The use of nanoparticles as a promising therapeutic approach in cancer immunotherapy

Area of Science:

• Oncology
• Materials Science
• Biotechnology

Background:

• Cancer remains a leading global cause of death with limited treatment efficacy.
• Conventional therapies like chemotherapy often cause severe side effects, including toxicity and drug resistance.
• Nanoparticle-mediated drug delivery systems (DDS) show promise for targeted cancer treatment.

Purpose of the Study:

• To review the role of nanotechnology in cancer drug delivery.
• To introduce nanomaterials and their characteristics for tumor therapy.
• To highlight passive and active targeting strategies using ligands like single chain variable fragments (scFv).

Main Methods:

• Review of current literature on nanotechnology in cancer therapy.
• Discussion of passive and active targeting strategies for drug delivery.
• Focus on nanomaterials and their properties relevant to tumor targeting.

Main Results:

• Nanoparticle DDS can enhance cancer treatment by delivering therapeutics directly to tumor sites.
• Targeted delivery reduces adverse effects on healthy tissues.
• Antibodies, specifically single chain variable fragments (scFv), are key ligands for active targeting.

Conclusions:

• Nanotechnology provides a powerful platform for developing advanced cancer drug delivery systems.
• Targeted delivery using nanomaterials and specific ligands like scFv can significantly improve treatment outcomes.
• Further research into nanoparticle-based DDS holds potential for more effective and safer cancer therapies.
