Nanoparticle therapeutics: Technologies and methods for overcoming cancer

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Oncology

Background:

• Cancer remains a leading cause of mortality, with an estimated 13 million deaths by 2030.
• Multidrug resistance (MDR) significantly limits the efficacy of conventional cancer therapies, leading to poor patient outcomes.
• Nanotechnology offers novel approaches for targeted drug delivery to combat cancer.

Purpose of the Study:

• To review the application of nanotechnology in developing therapeutic nanoparticles for cancer treatment.
• To explore the enhanced permeability and retention (EPR) effect and its role in preferential tumor targeting.
• To understand the design principles for nanoparticles to overcome MDR and improve cancer therapy.

Main Methods:

• Review of existing literature on nanoparticle-based drug delivery systems for cancer.
• Discussion of nanoparticle manufacturing and functionalization techniques.
• Analysis of the enhanced permeability and retention (EPR) effect and its mechanisms in tumor targeting.

Main Results:

• Functionalized nanoparticles can overcome various MDR mechanisms both in vitro and in vivo.
• Nanoparticle drug delivery can reduce the side effects associated with conventional chemotherapy.
• The EPR effect facilitates the passive accumulation of nanoparticles within tumor tissues.

Conclusions:

• Therapeutic nanoparticles represent a promising strategy to enhance cancer treatment efficacy.
• Understanding the EPR effect is crucial for designing effective nanoparticle-based drug delivery systems.
• Nanotechnology holds significant potential to overcome multidrug resistance and improve patient prognosis in oncology.
