In an attempt to reduce such decay induced by pathogenic causes, several studies investigated the effectiveness of nanoparticles (NPs) that play a vital role in saving food products, especially fruits. Current research delves into biogenic silver (using marine alga Turbinaria turbinata (Tt/Ag-NPs) and their characterization using FT-IR, TEM, EDS, zeta potential. Some fungi, which cause fruit spoilage, were isolated. We studied impact Tt/Ag-NPs protect against isolated fungi vitro, influence as coating tomato blue mold caused Penicillium italicum (OR770486) over 17 days storage time. Five treatments examined: T1, healthy fruits used positive control; T2, sprayed with Tt/Ag-NPs; T3, infected P. followed (pre-coating); T4, coated infection (post-coating); T5, negative control, italicum. The results displayed are crystalline, spherical shape, size ranges between 14.5 39.85 nm, charges. Different concentrations possessed antifungal activities Botrytis cinerea, Rhodotorula mucilaginosa, expansum, Alternaria alternate, Stemphylium vesicarium. After two tomatoes being italicum, 55% spoilage. delayed weight loss, increased titratable acidity (TA%), antioxidant%, polyphenol contents, decreased pH total soluble solids (TSSs). There no significant pre-coating post-coating except phenol contents pre-coating. A particular focus is placed on novel promising approach utilizing combat foodborne pathogens preserve commodities, spotlight application safeguarding from decay.

Exploring the Effects of Seaweed Synthesized Nanoparticles on Human Cancer Cell Lines

Biochemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 4, 2025

Seaweeds can be found in either marine or brackish water and have the potential to bioactive. are important ecological, biological, regenerative components of maritime environment. Because their high concentration polysaccharides phytochemicals, they sparked a lot interest domains cosmetics, biomass for fuels, as source material nanoparticle synthesis. Phytochemicals seaweeds aid conversion metal ions nanoparticles, which easily overcome tumor micro-environment barrier cause damage cancer cells. In addition, nanotechnology-based medicine has promising therapeutic effect treatment. Functionalized nanoparticles improve effects anticancer drugs while also delivering them site over time. Metal attention scientific community use biomedical nanotechnology. Drug-loaded were more hazardous cells than bare drugs.

Enhancing Strawberry Preservation: Efficacy of Chitosan-Whey Protein Composite Coatings with Selenium Nanoparticle

IOP Conference Series Earth and Environmental Science, Journal Year: 2025, Volume and Issue: 1487(1), P. 012156 - 012156

Published: April 1, 2025

Abstract To estimate the total number of Enterobacteriaceae and Staphylococcus in strawberry fruits coated with chitosan whey proteins supported by selenium nanoparticles, experiment was conducted laboratory Department Food Science, Faculty Agriculture, Tikrit University. The included following combinations membranes: control sample (T0), chitosan-coated (T1), (T2). Sample protein (T2) (T3) plus nanoparticles (T4) (Sample (T5) (T6)) stored at refrigerator temperature for 1, 7 14 days, results showed that spp. Increased were not edible films on day incubation period all treatments except nanoparticle-supported biofilms T4, T5, T6, increase numbers, intestinal bacteria, staphylococcus bacteria negligible due to effective role these particles against microorganisms, types decreased inhibitory effect addition nutrient depletion low pH did contain nanoparticles. obtained show importance using membranes prolonging preservation strawberries.
