Development of Potentiometric Enzyme Biosensor for Detection of Permethrin Preservative in Treated Wood
2017 - IRG/WP 17-20628
Characteristics of a potentiometric enzymatic biosensor based on a pH transducer for permethrin detection in treated wood are reported in this article. The transducer contained a plasticiser-free methacrylic-acrylic membrane immobilised with hydrogen ionophore and a lipophilic salt. A poly(2-hydroxyethyl methacrylate) (pHEMA) was used to immobilise carboxylesterase for the detection of permethrin....

Encapsulation of chlorothalonil with polylactic acid using nanoprecipitation method for rubberwood preservation
2018 - IRG/WP 18-30722
Wood is a very beneficial material for humankind. The current trend is employing organic biocides as wood preservatives to inhibit the wood from biodeterioration caused by fungi and termite. However, these organic biocides are facing some shortcomings when being introduced into the wood using conventional water-based treatment due to their poor water solubility. Polylactic acid (PLA) was employed ...
