Flash nanocomplexation (FNC) offers a scalable method to create curcumin nanoparticles for drug delivery. Lower drug loading in these nanoparticles enhanced cellular uptake and cytotoxicity in prostate cancer cells.
Area of Science:
- Nanotechnology
- Materials Science
- Drug Delivery
Background:
- Curcumin (CUR) is a model small molecule drug with therapeutic potential.
- Developing effective nanoparticular systems for CUR delivery is crucial.
- Hydrogen bonding interactions offer a novel approach for nanoparticle fabrication.
Purpose of the Study:
- To develop a novel flash nanocomplexation (FNC) method for creating curcumin-loaded nanoparticles (NPs).
- To investigate the effect of drug loading levels on NP characteristics and biological activity.
- To evaluate the feasibility of FNC for small molecule drug delivery.
Main Methods:
- Curcumin, tannic acid, and polyvinyl alcohol (PVA) were mixed in aqueous solution.
- Nanoparticles were fabricated using a three-inlet confined impinging jet (CIJ) device under turbulent conditions.
- Drug loading levels were adjusted by varying the CUR feeding amount.
Main Results:
- FNC provided a scalable and reproducible method for NP fabrication, avoiding sequence-dependent variations.
- Three types of CUR-loaded NPs were prepared with varying drug loading levels.
- Cellular uptake and cytotoxicity in PC3 prostate cancer cells were inversely correlated with drug loading levels.
Conclusions:
- Flash nanocomplexation (FNC) is an efficient and feasible method for developing drug-loaded nanoparticles.
- The FNC method utilizes hydrogen bonding interactions for nanoparticle formation.
- Optimizing drug loading is critical for enhancing therapeutic efficacy in cancer treatment.
