A novel occurrence of polymorphic self-assembled zinc oxide nanoparticles encapsulated by sodium alginate and pectin
Polymorphic nanoparticles are very appealing today as they can be used in various environments and healthcare applications. The encapsulation of sodium alginate and pectin resulted in polymorphic self-assembled zinc oxide nanoparticles. This study investigates the properties of polymorphic zinc oxide nanoparticles that self-assemble. As indicated by UV–vis spectroscopy, zinc oxide nanoparticles (ZnO NPs) exhibit peak absorption spectrums at 352 nm, sodium alginate nanoparticles encapsulated in sodium alginate (SA-ZnO NPs) exhibit 348 nm and 432 nm, and pectin nanoparticles encapsulated in zinc oxide nanoparticles (PET-ZnO NPs) exhibit 205 nm and 264 nm. We confirmed the crystal structures of ZnO nanoparticles, SA-ZnO nanoparticles, and PET-ZnO nanoparticles using X-ray diffraction (XRD). All these nanoparticles exhibited infrared stretching vibrations when subjected to Fourier transform infrared spectroscopy (FTIR). The spherical shape of ZnO nanoparticles, the cabbage-like morphology of SA-ZnO nanoparticles, and the flower-like morphology of PET-ZnO nanoparticles were all revealed by scanning electron microscopy (SEM). Using DLS, we found that nanoparticles ranged from 180 to 600 nm in size, indicating excellent stability in the zeta potential. A gradual weight loss was observed as the thermogravimetric analysis (TGA) of ZnO nanoparticles, SA-ZnO nanoparticles, and PET-ZnO nanoparticles varied in temperature. These findings might reveal insights into biofunctionalization, which could help in the delivery of targeted drugs and the development of biomedical applications. Research in this area will most likely advance nanoplatforms for biomedical applications, increasing treatment options and diagnostic capabilities.
期刊介绍:
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
