Area Of Science

  • Biomaterials Science
  • Nanotechnology
  • Cancer Therapeutics

Background

  • Melanoma presents a significant health challenge requiring effective treatments.
  • Disulfiram-copper complex (DS-Cu) shows promise as an anticancer agent.

Purpose Of The Study

  • To encapsulate the DS-Cu complex into a polyvinyl alcohol (PVA) nanofiber scaffold (DS-Cu@PVA).
  • To enhance bioavailability and reduce toxicity of DS-Cu for melanoma treatment.

Main Methods

  • Fabrication of the nanofiber scaffold using electrospinning.
  • Characterization via ART-Fourier transform infrared spectroscopy (ART-FTIR), scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDX).
  • Assessment of cellular cytotoxicity, flow cytometry, and caspase 3 activity.

Main Results

  • Successful encapsulation of DS-Cu into PVA nanofibers confirmed by characterization techniques.
  • SEM showed consistent nanofiber diameter; ATR-FTIR indicated no significant alteration of PVA peaks.
  • DS-Cu@PVA exhibited superior biocompatibility with normal skin cells and enhanced melanoma cell apoptosis via increased reactive oxygen species and caspase 3 activity.

Conclusions

  • The DS-Cu@PVA nanofiber scaffold demonstrates enhanced biocompatibility and potent cytotoxic effects on melanoma cells.
  • Targeted delivery of DS-Cu via PVA nanofibers offers a promising strategy for melanoma therapy.
