In this study,poly(2-acrylamido-2-methyl-propanesulfonic acid) (p(AMPS)) type hydrogels weresynthesized and afterwards giemsa stain (GS), methylene blue (MB) and rhodamin6G (R6G) dyes were loaded to the hydrogels. Because of the reason that thesehydrogels possess hydrophilic groups such as–OH, -NH2, -SO3H, -PO3H, -COOH in theirstructures; they have various applications in many fields such as medical,biomedical, pharmacy, cosmetic, agriculture, environment. GS, MB, R6G dyes,that could be bonded to gene, protein, DNA, often used in chemistry,biology and medical applications such as diagnosis and treatment, pHdetermination and in industrial applications that requires the use of dyes. Asa result of their fluorescence properties, they could be used in variousoptical applications. The optical properties of the synthesized and dye loadedhydrogels were analyzed by ultraviolet-visible (UV-Vis) absorption spectrophotometerand fluorescence spectrophotometry. As a result of these analysis, it isdetermined that the optical properties of the dyes were also observed in thedye loaded p(AMPS) hydrogels. Additionally, the electrical properties of thep(AMPS) hydrogels and dye loaded hydrogels were investigated by roomtemperature conductivity measurements. The analysis of the electrical andoptical properties showed that dye loaded p(AMPS) hydrogels have potential tobe used in medical applications and optical applications such as LED, solarcells, optical filters.

Bu çalışmada, öncelikle poli(2-akrilamido-2-metilpropan sülfonikasit) (p(AMPS)) türü hidrojellersentezlenmiş ve sonrasında giemsa stain (GS), methylene blue (MB) ve rhodamin6G (R6G) boya maddeleri ile yüklenmiştir. Hidrojeller yapılarında suyu sevenbirçok fonksiyonel gruba sahip olabilmeleri nedeniyle özellikle tıp,biyomedikal, eczacılık, kozmetik, tarım, çevre gibi pek çok alanda uygulamaimkânına sahiptir. GS, MB, R6G boya maddeleri gen, protein, DNA gibi maddelerebağlanabilmeleri sayesinde kimya, biyoloji ve tıpta pH ayarlama ve belirleme,hastalık teşhis ve tedavisi gibi uygulamalarda ve endüstride de boya gerektirenuygulamalarda sıklıkla kullanılmaktadırlar. Floresan özellik göstermelerisayesinde çeşitli optik uygulamalarda da kullanım alanına sahiptirler.Sentezlenen ve boya yüklenen hidrojellerin optik özellikleri morötesi-görünürbölge (UV-Vis) soğurma spektrofotometre ve floresans spektrofotometre ileanaliz edilmiştir. Bu analizler sonucunda, bu boyaların optik özelliklerininboya yüklenen p(AMPS) hidrojellerde de gözlemlendiği belirlenmiştir. p(AMPS)hidrojellerin ve boya yüklenmiş hidrojellerin elektriksel özellikleri odasıcaklığında iletkenlik ölçümleri ile incelenmiştir. Elektriksel ve optiközelliklerinin analizleri boya yüklenmiş p(AMPS) hidrojellerin tıbbiuygulamalarda, LED, güneş gözesi, optik filtre gibi optoelektronikuygulamalarda kullanılma potansiyeline sahip olduğunu göstermiştir.
