Polyacrylamide hydrogels physically crosslinked by double-stranded DNA have demonstrated potential for drug delivery, biosensing, and tissue engineering due to their programmability, mechanical tunability, molecular-recognition, and temperature reversibility. For some applications, introducing chemical crosslinks (e.g., bis-acrylamide) to the gel network is necessary. This thesis provides fundamental understanding of bis-, DNA-, and dual-crosslinked gels from macrorheology and swelling. In the rheological studies, dynamic shear moduli in the linear viscoelastic regime were measured during and following gelation, followed by creep-recovery. Swelling tests were undertaken to investigate the gel durability in the solvent. It was found that gel...
