Özet

Nanopartiküller (NP’ler), nanometre boyutlarında olup yüksek yüzey alanı, özgün optik, manyetik ve kimyasal özellikleri sayesinde birçok bilimsel ve teknolojik alanda önemli uygulamalara sahiptir. Bu bölümde, NP’lerin tanımı ve biyomedikal önemine odaklanılarak, farklı sentez yöntemleri (fiziksel, kimyasal ve biyolojik yaklaşımlar) ele alınmıştır. Öğütme, sol-jel, kimyasal çöktürme ve mikroemülsiyon gibi yöntemlerin temel prensipleri, avantajları ve sınırlılıkları açıklanmış; uygun yöntemin seçiminde uygulama amacının belirleyici olduğu vurgulanmıştır. Ayrıca, sentezlenen NP’lerin karakterizasyonu için kullanılan teknikler tanıtılmış; bu tekniklerle elde edilen verilerin NP’lerin biyolojik davranışları açısından önemi tartışılmıştır. Son olarak, NP’lerin olası toksikolojik etkilerine ve insan sağlığı üzerindeki risklerine değinilmiş, bu risklerin değerlendirilmesi için gerekli in vitro ve in vivo test yöntemleri özetlenmiştir. Bu bölüm, NP’lerin sentezinden karakterizasyonuna ve güvenlik değerlendirmesine kadar uzanan bütüncül bir bakış sunarak, sağlık alanında güvenli ve etkili uygulamalar geliştirilmesine katkı sağlamayı amaçlamaktadır.

"Nanoparticles (NPs), which are on the nanometer scale, possess a high surface area and unique optical, magnetic, and chemical properties, making them highly applicable in numerous scientific and technological fields. This chapter focuses on the definition and biomedical significance of NPs, addressing various synthesis methods, including physical, chemical, and biological approaches. The fundamental principles, advantages, and limitations of techniques such as milling, sol-gel, chemical precipitation, and microemulsion are explained, emphasizing that the intended application is a key factor in selecting the appropriate method. Additionally, techniques used for the characterization of synthesized NPs are introduced, and the importance of the data obtained from these techniques for understanding the biological behavior of NPs is discussed. Finally, the potential toxicological effects of NPs and their risks to human health are addressed, with an overview of the in vitro and in vivo testing methods required for risk assessment. This chapter aims to provide a comprehensive perspective from nanoparticle synthesis to characterization and safety evaluation, contributing to the development of safe and effective applications in the field of health.
