Cationic conjugated polyelectrolytes (CPE) and oligomer electrolytes (OPE) exhibit profound light activated biocidal activity.  The presentation will describe various CPE and OPE structures and synthetic methods used to fabricate them into various material formats at interfaces and on the surface of colloids.  The light activated biocidal activity is related in part to the ability of the CPE and OPE to efficiently generate singlet oxygen following absorption of a near-UV or visible photon.  The mechanism of light activated biocidal activity will be discussed, and structure-property relationships for singlet oxygen generation and biocidal activity will be discussed.
