The study reports the efficacy of nanofabricated citronellal inside the chitosan biopolymer (NeCn) against Aspergillus flavus growth, aflatoxin B (AFB) production, and active ingredient biodeterioration (Piperine) in Piper longum L. The prepared NeCn was characterized by Scanning Electron Microscopy (SEM), Dynamic Light Scattering (DLS), and Fourier Transform Infrared Spectroscopy (FTIR). The results revealed that the NeCn exhibited distantly improved antifungal (1.25 μL/mL) and AFB inhibition (1.0 μL/mL) compared to free Cn. The perturbances in membrane function, mitochondrial membrane potential, antioxidant defense system, and regulatory genes (Ver-1 and Nor-1) of AFB biosynthesis were reported as probable modes of action of NeCn. The NeCn (1.25 μL/mL) effectively protects the P. longum from A. flavus (78.8%), AFB contamination (100%), and deterioration of Piperine (62.39%), thus demonstrating its potential as a promising novel antifungal agent for food preservation.

This study introduces an innovative bio-based sorbent bead crafted by integrating chitosan (CS) biopolymers, Fe(NO3)3 and polydopamine nanoparticles (PDA NPs) via glutaraldehyde crosslinking. The primary focus of this study was the concurrent separation of diverse tetracycline antibiotics (TCs), followed by rigorous reversed-phase liquid chromatography analysis. The fabricated CS/Fe@PDA sorbent beads were comprehensively characterized using scanning electron microscopy and energy-dispersive X-ray spectroscopy, revealing a surface rich in active carbon (C), nitrogen (N), and oxygen (O) moieties.

The negative impact of repeated-mild traumatic brain injury (rmTBI) is profoundly seen in circadian-disrupted individuals. The unrelenting inflammation, glial activation, and gut dysbiosis are key neuropathological aberrations in the aftermath of rmTBI. In this study, we examined the impact of chitosan lactate (CL) on circadian disturbance (CD) + rmTBI-generated neurological dysfunctions and its prebiotic response on the gut-brain axis.

There is an increasing demand for a suitable bone substitute to replace current clinical gold standard autografts or allografts. Majority of previous studies have focused on the early effects of substitutes on bone formation, while information on their long-term efficacies remains limited. This study investigated the efficacies of natural hydroxyapatite (nHA) derived from oyster shells and synthetic hydroxyapatite mixed with collagen (COL/HA) or chitosan (CS/HA) on bone regeneration and implant fixation in sheep.

This study investigated the antioxidant and antimicrobial properties, as well as the volatile compounds, of Lactobacillus bulgaricus (L. bulgaricus) postbiotics (at concentration of 150 and 300 mg/L) and their combination with chitosan coatings (0.5% and 1%) on sausage quality (with 100 ppm nitrite) during 40 days of cold storage.

Marine and terrestrial organisms often utilise EGF/EGF-like domains in wet adhesives, yet their roles in adhesion remain unclear. Here, we investigate the Barbatia virescense byssal system and uncover an oxidation-independent, reversible, and robust adhesion mechanism where EGF/EGF-like domain tandem repetitions in adhesive proteins bind robustly to GlcNAc-based biopolymer. EGF/EGF-like-domain-containing proteins demonstrate over three-fold superior underwater adhesion to chitosan compared to the well-known strongest wet-adhesive proteins, mefp-5, and suckerin, when adhering to mica in an surface forces apparatus-based measurement.
