Abstract
Tr en Bu çalışmada, öncelikle poli(2-akrilamido-2-metilpropan sülfonik asit) (p(AMPS)) türü hidrojeller sentezlenmiş ve sonrasında giemsa stain (GS), methylene blue (MB) ve rhodamin 6G (R6G) boya maddeleri ile yüklenmiştir. Hidrojeller yapılarında suyu seven birçok fonksiyonel gruba sahip olabilmeleri nedeniyle özellikle tıp, biyomedikal, eczacılık, kozmetik, tarım, çevre gibi pek çok alanda uygulama imkânına sahiptir. GS, MB, R6G boya maddeleri gen, protein, DNA gibi maddelere bağlanabilmeleri sayesinde kimya, biyoloji ve tıpta pH ayarlama ve belirleme, hastalık teşhis ve tedavisi gibi uygulamalarda ve endüstride de boya gerektiren uygulamalarda sıklıkla kullanılmaktadırlar. Floresan özellik göstermeleri sayesinde çeşitli optik uygulamalarda da kullanım alanına sahiptirler. Sentezlenen ve boya yüklenen hidrojellerin optik özellikleri morötesi-görünür bölge (UV-Vis) soğurma spektrofotometre ve floresans spektrofotometre ile analiz edilmiştir. Bu analizler sonucunda, bu boyaların optik özelliklerinin boya yüklenen p(AMPS) hidrojellerde de gözlemlendiği belirlenmiştir. p(AMPS) hidrojellerin ve boya yüklenmiş hidrojellerin elektriksel özellikleri oda sıcaklığında iletkenlik ölçümleri ile incelenmiştir. Elektriksel ve optik özelliklerinin analizleri boya yüklenmiş p(AMPS) hidrojellerin tıbbi uygulamalarda, LED, güneş gözesi, optik filtre gibi optoelektronik uygulamalarda kullanılma potansiyeline sahip olduğunu göstermiştir. In this study, poly(2-acrylamido-2-methyl-propanesulfonic acid) (p(AMPS)) type hydrogels were synthesized and afterwards giemsa stain (GS), methylene blue (MB) and rhodamin 6G (R6G) dyes were loaded to the hydrogels. Because of the reason that these hydrogels possess hydrophilic groups such as –OH, -NH2, -SO3H, -PO3H, -COOH in their structures; 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, pH determination and in industrial applications that requires the use of dyes. As a result of their fluorescence properties, they could be used in various optical applications. The optical properties of the synthesized and dye loaded hydrogels were analyzed by ultraviolet-visible (UV-Vis) absorption spectrophotometer and fluorescence spectrophotometry. As a result of these analysis, it is determined that the optical properties of the dyes were also observed in the dye loaded p(AMPS) hydrogels. Additionally, the electrical properties of the p(AMPS) hydrogels and dye loaded hydrogels were investigated by room temperature conductivity measurements. The analysis of the electrical and optical properties showed that dye loaded p(AMPS) hydrogels have potential to be used in medical applications and optical applications such as LED, solar cells, optical filters.Keywords
