Enhanced Stability of Multi-Functionalized Gold Nanoparticles and Potential Anticancer Efficacy on Human Cervical...

Area of Science:

• Nanotechnology
• Biomedical Engineering
• Oncology

Background:

• Cervical cancer remains a significant global health challenge.
• Doxorubicin is a key chemotherapeutic agent with limitations in efficacy and side effects.
• Novel drug delivery systems are needed to improve cancer treatment outcomes.

Purpose of the Study:

• To develop and characterize innovative multi-functional gold nanoparticles (GNPs) loaded with doxorubicin (D) and natural molecules (trans-resveratrol (R), piperine (P), and icariin (Ic)).
• To evaluate the anticancer efficacy of these novel nanocarriers against human cervical cancer cell lines (HeLa and CaSki).
• To investigate the potential of these nanocarriers as an improved therapeutic alternative to doxorubicin monotherapy.

Main Methods:

• Synthesis of resveratrol-coated gold nanoparticles (GNP_R1).
• Loading of doxorubicin, resveratrol, piperine, and icariin onto GNPs to create multi-functional nanocarriers (GNP_R1@D/R/P/Ic).
• Comprehensive characterization using techniques like SPR, TEM, HR-TEM, XRD, AFM, DLS, and zeta potential analysis.
• In vitro stability assessments in biological media.
• Cytotoxicity evaluation on HeLa and CaSki cell lines using the MTT assay.

Main Results:

• Successful preparation and characterization of multi-functional GNPs (GNP_R1@D/R and GNP_R1@D/R/P/Ic).
• Demonstrated improved in vitro stability of the multi-functional nanocarriers.
• Enhanced targeting and increased cytotoxicity against human cervical cancer cells (HeLa and CaSki) compared to doxorubicin alone.
• Improved bioavailability of therapeutic agents delivered via the nanocarrier system.

Conclusions:

• The developed multi-functional GNPs effectively combine the benefits of natural biomolecules and functional nanoparticles.
• These innovative nanocarriers show significant potential for enhancing doxorubicin's therapeutic efficacy against human cervical cancer.
• The GNP_R1@D/R/P/Ic nanocarrier system presents a promising and advantageous alternative to conventional doxorubicin monotherapy for cervical cancer treatment.
