Functionalized carbon nanotubes for anticancer drug delivery

Area of Science:

• Nanotechnology
• Materials Science
• Pharmacology

Background:

• Functionalized carbon nanotubes (f-CNTs) are being explored for novel anticancer drug delivery systems.
• Current methods involve covalent or physical attachment of drugs to CNTs, often using poly(ethylene glycol) for improved solubility and biocompatibility.

Purpose of the Study:

• To review the potential of f-CNTs in anticancer drug delivery.
• To highlight the importance of well-controlled f-CNT structures for mechanistic studies and improved therapeutic efficacy.

Main Methods:

• Literature review of in vitro and in vivo studies on f-CNT drug delivery systems.
• Analysis of functionalization strategies and drug loading techniques for CNTs.
• Examination of the role of poly(ethylene glycol) in enhancing CNT properties.

Main Results:

• f-CNTs demonstrate potential for delivering anticancer drugs like paclitaxel and doxorubicin, with proven efficacy in preclinical models.
• Poly(ethylene glycol) functionalization enhances CNT dispersity and biocompatibility.
• The lack of f-CNTs with uniform structures hinders a clear understanding of cellular uptake mechanisms.

Conclusions:

• Functionalized carbon nanotubes hold significant promise for developing advanced anticancer therapeutics.
• Achieving well-defined f-CNT structures is crucial for resolving mechanistic debates and advancing their application as drug delivery platforms.
