Investigation of Optical Properties and Electrical Conductivities of Various Dyes Loaded p(AMPS) Hydrogels

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
