چکیده
شیشه‌های زیست‌فعال پایه‌ی سیلیکاتی و پایه‌ی فسفاتی فسفاتی حاوی CaO، به‌دلیل توانایی خود در تشکیل پیوندی مستحکم با بافت میزبان، نرخ حل‌شوندگی مطلوب و تأثیر آن در تشکیل لایه‌ی هیدروکسی‌آپاتایت، تحریک رشد سلولی و رفتار مکانیکی، ترکیبات پرکاربردی در مهندسی بافت هستند. اخیراً روش‌ شبیه‌سازی دینامیک مولکولی به‌عنوان روشی کارآمد در پیش‌بینی خواص و ساختار شیشه‌های زیست‌فعال در کنار روش‌های تجربی استفاده شده است. ازاین‌رو، در این پژوهش به مطالعه‌ی ترکیب شیشه‌ی زیست‌فعال دوجزئی 50SiO2-50CaO و50P2O5-50CaO به روش دینامیک مولکولی پرداخته شد. با استفاده از تابع توزیع پیوندی و تابع توزیع زاویه‌ای به بررسی اندازه‌ی زاویه‌ی بین پیوندی و اندازه‌ی پیوندها پرداخته شد و توزیع اکسیژن‌های پل‌زن و غیرپل‌زن در دو ترکیب شیشه‌ی زیست‌فعال محاسبه شد که در شیشه‌ی زیست‌فعال 50SiO2-50CaO و50P2O5-50CaO به‌ترتیب 34/62 درصد و 32/9 درصد اکسیژن پل‌زن توزیع شده است. همچنین، توزیع مقادیر Qn در دو شیشه‌ی زیست‌فعال 50SiO2-50CaO و50P2O5-50CaO مطالعه شد که در شیشه‌ی زیست‌فعال 50SiO2-50CaO و50P2O5-50CaO توزیع Q2 به‌عنوان معیاری مناسب برای تخریب‌پذیری آن‌ها، به‌ترتیب 42/9 درصد و 59/03 درصد است. ضمن اینکه، مقادیر چگالی برای دو ترکیب شیشه‌ی زیست‌فعال 50SiO2-50CaO و50P2O5-50CaO به‌ترتیب مقادیر g/cm32/81 و 2/15 به دست آمد و غلظت بالاتر یون‌های کلسیم و میزان بالاتر pH در شیشه‌ی زیست‌فعال 50P2O5-50CaO نسبت به 50SiO2-50CaO گزارش شد. بنابراین، طبق نتایج مذکور، شیشه‌ی زیست‌فعال 50P2O5-50CaO به‌دلیل دارا بودن مقادیر اکسیژن غیرپل‌زن و Q2 بالاتر دارای تخریب‌پذیری بالاتر و به‌تبع آن رهایش یون بیشتری از شیشه‌ی زیست‌فعال 50SiO2-50CaO است.

چکیده English

Silicate-based and phosphate-based bioactive glasses (BGs) containing CaO are widely used compounds in tissue engineering (TE) due to their ability to form a strong bond with the host tissue, favorable dissolution rate, their effect on the formation of a hydroxyapatite (HA) layer, stimulation of cell growth, and mechanical behavior. Recently, molecular dynamics (MD) simulation has been used as an efficient method to predict the properties and structure of BGs in addition to experimental methods. Therefore, in this study, the binary BG composition of 50SiO2-50CaO and 50P2O5-50CaO was studied by MD method. Using the bond distribution function and the angular distribution function, the size of the interbond angle and the size of the bonds were investigated, and the distribution of bridging oxygens (BOs) and non-bridging oxygens (NBOs) in two BG compositions was calculated, which in the 50SiO2-50CaO and 50P2O5-50CaO were distributed 34.62% and 32.9% of BOs, respectively. Also, the distribution of Qn values in 50SiO2-50CaO and 50P2O5-50CaO BGs was studied, and in 50SiO2-50CaO and 50P2O5-50CaO BGs, the distribution of Q2 as a suitable criterion for their degradability was 42.9% and 59.03%, respectively. Meanwhile, the density values for the 50SiO2-50CaO and 50P2O5-50CaO BG compositions were 2.381 and 2.15 g/cm3, respectively, and a higher concentration of calcium ions and a higher pH were reported in 50P2O5-50CaO than in 50SiO2-50CaO BGs. Therefore, according to the mentioned results, 50P2O5-50CaO BG has higher degradability and consequently higher ion release than 50SiO2-50CaO BG due to its higher NBOs and Q2 values.
