Photostability assessment of natural pyrethrins using halloysite nanotube carrier system

Antimicrobial Nanomaterials Based on Halloysite Clay Mineral: Research Advances and Outlook

“…The loading of pyrethrum extract into HNTs’ lumen led to the synthesis of nanopesticides where, because of the presence of HNTs, the active ingredients are protected from UV light and slowly released over time. In addition, in vivo tests on two different insects, G. mellonella and T. molitor , chosen as pest models, showed that the nanomaterial was highly active on the first one at a half dose compared to a commercial pesticide [ 89 ].…”

Green liquid marble-based hydrogels as pesticidal pyrethrin slow-release carriers

“…Early studies have provided some methods that are used to solve the above problems. Researchers prepared pyrethrin formulations in which pyrethrin was loaded with natural poly-mers, 13 inorganic non-metallic materials 14 and nano-mixed micelles. [15][16][17] Among various natural polymers, alginates are used extensively in the preparation of hydrogel microspheres, micro-capsules and membranes for controlled drug release because of their biocompatible, biodegradable and nontoxic properties.…”

Exploiting the interaction between halloysite and charged PNAs for their controlled release

“…5 In addition, the opposite charges at surfaces were exploited for the immobilization, by electrostatic attraction interactions, of different molecules to obtain innovative nanomaterials for different purposes. 6,7 In this context, proteins or enzymes were selectively immobilized at the external surface or loaded into the lumen by working in pH ranges above or below their isoelectric points. 8 In this way, efficient nanocontainers for drug delivery or biomimetic nanoreactors were successfully synthesized.…”
