Area of Science:

Materials Science
Drug Delivery
Nanotechnology

Background:

Optimal curcumin delivery necessitates systems that enhance solubility and prevent degradation.
Chitosan and Tween 20 offer potential for creating effective drug delivery vehicles.

Purpose of the Study:

To encapsulate curcumin within submicrometer chitosan/Tween 20 particles using spray-drying.
To optimize spray-drying parameters for minimizing particle size and achieving spheroid morphology.

Main Methods:

Utilized a Taguchi statistical approach to optimize spray-drying parameters.
Employed scanning electron microscopy (SEM) for particle characterization (size, shape, surface).
Conducted curcumin encapsulation and in vitro release studies.

Main Results:

Achieved nearly spherical chitosan/Tween 20 particles with a diameter of 285 ± 30 nm and an axial ratio of 1.21.
Demonstrated complete encapsulation of curcumin within the spray-dried particles.
Confirmed complete curcumin release from the particles within a 2-hour timeframe.

Conclusions:

Spray-drying is an effective method for producing curcumin-loaded chitosan/Tween 20 nanoparticles.
The optimized process yields nanoparticles suitable for efficient curcumin delivery.
These nanoparticles show promise for enhancing curcumin's therapeutic applications.
