Self‐Cleaning Fabrics for Decontamination of Organophosphorous Pesticides and Related Chemical Agents
Source abstract
Abstract
Cotton threads bearing adsorbed branched polyethylenimine–organophosphorous hydrolase (BPEI/OPH) multilayers are woven into cotton cloth (CC) that actively hydrolyzes methyl parathion (MPT) in solution to p-nitrophenol (PNP) over several weeks. These results form the basis for smart fabrics capable of remediation of environmental toxins.

27. Although data for long‐term OPH activity in our samples is not yet available preliminary results obtained for polycyclodextrin microbeads coated with 5 OPH/BPEI bilayers suggest that long‐term viability can be achieved. These coated microbeads have been tested in a column as a filter for removal of MPT from water. Under continuous solution flow (23 ± 2 °C; residence time ∼ 114 s) the filter removed > 99 % of the MPT from a 100 μM MPT input stream for 6 months without failure (i.e. MPT breakthrough).
28. An enzyme assay [2] for the CC/BPEIw/OPHb/BPEIbsystem indicated that ∼ 178 ± 35 μg OPH/mg CC were bound. For the analogous FG/BPEIw/OPHb/BPEIbsystem the level of bound enzyme was below the detection limit of the assay (i.e. < 100 μg OPH/mg FG).
