    • Samples taken before and after the gelation reactions were diluted to a concentration of 26 mg/L, and their UV absorbencies at 260 nm were recorded. The rise of the optical absorbance, normalized with respect to that measured before the reaction, was less than 1.008 for EGDE contents between 0 and 2.5%. Assuming that the DNA strands melt completely, a rise of the normalized absorbance to 1.4 is expected. The results thus suggest that the solutions and gels contain less than 2% ss-DNA fragments after the reactions. At higher EGDE contents, UV measurements cannot be conducted due to the insolubility of the samples in water.
