摘要： The invention provides methods and materials for decontamination of surfaces and fabrics, such as non-woven fabrics, that are contaminated with infestations of microorganisms such as bacteria. Biocidal oligomers having conjugated oligo-(aryl/heteroaryl ethynyl) structures and comprising at least one cationic group can be used to decontaminate infested surfaces in the presence of oxygen and, optionally, illumination. Fibers incorporating biocidal oligomers having conjugated oligo-(aryl/heteroaryl ethynyl) structures and comprising at least one cationic group, wherein the oligomer is physically associated with or covalently bonded to, or both, the fiber-forming polymer can be used to form non-woven mats. Biocidal non-woven mats prepared by methods of the invention, incorporating the biocidal oligomers, can be used to suppress bacterial growth in wound and surgical dressings and personal hygiene products.

摘要： Hollow conjugated polyelectrolyte (HCPE) microcapsules contain at least one conjugated polyelectrolyte and at least one other polyelectrolyte of complementary charge and the microcapsule has a hollow core. The conjugated polyelectrolyte is a polymer with a multiplicity of charged repeating units where a portion of the charged repeating units form a pi-conjugated sequence. The complementary polyelectrolyte is a polymer with a complementary charged repeating unit to the charged repeating units of the conjugated polyelectrolyte. The HCPE microcapsules can be formed by successively coating a sacrificial core with alternating layers of complementary polyelectrolytes, at least one of which is a conjugated polyelectrolyte. The sacrificial core can be removed to form the hollow center of a HCPE microcapsule. The HCPE microcapsules can be contacted with a medium containing microbes where the HCPE microcapsules associate with the microbes and efficiently kill the microbes when irradiated with light or other electromagnetic radiation.

摘要： Various embodiments disclosed relate to conjugated polyelectrolytes and methods of using the same. Various embodiments provide a conjugated polyelectrolyte including a subunit having the structure —R1—Y—R2—Z—. At each occurrence, R1 is independently chosen from 1,4-bonded phenylene substituted by —X—R3—R4 j times and 2,5-bonded thiophene substituted by —X—R3—R4 j times. At each occurrence, Y is independently chosen from a bond and —C≡C—. At each occurrence, R2 is independently chosen from a bond, a substituted or unsubstituted phenylene, thiophenylene, azulenylene, heptalenylene, biphenylene, indacenylene, fluorenylene, phenanthrenylene, triphenylenylene, pyrenylene, naphthacenylene, chrysenylene, biphenylenylene, anthracenylene, and naphthylene. At each occurrence, Z is independently chosen from a bond and —C≡C—. The variables j, R3, and R4 are as defined herein.

摘要： The invention relates to compositions including a charged oligo-phenylene ethynylene singlet-oxygen sensitizer and an oppositely-charged surfactant, which show an enhanced biocidal activity relative to a comparable concentration of the oligo-phenylene ethynylene without the oppositely-charged surfactant. The enhancement of biocidal activity is observed with an anionic oligo-phenylene ethynylene in the presence of a cationic surfactant such as TTAB, and with a cationic oligo-phenylene ethynylene in the presence of an anionic surfactant such as SDS.
