Selective extraction of phospholipids from food by-products by supercritical carbon dioxide and ethanol and formulating ability of extracts

Selective extraction of phospholipids (PLs) from camelina press cake and scallop by-products was investigated using Supercritical Fluid Extraction at 45 °C, 25 MPa, with (2–30%) ethanol (EtOH) as co-solvent. A two-step process consisting of a first extraction with CO2 +…

Selenium-Fortified Kombucha–Pollen Beverage by In Situ Biosynthesized Selenium Nanoparticles with High Biocompatibility and Antioxidant Activity

Biogenic selenium nanoparticles (SeNPs) have been shown to exhibit increased bioavailability. Fermentation of pollen by a symbiotic culture of bacteria and yeasts (SCOBY/Kombucha) leads to the release of pollen content and enhances the prebiotic and probiotic effects of Kombucha. The…

SERS tags derived from silver nanoparticles and aryl diazonium salts for cell Raman imaging

The surface functionalization of silver nanoparticles (NPs) by Raman reporters has stimulated a wide interest in recent years for the design of Surface-Enhanced Raman Spectroscopy (SERS) labels. However, silver NPs are prone to oxidation and aggregation, which strongly limits their…

SiO2-PVA-Fe(acac)3 Hybrid Based Superparamagnetic Nanocomposites for Nanomedicine: Morpho-textural Evaluation and In Vitro Cytotoxicity Assay

A facile sol-gel route has been applied to synthesize hybrid silica-PVA-iron oxide nanocomposite materials. A step-by-step calcination (processing temperatures up to 400 °C) was applied in order to oxidize the organics together with the iron precursor. Transmission electron microscopy, X-ray…

Soap-and metal-free polystyrene latex particles as a nanoplastic model

The ability of nanoplastics (NPTs) to bioaccumulate and cotransport pollutants in the whole organism is one of the most dangerous aspects of this form of plastic debris, defining a new class of emerging pollutants that is still largely unknown. In…
