Aug 29, 2017 Magnetic nanoparticles also include the group of metallic nanoparticles and nanoalloys. Naturally, surface coatings of nanoparticles are an integral part of their synthesis [ 12 , 41 ]. Generally, the coating is designed to improve stability and solubility of nanoparticles, increase their biocompatibility, target-specificity, and to prevent ...

Dec 13, 2002 These silver and gold nanoparticles should find use in a variety of areas that include photonics, catalysis, and SERS-based sensing. This work and previous demonstrations from other groups (17–22) make it clear that chemical synthesis of metal nanoparticles with well-controlled shapes, sizes, and structures is a practical reality.

Jan 01, 2022 Background: Obesity is becoming a global epidemic and reversing the pathological processes underlying obesity and metabolic co-morbidities is challenging. Obesity induced chronic inflammation including brain inflammation is a hallmark of obesity via the gut-brain axis. The objective of this study was to develop garlic exosome-like nanoparticles (GaELNs) that …

Nov 14, 2021 Sequential centrifugation can be used to prepared endosomes. For example, neuronal endosomes were obtained through first lyzing neurons with 20 times of syringe aspiration in lysis buffer (250 mM sucrose, 50 mM Tris-HCl, pH 7.4, 5 mM MgCl2, 1mM EDTA, 1mM EGTA) along with protease inhibitor mixture and then going through sequential …

The impact of CeO 2 nanoparticles (NPs) on plant physiology and soil microcosm and the underlying mechanism remains unclear to date. This study investigates the effect of CeO 2 NPs on plant growth and soil microbial communities in both the rhizosphere of cucumber seedlings and the surrounding bulk soil, with CeCl 3 as a comparison to identify the contribution of the …
