Abstract :
در اين مقاله نانوهيدروكسي آپاتيت سنتز شد و در ادامه جهت كنترل رهايش داروي سولفاسالازين نانوهيدروكسي آپاتيت توسط 3-آمينوپروپيل تري متوكسي سيلان عامل دار شد. نتايج نشان داد كه هيدروكسي آپاتيت عامل دار شده سرعت رهايش كندتري نسبت به هيدروكسي آپاتيت عامل دار نشده دارد. از طرف ديگر مقادير داروي زيادتري مي توان در هيدروكسي آپاتيت عامل دار شده لود گرد. نانوهيدروكسي آپاتيت سنتز شده با پراش اشعه X،ميكروسكوپ الكتروني روبشي، اسپكتروسكوپي مادون قرمزو اسپكتروسكوپي UV-Visبررسي شد.
Abstract :
In this work we synthesized Nano hydroxyapatite (HAp) by Sol-
gel method, Then we functionalized hydroxyapatite nanoparticle by
use of 3-Aminopropyl trimethoxysilane (APTMS) , to improve the
loading and control release of sulfasalazine drug bonded to
APTMS. The drug release patterns from Sulfasalazine loaded HAp
nanoparticles at pH value 8 For 6h, Sulfasalazine loaded
functionalized HAp nanoparticles (Sulfasalazine loaded HAp-
APTMS) at pH value 8 as in the intestine for 48h. Moreover, the
functionalized HAp showed relatively slower release rate of
sulfasalazine compare with non functionalized HAp. because the
strong ionic interaction between NH2 group in sulfasalazine in
HAp-APTMS. On other side, the functionalized HAp loaded more
drug than pure HAp. The synthesized nanoparticles and
functionalized HAp characterized by Scanning Electron
Microscopy (SEM), X-ray Diffraction (XRD), Fourier transform
infrared (FT-IR) and UV/Vis analysis techniques. Then the
obtained material was studied in the simulated body fluid (SBF) to
this investigated storage and release properties.
