Tiyol grupları içeren aminoasitler olarak Sistein (Cys) ve homosistein (Hcy) biyolojik sistemlerde birçok önemli rol oynamaktadır. HCy’nin plazma seviyesinin, kardiyovasküler ve Alzheimer gibi bazı hastalıkların bir göstergesi olduğu bilinmektedir. Plazmadaki Cys eksikliği karaciğer hasarı, kas ve yağ kaybı, cilt lezyonları, yavaş büyüme vb. Gibi durumlarla ilişkilidir. Bu çalışmada, Cys seviyelerinin belirlenmesi için floresan tabanlı bir metot geliştirilmek üzere yüksek fotolüminesans etkinlik gösteren iridium kompleksleri seçilmiştir. Daha sonra sentezlenen kompleks, Cys çözeltileriyle etkileştirilmiştir. İridyum kompleksiyle etkileşen Cys derişimi arttıkça çözeltinin floresans şiddetinin de arttığı bulunmuştur. Buradan yola çıkarak, sentezlenen iridyum kompleksinin, serum örneklerinde Cys seviyesinin florimetrik tayininde kullanılabileceği düşünülmektedir.
