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.

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.
