“…The intercalated pesticide has higher thermal stability. The release rates and equilibrium release amounts of the pesticide were closely dependent on micelles types and release media [69] Other pesticides that were intercalated into Zn-LH are 3-(4-methoxyphenyl) propionic [63], imidacloprid [64], 4-(2,4-dichlorophenoxy) butyrate and 2-(3-chlorophenoxy) propionate [65] and 2-methyl-4-chlorophenoxyacetic [66]. They were synthesized due to their superior qualities compared with their counterparts.…”

The rapid growth in the human population has triggered increased demand for food supply, and in turn has prompted a higher amount of agrochemical usage to meet the gaps between food production and consumption. The problem with conventional agro-nanochemicals is the reduced effectiveness of the active ingredient in reaching the target, along with leaching, evaporation, etc., which ultimately affect the environment and life, including humans. Fortunately, nanotechnology platforms offer a new life for conventional pesticides, which improves bioavailability through different kinetics, mechanisms and pathways on their target organisms, thus enabling them to suitably bypass biological and other unwanted resistances and therefore increase their efficacy. This review is intended to serve the scientific community for research, development and innovation (RDI) purposes, by providing an overview on the current status of the host–guest supramolecular chemistry of nanopesticides, focusing on only the two-dimensional (2D), brucite-like inorganic layered hydroxides, layered hydroxide salts and layered double hydroxides as the functional nanocarriers or as the hosts in smart nanodelivery systems of pesticides for plant protection. Zinc layered hydroxides and zinc/aluminum-layered double hydroxides were found to be the most popular choices of hosts, presumably due to their relative ease to prepare and cheap cost. Other hosts including Mg/Al-, Co/Cr-, Mg/Fe-, Mg/Al/Fe-, Zn/Cr- and Zn/Cu-LDHs were also used. This review also covers various pesticides which were used as the guest active agents using supramolecular host–guest chemistry to combat various pests for plant protection. This looks towards a new generation of agrochemicals, “agro-nanochemicals”, which are more effective, and friendly to life, humans and the environment.

“…Moreover, pectin and alginate aerogels are promising candidates for impregnation of poorly water-soluble drugs in order to improve their bioavailability [ 10 ]. Furthermore, recent studies have shown that in order to prevent the rapid release of some drugs a more controlled release could be achieved by coating the gels [ 12 , 13 , 14 , 15 ]. Chitosan consists of 2-acetamide-2-deoxy-beta-D-glucopiranose and 2-amino-2-deoxy-beta-D-glucopirnose monomers linked together by 1,4-glycosidic bonds.…”

The presented study shows the possibility of using bioaerogels, namely neat alginate, pectin, chitosan aerogels, and alginate and pectin aerogels coated with chitosan, as drug delivery systems for esomeprazole. Two different techniques were used for the impregnation of esomeprazole: Supercritical impregnation, and diffusion via ethanol during the sol-gel synthesis. The prepared samples were characterized by employing N2 adsorption-desorption analysis, TGA/DSC, and FTIR. The achieved loadings were satisfactory for all the tested samples and showed to be dependent on the technique used for impregnation. In all cases, higher loadings were achieved when impregnation via diffusion from ethanol was used. Extensive release studies were performed for all impregnated samples. The in vitro dissolution profiles were found to be dependent on the carrier and impregnation method used. Most importantly, in all cases more controlled and delayed release was achieved with the bioaerogels compared to using pure esomeprazole.
