The current study describes a simple method to fabricate soy protein-based nano-biocomposites (NBCs) impregnated with sago starch-capped copper oxide nanorods (CuO NRs), for electrochemical detection of cytosine, which is useful for de novo drug formulations in pharmaceutics. The physicochemical properties of the NBCs were studied in detail and might be useful for biomedical applications. CuO NRs of sizes of 18.1–22.7 nm were synthesized by varying the concentrations of sago starch (0.5–5 μM) and characterized using various analytical techniques. Sago starch acts as both a reducing agent and stabilizer. The NRs show better optical properties (increased band gap E g = 3.01 eV), which could find potential applications in the photovoltaic cells. The sago-capped CuO NRs were impregnated in soy protein (1:1 ratio), and the physicochemical properties of the fabricated nanobiocomposites (NBCs) were studied. Differential scanning calorimetry (DSC)/thermogravimetric analysis (TGA) was employed to determine the thermodynamic parameters, and the results indicate enhanced thermal stability of the NBCs. Moreover, increased water uptake of the NBCs demonstrates the biodegradability of the prepared NBCs that can find use in tissue engineering applications. This CuO-SG-SY/GCE can be used for the detection and quantification of cytosine in real-sample analysis. Thus, soy protein NBCs incorporated with sago starch-capped CuO NRs provide a simple and facile route, which is ecofriendly and cost-effective and has both industrial and pharmaceutical applications.

“…Recent studies have demonstrated the potential of plant essential oils (EOs) in combination with antibiotics against a range of pathogens, such as Escherichia coli ( E. coli ) , Staphylococcus aureus ( S. aureus ), and Bacillus subtilis . [ 2–7 ] The antibacterial action of these oils is believed to involve permeating the bacterial membrane and cytoplasm. [ 8–11 ] It has been observed that EOs are not likely to induce bacterial drug resistance, and can even produce a synergistic effect with antibiotics.…”

The extensive use and misuse of antibiotics have resulted in bacterial resistance becoming increasing commonplace. Essential oils (EOs) are known to possess antimicrobial properties and therefore have many potential practical applications. However, the default of hydrophobicity, chemical instability, and volatility limit scope of application. Encapsulation of EOs in colloidal delivery systems can mitigate these challenges and allow for greater efficacy. A homogenous nanoemulsion (HS15‐CE) containing a combination of eucalyptol (Euc) and cefradine (Cef) is developed to explore its synergistic effect on antibacterial activity and potentially reduce the amount of antibiotic required to treat bacterial infections. The HS15‐CE nanoemulsion displays a synergistic effect on the inhibition of Escherichia coli (E. coli) growth in vitro, significantly decreasing the minimum inhibitory concentration (MIC) by eight times. The ex vivo imaging reveals high accumulation concentrations and long retention in bladders. Moreover, the nanoemulsion alleviates the E. coli induced cystitis infection, as evidenced by decreased bacterial colonies in urine, reduced inflammatory cytokines, and increased expression of tight junctional protein ZO‐1. These findings suggest the potential of the HS15‐CE nanoemulsion in providing a synergistic effect for the treatment of bacterial urocystitis.
