Avermectin (AVM) as a nonsystemic pesticide possesses a low effective utilization rate. Studies of the multifunctional pesticide delivery system for improving biological activity are developing prosperously. In this study, multifunctional avermectin/polysuccinimide with glycine methyl ester nanoparticles (AVM-PGA) were prepared by the selfassembly process. The AVM loading capacity was up to 23.7%. After 24 h of UV irradiation, there was still about 70% of AVM remaining in PGA 42 nanocarriers, as opposed to less than 5% of the free-form AVM. The rising ambient pH promoted the release of AVM using an in vitro releasing test, revealing a favorable pH-responsively controlled-release property. The mortality rate of Plutella xylostella with 2.5 μg/mL of AVM content of AVM-PGA 42 was 96.3% after 48 h, while that of free AVM was only 51.5%. In addition, the AVM could be detected in stems and all leaves treated with AVM-PGA 42 nanoparticles, whereas rare AVM was detected only in treated leaves for the free-form AVM, which achieved the transportation of nanocarriers carrying AVM in rice for the first time. Furthermore, the PGA nanoparticles performed a good growth promoting effect on rice. These results show that the AVM-PGA 42 nanopesticides have a great potential application prospect to control the pest and improve the drug utilization efficiency on agriculture.

“…Carvacrol is one of the volatile phenolic constituents of oregano oil, which, during the process, evaporates from the film into the sorrounding. Once the outer membrane of the microorganism contacts the film, the physical structure of the bacteria cell wall is distorted and disintegrated (Hernández-González et al, 2017;Muriel-Galet et al, 2015). The strong inhibitory effect of OE has been discussed in other studies in the literature (Burt, 2004;Dadalioglu & Evrendilek, 2004;Gallo, Debeaufort, Callegarin, & Voilley, 2000;Hernández-González et al, 2017;Muriel-Galet et al, 2015).…”

“…However, the most effective antimicrobial and antifungal activators of oregano, which have frequently been mentioned in the literature, are carvacrol and thymol (Lukas, Schmiderer, Franz, & Novak, 2009). Interestingly, while it has widely been employed due to its antimicrobial impact (Hernández-González et al, 2017;Muriel-Galet et al, 2015;Sabino et al, 2018;Wang, Marcone, Barbut, & Lim, 2012), a few reports have concerned oregano to incorporate it into polysaccharide-based edible films (Wang et al, 2012).…”

Herein, Psyllium‐seed mucilage (PSM) and oregano extract (OE) were incorporated into the design of a promising, biodegradable, and antimicrobial edible film to enhance the shelf life of food. Various OE‐PSM films with different concentrations of OE, PSM, and glycerol, as a plasticizer, were fabricated. Further physicochemical, mechanical, and structural studies demonstrated an enhancement in the films' thickness, extensibility, and water‐related properties (excluding water vapor permeability [WVP]) by increasing the glycerol and OE content. Also, the final OE‐PSM films presented a bit yellow and opaque appearance. The effectiveness of fabricated films against microbial attacks was confirmed by the in vitro zone of inhibition measurement against Staphylococcus aureus and Escherichia coli, almost 118 and 77 mm, respectively. In addition, the efficiency of films on the extension of the postharvest lifetime of strawberries to 16 days was optically approved by determining the coated strawberries decay. All mentioned above confirmed the potential of the developed OE‐PSM as a promising edible film. Practical Application Recently, new technology and materials have prompted to meet the consumers' demand for healthier and safer food. To support this claim, we developed a productive edible film (plasticized OE‐PSM film) which showed acceptable biodegradability, mechanical stability, water resistance, and antimicrobial efficiency. The unique properties of this edible film have made it a promising film, which is not only potent to extend the shelf life of food products, leading to facilitate the commercialization activities, but also inexpensive and more available over the traditional synthetic ones. These properties turn this film to a productive candidate, deserve to be implemented by the food and agricultural industries.

“…The FTIR spectrum of PSI in Figure 3(f ) presents strong amide vibrations at 1712 cm −1 corresponding to C O stretching vibrations characteristic of cyclic imides, amide A (N─H stretching) at 3406 cm −1 and ~3608 cm −1 , amide II (N─H bending and C─N stretching) at 1540 cm −1 , and amide III (C─N wagging) between 1260 cm −1 and 1300 cm −1 , all of which are consistent with the results from González. 35 The N─H stretching vibrations in the spectra of PGMA-N-PSI were displaced to 3600 cm −1 , indicating that the PSI was grafted onto the surface of the microspheres. Thus it can be confirmed that the PGMA microspheres were modified with the PASP.…”

Novel macroporous, hydrophilic microspheres with a surface layer of crosslinked poly(aspartic acid) were synthesized. In this study, macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [poly(GMA-co-EGDMA)] microspheres with pore size around 370 nm were first obtained through the surfactant reverse micelle swelling method, and the poly(GMA-co-EGDMA) was aminated by ethylene diamine to form poly(GMA-NH 2 ). The polysuccinimide was grafted onto the surface of poly(GMA-NH 2 ) microspheres and crosslinked by hexamethylendiamine and γ-aminopropyltriethoxysilane, respectively, and then hydrolyzed to obtain the poly(aspartic acid)-functionalized macroporous microspheres. The functionalized hydrophilic microspheres were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis, mercury porosimetry, and elemental analysis. The metal ion adsorption capacity was also studied. The FTIR, XPS, and elemental analysis confirmed the poly(aspartic acid) functionalization of the poly(GMA-co-EGDMA) microspheres. SEM and mercury porosimetry showed there was little effect of this surface chemical modification on microsphere porosity, and the obtained macroporous microspheres exhibited excellent thermal stability and adsorption for Ag(I), presenting great potential for applications in adsorption, fixation, and separation.
