“…Further observation showed that NPs can penetrate the seed coat and enter the seed easily (Fig. ) so that the bioactivities of activator proteins were enhanced, results that are in accordance with previous studies . Hence, we assumed that our P@NPs entered the seed with high loading of activator protein PeaT1, which may then release the proteins continuously within the seeds to induce the expression of genes responsible for plant growth.…”

BACKGROUND Developing new types of bioproducts using innovative nanotechnology is one of the potentially effective options for enhancing agricultural production and reducing environmental agrochemical pollution. As a bioagent derived from fungi, activator protein can promote growth and control diseases by activating the plant immune system. Meanwhile, the nanocarrier can protect the protein within and prolong its efficiency through controlled release. RESULTS In our study, a new kind of plant nano‐activator was developed by encapsulating an activator protein PeaT1 using a polymer nanoparticle constructed with monomethoxy‐poly (ethylene glycol)‐poly (lactide‐co‐glycolide) (mPEG‐PLGA). The nanoparticles were spherical with diameter about 200 nm. Morphological and physiological parameters of wheat seedlings, including seed vigor index, root vitality, chlorophyll content and photosynthetic parameters, increased after treatment with the nano‐activator. Further observation under the confocal laser microscope showed a more effective intake of the nano‐activator protein. CONCLUSION The results showed that the nano‐activators are effective in enhancing wheat growth. This novel agent provides a promising way to improve crop production in an environmentally friendly manner. © 2018 Society of Chemical Industry

“…Chitosan-polyacrylic acid nanoparticles were found to be fungi-sensitive with a decrease of inhibition percentage as follows: Aspergillus flavus (60%), Fusarium oxysporum (41%), Fusarium solani (40%), Aspergillus terreus (40%), Alternaria tenuis (40%), Aspergillus niger (37%), and Sclerotium rolfsii [41]. The antimicrobial activity of nano-chitosan compared to its bulk counterpart on Pyricularia grisea, Alternaria solani and Fusarium oxysporum was investigated [43]. The nanochitosan exhibited higher percentage inhibition of the mycelia growth compared to bulk chitosan.…”

The rise in the World’s food demand in line with the increase of the global population has resulted in calls for more research on the production of sustainable food and sustainable agriculture. A natural biopolymer, chitosan, coupled with nanotechnology could offer a sustainable alternative to the use of conventional agrochemicals towards a safer agriculture industry. Here, we review the potential of chitosan-based agronanochemicals as a sustainable alternative in crop protection against pests, diseases as well as plant growth promoters. Such effort offers better alternatives: (1) the existing agricultural active ingredients can be encapsulated into chitosan nanocarriers for the formation of potent biocides against plant pathogens and pests; (2) the controlled release properties and high bioavailability of the nanoformulations help in minimizing the wastage and leaching of the agrochemicals’ active ingredients; (3) the small size, in the nanometer regime, enhances the penetration on the plant cell wall and cuticle, which in turn increases the argochemical uptake; (4) the encapsulation of agrochemicals in chitosan nanocarriers shields the toxic effect of the free agrochemicals on the plant, cells and DNA, thus, minimizing the negative impacts of agrochemical active ingredients on human health and environmental wellness. In addition, this article also briefly reviews the mechanism of action of chitosan against pathogens and the elicitations of plant immunity and defense response activities of chitosan-treated plants.

“…The control of diseases caused by these microorganisms is a problem that remains unsolved (Cota-Arriola O. et al, 2013). To protect crops from fungal pathogens, the growth of the fungi can be inhibited by using proteinchitosan nanoparticle conjugate as demonstrated by Sathiyabama M. and Parthasarathy R. (2016). The chitosan nanoparticle was prepared through the biological method by the addition of anionic proteins to the chitosan solution.…”

In the past few decades, enormous advances have been achieved in the field of particle technology and the trend has been shifted from macro to micro and recently to the nanoscale. Integration of nanotechnology and biotechnology has paved the way to the development of biological nanoparticles, derived from biomolecules, and biomolecule-nanoparticle conjugates for numerous applications. This review provides an overview of various types of biological nanoparticles and the methods of their fabrication with primary emphasis on the drying methods, particularly on the newly emerging technique, the electrospraying. Recent advances in the integration of biomolecules with nanoparticles in the past five years to present are also discussed. Finally, the application of the biomolecule-nanoparticle conjugates in various fields including medicals and pharmaceuticals, biosensors and bioelectronics, foods, and agricultures are also highlighted.
