Green synthesis of strontium nanoparticles self‐assembled in the presence of carboxymethyl cellulose: an in vivo imaging study

Abstract

Carboxymethyl cellulose (CMC) is one of the main derivatives of cellulose and is used as a drug carrier for hydrophobic and hydrophilic drugs, imaging in vivo, and biological applications. Encapsulation is a technology in which target compounds are coated with wall compounds to form microcapsules. This study reports a new chemical processing wet method for precipitation and encapsulation of strontium nanoparticles (Sr NPs) within CMC structures using a sonochemical method. Preparation parameters such as microwave power and irradiation time as well as morphology and particle size of Sr NPs were also investigated. Products were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis and atomic force microscopy. In this study, CMC was used as a biological stabilizer in a retentive phase to encapsulate Sr NPs. For the first time, Sr NPs were synthesized using CMC in a cost-effective, simple, fast, micellation-assisted, ultrasound method. Sr NPs were encapsulated in green capping agent structures of either 1%, 2% or 3% weight to provide an efficient optical nanostructure with a high yield at wavelengths 200-700 nm for use in in vivo imaging studies.

Biosynthesis of Strontium Nanoparticles Using Mimosa pudica and its Antioxidant Effect

“…[ 7 ] Because of its radioisotopes, strontium has potential applications in cancer therapy and imaging (Fekri et al, 2019). [ 8 ] The potential of Mimosa pudica as a natural source for the production of strontium nanoparticles with antioxidant activity, which could find uses in a variety of disciplines like medicine and biotechnology, is highlighted by this study’s findings in its entirety.…”

Dexamethasone: Insights into Pharmacological Aspects, Therapeutic Mechanisms, and Delivery Systems

“…Polymeric NPs represent additional drug delivery systems with a vast potential for targeted and localized delivery of drugs/genes. − Natural polymers such as chitosan, arginine, dextrin, poly­(glycolic acid), polysaccharides, poly­(lactic acid), and hyaluronic acid have been used for developing polymeric drug delivery systems . Some synthetic polymers, including poly­(2-hydroxyethyl methacrylate), poly­(ethylenimine)­s, poly­( N -isopropylacrylamide)­s, and dendritic polymers, have also been used for polymeric-based NPs’ development .…”

Nanomaterials in Bone Regeneration

“…Sr-NPs were applied successfully as an efficient agent for in vivo imaging after injection into the neck area and the peritoneum of male BALB/c mice. The use of Sr-NPs is a good alternative to eliminate toxic and carcinogenic compounds in in vivo imaging [178].…”
