protein hydrolysates formed stable molecular complexes. The intense negative charge on the surface could have been caused by the occurrence of anionic FUR 57 . After adding ARF to the complex, the zeta potential did not change significantly in either group.…”

“…The intense negative charge on the surface could have been caused by the occurrence of anionic FUR. 57 After adding ARF to the complex, the zeta potential did not change significantly in either group. In an earlier paper, a shrimp (L. vanamei) lipid extract was encapsulated using a partially purified soy phosphatidylcholine having lower electronegative zeta potential (−42 mV).…”

BackgroundThe aim of the work was to develop a technology for using waste from prawn and shrimp processing as a source of active ingredients that could be used in the promotion of healthy foods. From fresh and freeze‐dried prawn and shrimp shells, protein hydrolysates (carotenoproteins) were obtained using two different enzymes, flovourzyme and protamex.ResultsThe obtained hydrolysates were characterized in terms of protein content, degree of hydrolysis, and antioxidant and antimicrobial activity. The hydrolysate with the best antioxidant properties (FRAP value of 2,933.33 μM TE; ORAC value of 115.58 μM TE) was selected and tested for its possible use as a component of functional foods. Molecular weight distribution (SDS‐Page), amino acid profile and free amino acids, the solubility of the hydrolysate in different pH ranges, as well as foaming ability, were determined. It was found that this hydrolysate was characterized by an amino acid profile with high nutritional value, flavour enhancement properties and excellent solubility in a wide pH range (from 97.06 to 100%). Afterward, the possibility of using carotenoproteins from prawn waste as a component of an emulsion with furcellaran and a lipid preparation of astaxanthin, taken from post‐hydrolysate production waste, was investigated. The obtained complexes were stable as proved by the measurement of ζ‐potential (ζ = ‐23.87 and ‐22.32 to ‐ 27.79 mV).ConclusionIt is possible to produce stable complexes of this hydrolysate with furcellaran and to emulsify a lipid preparation of astaxanthin, obtained from waste following production of the hydrolysate, in them.This article is protected by copyright.

“…Other characteristics of chitosan, which include viscosity, mechanical ability, adsorption on solids and biofunctional activity, depend on many other factors. These include the chitosan structure and degree of deacylation (affecting, among other things, viscosity—the unbranched and linear form with a high degree of deacylation shows better viscosity), crystallinity, degradation methods, ionization range and molecular weight [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. In addition to the properties typical of all polysaccharides, chitosan is characterized by a wide range of unique biological properties.…”

The aim of this study was to use a simple, low-cost and environmentally friendly synthesis method to design nanocomposites. For this purpose, carbon nanostructures were used to reinforce the chitosan/alginate bond in order to improve the mechanical, solubility, water absorption and barrier (protection against UV radiation) properties of the chitosan/alginate structure. Scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), ultraviolet and visible light absorption spectroscopy (UV-VIS) and color analysis were utilized, and the thickness and mechanical properties of the obtained films were determined. The tests that were carried out showed an equal distribution of nanostructures in the composite material and the absence of chemical interactions between nanoparticles and polymers. It was also proven that the enrichment of the polysaccharide composite with graphene oxide and carbon nanotubes positively affected its absorption, mechanical capabilities and color.
