Objective: The aim of this study is to optimize the formulation of insulin-loaded poly-caprolactone nanoparticles (INS-PCL-NP) for use in chronic wound healing using Box-Behnken experimental design.
Material and Method: The response of independent variables (poly-caprolactone concentration, polyvinyl alcohol concentration and sonication time) on dependent variables (particle size, PDI and encapsulation efficiency) were evaluated. Nanoparticle formulations were produced by the double emulsion (w/o/w)-solvent evaporation method. The resulting formulations were characterized in terms of particle size, zeta potential, and encapsulation efficiency to determine the optimum formulation. Further analyses, including morphological analyses, Fourier-transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and in vitro drug release studies were conducted on the optimized formulation.
Result and Discussion: According to the results of the characterization studies, it was observed that the optimized nanoparticles had a particle size of 618.5±11.2 nm, a PDI of 0.194±0.021, a zeta potential of -8.21±1.1 mV and an encapsulation efficiency of 73.1±4.2%. In morphological analysis, it was observed that the nanoparticles had a spherical structure. The optimized nanoparticle formulation showed a rapid release of 49.1±2.1% within the first 24 hours, followed by a controlled release for 168 hours.

KRONİK YARA İYİLEŞMESİ İÇİN İNSÜLİN YÜKLÜ POLİ-KAPROLAKTON NANOPARTIKÜLLERİNİN BOX-BEHNKEN DENEYSEL TASARIMI KULLANILARAK OPTİMİZASYONU

Öz

Amaç: Bu çalışmanın amacı kronik yara iyileşmesinde kullanılmak üzere insülin yüklü poli-kaprolakton nanopartiküllerinin (INS-PCL-NP) formülasyonunu Box-Behnken deneysel tasarımı kullanarak optimize etmektir.
Gereç ve Yöntem: Bağımsız değişkenlerin (poli-kaprolakton konsantrasyonu, polivinil alkol konsantrasyonu ve sonikasyon süresi) bağımlı değişkenlere (partikül boyutu, PDI ve kapsülleme verimliliği) tepkisi değerlendirilmiştir. Nanopartikül formülasyonları çift emülsiyon (s/y/s)-çözücü buharlaştırma yöntemi ile üretilmiştir. Optimum formülasyonu belirlemek için nanopartiküller partikül boyutu, zeta potansiyeli ve enkapsülasyon etkinliği açısından karakterize edilmiştir. Deneysel tasarıma uygun olarak belirlenen optimum nanopartikül formülasyonu ile morfolojik analizler, FTIR, DSC analizleri ve in vitro ilaç salım çalışmaları yapılmıştır.
Sonuç ve Tartışma: Karakterizasyon çalışmalarının sonuçlarına göre, optimize edilmiş nanopartiküllerin 618.5±11.2 nm partikül boyutuna, 0.194±0.021 PDI'ye, -8.21±1.1 mV zeta potansiyeline ve %73.1±4.2 enkapsülasyon etkinliğine sahip olduğu görülmüştür. Morfolojik analizde, nanopartiküllerin küresel bir yapıya sahip olduğu görülmüştür. Optimize edilmiş nanopartikül formülasyonu, ilk 24 saat içinde %49.1±2.1'lik ilk salım, ardından 168 saat boyunca kontrollü salım göstermiştir.
