Cellulose nanocrystals for crop protection: leaf adhesion and controlled delivery of bioactive molecules

Abstract

TA/Cu-XCM@βCNC nanocarrier is developed for crop protection, the introduced system enables pH-responsive controlled delivery, enhances deposition and prevents pesticide leakage.

Washout-Resistant, pH-Responsive Anti-TMV Nanoimmune Inducer Based on Cellulose Nanocrystals

“…Furthermore, CNC-loaded fenitrothion (XCM) is employed to enhance drug adhesion to leaves. Results indicate that upon spraying CNC@XCM onto leaves, the retention rate of XCM increases by 1.8 times, demonstrating superior antibacterial and insecticidal properties . Our laboratory has also used CNCs to desorb CTAB for the purpose of controlling Phycomycetes capsici.…”

“…Their biocompatibility, biodegradability, and drug encapsulation capabilities make them promising carriers, enhancing solubility, controlled release, and targeted delivery to improve therapeutic outcomes. , In agriculture, CNC’s potential shines as pesticide carriers . They effectively encapsulate and safeguard pesticides, extending stability, reducing environmental impact, and providing targeted pest delivery for efficient disease management. , Notably, recent studies have highlighted CNC’s role in improving drug adhesion and deposition on leaves. , For example, CNCs can serve as a carrier for loading thiamethoxam (TMX) to create nanopesticides capable of providing sustained TMX release. This application significantly enhances the insecticidal efficacy of TMX, with insecticidal rates ranging from 1.1 to 2.2 times higher than those of commercial insecticides .…”

Polystyrene/Polymethylhydrosiloxane Multiscale Electrospun Nanofiber Membranes for Air Filtration

“…Therefore, developing effective filters to remove PM from the air is imperative. Moreover, the biological safety of the material must be guaranteed . However, traditional filter materials, such as glass fiber, melt-blown nonwoven fabric, − and wood pulp fiber, have large fiber diameters (>1 μm) and large pore sizes.…”

“…Moreover, the biological safety of the material must be guaranteed. 3 However, traditional filter materials, such as glass fiber, 4 melt-blown nonwoven fabric, 5−7 and wood pulp fiber, have large fiber diameters (>1 μm) and large pore sizes. Therefore, their filtration processes rely on the electrostatic interception of particles, 8−10 resulting in high energy consumption and short lifespan.…”

Development of lignin-coated natural polysaccharide-based nanopesticides for both high foliar adhesion and rapid release of pesticide molecules against bacteriostasis

“…12 Similarly, Ning et al prepared pH-responsive controlled-release nano-pesticide with improved foliar adhesion by employing β-cyclodextrin and tannic acid modification. In addition to retention efficiency, 13 the cost and negative environmental impacts of pesticides are also significant factors that need to be considered during agricultural applications of pesticides. In this regard, biological macromolecules such as chitosan, 14–16 methylcellulose, 17 and lignin, 18,19 etc.…”
