Area of Science:

  • Materials Science
  • Pharmaceutical Sciences
  • Biotechnology

Background:

  • Microparticulated drug delivery systems enhance drug stability, bioavailability, and reduce adverse effects.
  • Alginate microparticles are increasingly researched for drug and cell delivery due to their effectiveness.
  • Calcium alginate microparticles offer prolonged drug release and mucoadhesive properties.

Purpose of the Study:

  • To produce Ca-alginate micro-vehicles using electrospraying.
  • To optimize alginate and CaCl2 concentrations for desired microparticle characteristics.
  • To evaluate encapsulation efficiency, protein release, swelling, and sphericity.

Main Methods:

  • Electrospraying technique for Ca-alginate micro-vehicle fabrication.
  • Design of Experiments (DOE) to optimize formulation parameters.
  • Statistical analysis including p-value and coefficient of determination.

Main Results:

  • High encapsulation efficiency (EE%), reduced protein release, and minimal swelling achieved.
  • High sphericity coefficient indicating well-formed microparticles.
  • Statistically significant DOE model (p < 0.05) with high coefficients of determination (0.9207–0.9637).

Conclusions:

  • Optimal formulation identified at 4% alginate and 6.6% CaCl2.
  • Validated optimal point confirms successful production of Ca-alginate micro-vehicles.
  • Electrospraying is a viable method for creating effective drug delivery micro-vehicles.
