“…ZNPs were prepared by nanoprecipitation using an adapted version of a previously published synthesis protocol with two surfactants, DMAB and Tween 80 (Kacsó et al 2018). The organic phase was formed by dissolving 3778 mg of zein in 120 mL of an acetone-water [80:20 (v/v)] solution under magnetic stirring at room temperature.…”

“…Nanodelivery of agrochemicals is advantageous over conventional applications (Yang et al 2014), offering protection to the active compound against degradation, increased solubility, improved efficacy (Pereira et al 2017), controlled release, decreased toxicity of the agrochemical to non-target organisms (Pascoli et al 2018), and a low negative impact on soil microbiome (Ur Rahim et al 2021). Some PNPs provide the additional benefit of biodegradability over other types of nanodelivery systems (Kacsó et al 2018).…”

“…To better understand their environmental impact and role in seed protection and soybean plant development, this study focused on tracking PNPs in seeds after treatment and during germination while determining their effect on plant growth indicators, non-target pests (in this case, insects), and antifungal activity. Two PNPs, both ZNP and LNP, were chosen as the nanodelivery system due to their biodegradable nature (Kacsó et al 2018) and potential in agriculture (de Oliveira et al 2014;Ristroph et al 2017). Previous studies have shown an affinity of positively charged ZNPs for soybean roots grown in hydroponic conditions (Ristroph et al 2017).…”

Zein nanoparticles (ZNPs) were synthesized with a cationic surfactant, didodecyldimethylammonium bromide (122.9 ± 0.8 nm, + 59.7 ± 4.4 mV) and a non-ionic surfactant, Tween 80 (118.7 ± 1.7 nm, + 26.4 ± 1.1 mV). Lignin-graft-poly(lactic-co-glycolic) acid nanoparticles (LNPs) were made without surfactants (52.9 ± 0.2 nm, − 54.9 ± 0.5 mV). Both samples were applied as antifungal seed treatments on soybeans, and their impact on germination and plant health was assessed. Treated seeds showed high germination rates (> 90% for all treatment groups), similar to the control group (100%). Root and stem lengths and the dry biomass of treated seeds were not statistically distinguishable from the control. Foliage from seed-treated plants was fed to larvae of Chrysodeixis includens with no differences in mortality between treatments. No translocation of fluorescently tagged particles was observed with fluorescence microscopy following seed treatment and germination. Nano-delivered azoxystrobin provided ~ 100% protection when LNPs were used. Results suggest ZNPs and LNPs are safe and effective delivery systems of active compounds for seed treatments.

Tissue engineering (TE) is one of the most challenging fields of research since it provides current alternative protocols and materials for the regeneration of damaged tissue. The success of TE has been mainly related to the right selection of nano-sized biocompatible materials for the development of matrixes, which can display excellent anatomical structure, functionality, mechanical properties, and histocompatibility. Today, the research community has paid particular attention to zein as a potential biomaterial for TE applications and nanotechnological approaches. Considering the properties of zein and the advances in the field, there is a need to reviewing the current state of the art of using this natural origin material for TE and nanotechnological applications. Therefore, the goal of this review paper is to elucidate the latest (over the last five years) applications and development works in the field, including TE, encapsulations of drugs, food, pesticides and bandaging for external wounds. In particular, attention has been focused on studies proving new breakthroughs and findings. Also, a complete background of zein’s properties and features are addressed.

“…Obviously, by controlling the size of the carrier, e.g., between nano and micro size, it is possible adjust what can be inside the carrier but also to enhance or inhibit cellular internalisation [ 67 ]. Finally, the expiry date of the kill substance should be considered, i.e., the degradation rate of the kill material should be faster than that of the nanocarrier (when not triggered) as this will also help to prevent undesirable release of unused pesticide [ 68 ].…”

Nano-pesticides: the lunch-box principle—deadly goodies (semio-chemical functionalised nanoparticles that deliver pesticide only to target species)

Nature contains many examples of “fake promises” to attract “prey”, e.g., predatory spiders that emit the same sex-attractant-signals as moths to catch them at close range and male spiders that make empty silk-wrapped gifts in order to mate with a female. Nano-pesticides should ideally mimic nature by luring a target and killing it without harming other organisms/species. Here, we present such an approach, called the lunch-box or deadly-goodies approach. The lunch-box consists of three main elements (1) the lure (semio-chemicals anchored on the box), (2) the box (palatable nano-carrier), and (3) the kill (advanced targeted pesticide). To implement this approach, one needs to draw on the vast amount of chemical ecological knowledge available, combine this with recent nanomaterial techniques, and use novel advanced pesticides. Precision nano-pesticides can increase crop protection and food production whilst lowering environmental impacts. Graphical Abstract
