Recent Advances in the Pharmaceutical and Biomedical Applications of Cyclodextrin-Capped Gold Nanoparticles

Area of Science:

• Pharmaceutical Sciences
• Nanotechnology
• Materials Science

Background:

• Poor aqueous solubility, low permeability, and short half-life of drugs are major pharmaceutical preparation challenges.
• Conventional drug delivery systems often fail to address these limitations effectively.
• Cyclodextrins (CDs) and their derivatives show promise in overcoming these drug formulation issues.

Purpose of the Study:

• To review the history, properties, and applications of cyclodextrins, focusing on inclusion complex formation.
• To explore the effects of cyclodextrins on drug solubility, bioavailability, and stability.
• To investigate the preparation and application of gold nanoparticles (AuNPs) as novel drug delivery systems, particularly when combined with cyclodextrins.

Main Methods:

• Review of literature on cyclodextrin properties and applications in drug delivery.
• Analysis of the synergistic effects of combining cyclodextrins with gold nanoparticles.
• Exploration of the preparation methods and characterization of cyclodextrin-gold nanoparticle conjugates.

Main Results:

• Cyclodextrins enhance drug solubility, loading capacity, stability, and size control of gold nanoparticles.
• Gold nanoparticles offer advantages like ease of detection, targeted delivery, and high loading efficiency.
• CD-AuNP systems combine the benefits of both components for improved drug delivery.

Conclusions:

• CD-derived AuNPs present significant potential for pharmaceutical applications, including antibacterial, anticancer, and gene-drug delivery.
• These systems are valuable for targeted drug delivery and various biomedical applications.
• Cyclodextrins also play a role in preparing catalytic enzymes, molecular print boards, functionalized electrodes, and biosensors.
