Adsorption of a carcinogenic agent, acridine orange, to DNA liquid crystalline gel (LCG) and DNA-combined poly(dimethylsiloxane) (DNA-PDMS) have been measured as a function of time. The adsorption process is represented by the stretched exponential function for both the DNA LCG and the DNA-PDMS. The experimental data of the adsorption process are compared with a simple model based on the diffusion process of acridine orange. For the DNA LCG, the adsorption rates are affected by preparation conditions. The DNA LCG with higher cross-linking density shows slower adsorption of acridine orange. The DNA-PDMS is a new DNA-based material with high elastic modulus, which is expected for use under high stress.
