Structural analysis by X-ray diffraction confirms cubic unit cell structure of CTS nano-spheres. The energy-dispersive X-ray analysis showed CTS nano-spheres to be copper-rich and tin-deficient.

The antibacterial activity shows 100% activity index with higher zone of inhibition in <i>Listeria monocytogenes</i> and <i>Staphylococcus aureus.</i> The antioxidant activity of CTS nano-spheres determined using the DPPH assay showed IC<sub>50</sub> value of 61.60 µg/ml stating moderate antioxidant efficiency. The in vitro cytotoxic analysis is carried out by employing A549 lung cancer cell lines. The in vivo and vitro cytotoxic analysis provided the potent cytotoxicity of CTS nano-spheres, as reflected in LC<sub>50</sub> value of 40.40 µg/ml and IC<sub>50</sub> value of 57.75 ± 2.34 μg/ml. The mechanistic evolution of CTS nano-spheres for their antibacterial activity is proposed in this work. The leaching behaviour of CTS nano-spheres revealed higher leaching of Sn<sup>4+</sup> ions than Cu<sup>+</sup> ions, contributing to their strong antibacterial activity. The zeta potential of CTS nano-spheres is found to be − 30.70 mV, which showed less agglomeration of CTS nano-spheres, depicting an efficient antibacterial activity.

The biosensor utilizes magnetic nanocomplexes, synthesized through three distinct methods, each varying the attachment sequence of the spike protein and aminoferrocene (A-Fc) to magnetic beads. This comparative approach allowed for a thorough evaluation of the impact of preparation methods on electrochemical performance. Process 1 involved initial spike protein binding followed by A-Fc attachment, while process 2 reversed this sequence. Process 3 combined both components before attachment. These nanocomplexes were further captured IgG from the samples, and the resulting complexes were detected on anti-IgG-immobilized MWCNT-modified SPE surfaces. Electrochemical techniques, including cyclic voltammetry and differential pulse voltammetry, revealed process 2 as the most effective, demonstrating superior sensitivity and peak current responses. This outcome was supported by Raman spectroscopy and scanning electron microscopy, which highlighted the enhanced chemical modifications and surface morphology achieved through this method. Long-term stability tests showed that process 2 nanocomplexes retained over 90% of their electrochemical activity after 13 weeks. In serum analysis, they demonstrated high recovery rates (90.83%) and low variability, outperforming processes 1 and 3.

In recent years, stimuli-responsive nanoparticles have emerged as one such alternative. These smart nanoparticles are engineered to release drug molecules in response to specific internal or external stimuli, thereby enhancing the precision of drug delivery and improving the therapeutic outcome against malignancies like melanoma. Additionally, some of these nanoparticles are capable of generating reactive oxygen species and excess heat upon activation by specific triggers, enabling them to kill cancer cells directly.

Entry of GNPs in plant cells leads to activation pattern recognition receptors (PRRs), leading to the production of reactive oxygen species (ROS) and the subsequent activation of defense-related genes. In addition, GNPs also induce systemic acquired resistance (SAR) as well as induced systemic resistance (ISR), priming the plant for augmenting defense against a wide range of pathogens.
