- CuO NPs-loaded nanospheres retain their visibility in T1-weighted MRI, suggesting their potential as multifunctional nanomaterials for imaging and drug delivery.
MRI Contrast Enhancement:
- CuO NPs induce a concentration-dependent shortening of the T1 relaxation time, significantly increasing the contrast-to-noise ratio in MRI scans .
- The incorporation of copper into iron oxide nanoparticles improves their relaxivity, making them effective T2 MRI contrast agents.
Biocompatibility and Stability:
- CuO NPs encapsulated within polymeric nanospheres exhibit controlled release and maintain their imaging capabilities, indicating good biocompatibility and stability.
- Graphene encapsulation of copper microwires eliminates cytotoxicity, making them suitable for MRI-compatible neural electrodes.
Multifunctional Capabilities:
- CuO NPs demonstrate potential for use in both diagnostic imaging and therapeutic applications, such as photothermal therapy (PTT) and photoacoustic imaging (PAI) .
- Copper sulfide nanoparticles (CuS NPs) functionalized with manganese chelates show promise for MRI and PAI dual-modal imaging, enhancing their utility in cancer therapy.

Conclusion

Copper oxide nanoparticles exhibit significant potential as contrast agents for MRI imaging, with additional capabilities for dual-modality imaging and therapeutic applications. Their ability to enhance MRI contrast, combined with good biocompatibility and multifunctional properties, positions them as promising tools in the field of medical imaging and theranostics. Further in-vivo studies are warranted to fully explore their clinical utility.
