Some novel aspects of DNA physical and chemical gels
DNA chemical and physical networks have been investigated with respect to their stability and swelling, and rheological properties. Chemical networks were prepared by cross-linking DNA with ethylene glycol diglycidyl ether (EGDE), and physical networks by association with cationic polymers. Both types of gels display strong elastic properties and have a shear thinning behaviour. Addition of cationic surfactants effectively collapses the chemical gels, de-swelling starting from a criticaldoi:10.3998/ark.5550190.0007.411 fatcat:yls7kikrxrgn5gr4dpg3v3ziqu
