“…MPN complexes have also been applied as preservatives for more complex, multicellular biological objects by forming nanometer-scale thin coatings on a range of fruits with spray-assisted coating method (83). The coating process was carried out by dissolving ferric chloride and TA in deionized water, and the solutions were sprayed with airbrush at a pressure of 10.5 liters/min.…”

Nanobiohybrids, synthesized by integrating functional nanomaterials with living systems, have emerged as an exciting branch of research at the interface of materials engineering and biological science. Nanobiohybrids use synthetic nanomaterials to impart organisms with emergent properties outside their scope of evolution. Consequently, they endow new or augmented properties that are either innate or exogenous, such as enhanced tolerance against stress, programmed metabolism and proliferation, artificial photosynthesis, or conductivity. Advances in new materials design and processing technologies made it possible to tailor the physicochemical properties of the nanomaterials coupled with the biological systems. To date, many different types of nanomaterials have been integrated with various biological systems from simple biomolecules to complex multicellular organisms. Here, we provide a critical overview of recent developments of nanobiohybrids that enable new or augmented biological functions that show promise in high-tech applications across many disciplines, including energy harvesting, biocatalysis, biosensing, medicine, and robotics.

“…7,15 In contrast, the influence of such parameters on the interfacial assembly of MPNs and the properties of the films formed via spray coating remain to be more thoroughly investigated. 24 Furthermore, other potential applications of spray-assembled MPNs based on different building blocks, i.e., combinations of different phenolic ligands and metals, are yet to be explored.…”

Hybrid conformal coatings-such as metal-phenolic networks (MPNs) that are constructed from the coordination-driven assembly of natural phenolic ligands-are of interest in areas including biomedicine, separation, and energy. To date, most MPN coatings have been prepared by immersing substrates in solutions containing the phenolic ligands and metal ions, which is a suitable method for coating small or flexible objects. In contrast, more industrially relevant methods for coating and patterning large substrates, such as spray assembly, have been explored to a lesser extent toward the fabrication of MPNs, particularly regarding the effect of process variables on MPN growth. Herein, a spray assembly method was used to fabricate MPN coatings with various phenolic building blocks and metal ions, and their formation and patterning were explored for different applications. Different process parameters including solvent, pH, and metal-ligand pair allowed for control over the film properties such as 2 thickness and roughness. Based on these investigations, a potential route for the formation of spray-assembled MPN films was proposed. Conditions favoring the formation of bis complexes could produce thicker coatings than those favoring the formation of mono or tris complexes. Finally, the spray-assembled MPNs were used to generate superhydrophilic membranes for oil-water separation and colorless films for UV shielding. The present study provides insights into the chemistry of MPN assembly and holds promise for advancing the fabrication of multifunctional hybrid materials.

“…Also, recent studies have focused on producing a safe, edible nano-coating to extend the shelf-life of fruits and vegetables. The nano-coating can be applied by spraying, dipping, brushing or panning the produce (Park et al, 2017). Such coatings can be used as antimicrobial and antioxidant layers, to prevent moisture absorption, and even as an added flavour to enhance food quality and stability (Debeaufort et al, 1998;Min and Krochta, 2005).…”

A reduction in crop spoilage and an increase in shelf-life is the goal of effective disease control methods. This study aimed to assess ZnO-nanoparticles (ZnO-NPs) as a safe, new protectant against Rhizopus soft rot of sweet potato. ZnO-NPs had a fungicidal effect against Rhizopus stolonifer when used at concentrations above 50 ppm. The results showed that tubers treated with ZnO-NPs exhibited fewer fungal populations (1.2 CFU per segment) than those that did not receive the treatment. Tubers infected with Rhizopus stolonifer and treated with ZnO-NPs showed no visible decay for up to 15 days, indicating that ZnO-NPs act as a coating layer on tuber surface. The greatest weight loss after 15 days of storage was reported in infected tubers (8.98%), followed by infected tubers treated with ZnO (6.54%) and infected tubers treated with ZnO-NPs (3.79%). The activity of cell-wall degrading enzymes, α-amylase and cellulase, were significantly increased in both infected tubers and those treated with ZnO, compared to the tubers treated with ZnO-NPs. These results confirm that coating with ZnO-NPs is an effective method of protecting sweet potato tubers from infection, maintaining their quality and increasing their shelf-life for up to 2 months in storage.Ke y wo r d s: edible coating, Rhizopus soft rot, shelf-life, sweet potato, ZnO-nanoparticles
