In a Hydrogel, Microplasma-Synthesized Magnetic Nanoparticles

Recent years have seen expanded examination into the utilization of non‐equilibrium atmospheric pressure microplasma (APM) innovation in a wide scope of applications. Specifically, the communication among APM and liquids offers a hearty strategy for arrangement handling of nanomaterials because of the enriched chemical environment in the region of the plasma/liquid interface. The versatility of APM preparing has been shown by the wide assortment of nanomaterials synthesized effectively. Notwithstanding metal nanoparticles (NPs), APM handling has additionally been utilized in the synthesis and functionalization of different nanostructures, for example, Si nanocrystals, nanocarbon materials, and metal oxides in aqueous solutions. This demonstrates APM methods are viable routes to engineering and tailoring the surface/interfacial properties of nanomaterials and nanocomposites. While much research has investigated APM synthesis and processing of different nanomaterials in water, the incorporation of such nanomaterials into a polymeric matrix to form functional nanocomposites has gotten restricted consideration.

One territory of enthusiasm for the biomedical field is the advancement of multifunctional hydrogel‐based nanocomposites. Hydrogels are a class of polymers which are very crosslinked hydrophilic polymer networks comprising of >90% water by mass. Numerous hydrogels have fantastic biocompatibility and show a reaction to environmental stimuli, for example, temperature or potentially pH. These promising attributes have supported their wide use in applications, for example, drug delivery, cancer therapy, and tissue engineering. Further usefulness can be presented by incorporating utilitarian NPs with hydrogels to form a nanocomposite, and such frameworks have demonstrated intriguing properties for applications, for example, anti‐microbial, sensing, imaging, drug delivery, cancer therapeutics, and numerous others.

A magnetic thermo‐sensitive hydrogel joining APM-synthesized magnetic nanoparticles (MNPs) has been effectively accomplished. The magnetization of the magnetic hydrogel test indicates upgraded performance execution contrasted with MNPs synthesized straightforwardly in water. The resultant magnetic hydrogel framework was found to display a reversible phase change at temperatures of enthusiasm for biomedical applications.

Future work intends to characterize magnetic nanocomposites for practical applications, for example, magnetic resonance imaging, drug delivery, and hyperthermia applications. “The material produced in this study could be of interest in a range of applications, highlighting the potential of APM technology as a synthetic route for the fabrication of hydrogel nanocomposites in fields such as biomedical, environmental, microfluidics, and sensing”, according to team member Dan Sun.
