Comparative analysis of anti-solvent and emulsification techniques for the synthesis of quercetin-epigallocatechin gallate nanowires: Characterization and biomedical applications
The current study was based on the idea of accomplishing the advantages of two polyphenols, quercetin (QT) and Epigallocatechin Gallate (EGCG), by synthesizing a nano-combination model using two different methods: emulsification (Mix1) and the anti-solvent method (Mix2). Morphological studies of QT, EGCG, Mix1, and Mix2 were performed using transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), Brunauer-Emmett- Teller (BET) surface area analysis, and Fourier-transform infrared spectroscopy (FTIR). Antimicrobial efficacy and Minimum Inhibitory Concentration (MIC) were tested against Salmonella typhi and nine other human pathogens. Antioxidant activity was also evaluated. The results showed the formation of nanowires using both methods. Mix1 exhibited agglomerated and adhered particles, whereas Mix2 exhibited rougher morphology. Maximum absorbance for both Mix1 and Mix2 was observed at 374 nm. FT-IR analysis confirmed that QT and EGCG were physically attracted to each other. Mix1 and Mix2 exhibit enhanced synergistic antimicrobial and antioxidant properties compared with the original polyphenols, which may enhance their bioavailability.
期刊介绍:
Process Biochemistry is an application-orientated research journal devoted to reporting advances with originality and novelty, in the science and technology of the processes involving bioactive molecules and living organisms. These processes concern the production of useful metabolites or materials, or the removal of toxic compounds using tools and methods of current biology and engineering. Its main areas of interest include novel bioprocesses and enabling technologies (such as nanobiotechnology, tissue engineering, directed evolution, metabolic engineering, systems biology, and synthetic biology) applicable in food (nutraceutical), healthcare (medical, pharmaceutical, cosmetic), energy (biofuels), environmental, and biorefinery industries and their underlying biological and engineering principles.
