Negatively Charged Carbon Dots Employed Symplastic and Apoplastic Pathways to Enable Better Plant Delivery than Positively Charged Carbon Dots

ACS Nano, Год журнала: 2024, Номер 18(34), С. 23154 - 23167

Efficient delivery of nanoparticles (NPs) to plants is important for agricultural application. However, date, we still lack knowledge about how NPs' charge matters its translocation pathway, i.e., symplastic and apoplastic pathways, in plants. In this study, synthesized used negatively charged citrate sourced carbon dots (C-CDs, −37.97 ± 1.89 mV), Cy5 coated C-CDs (Cy5-C-CDs, −41.90 2.55 positively PEI (P-CDs, +43.03 1.71 P-CDs (Cy5-P-CDs, +48.80 1.21 mV) investigate the role surface charges coatings on employed pathways (symplastic pathways) NPs Our results showed that, different from higher fluorescence intensity Cy5-P-CDs extracellular than intracellular space, Cy5-C-CDs was similar between space cucumber cotton roots. It suggests that CDs were translocated via both but mainly pathway. Furthermore, our root applied demonstrated leaf did (8.09 0.99 vs 3.75 0.23) (7.27 1.06 3.23 0.22), indicating have a efficiency do CDs. should be noted not affect cell activities, ROS level, photosynthetic performance cotton, showing good biocompatibility. Overall, study only figured out transportation roots compared with employment pathway CDs, also found could more efficiently imparting negative NPs, at least efficient crops.

Mechanism of Nanomaterial-Induced Lipid Droplet Formation in Raphidocelis subcapitata is Mediated by Charge Properties

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2025, Номер unknown

Опубликована: Фев. 12, 2025

Abstract Increasing the production of renewable energy will be critical to achieving global sustainability goals in coming decades. Biofuels derived from microalgae have great potential contribute this production. However, cultivating algae with sufficient neutral lipid content, while maintaining high growth rates, is a continual challenge making algal-derived biofuels reality. Previous work has shown that exposure polymer-functionalized carbon dots can increase content Raphidocelis subcapitata . This study investigates finding, aiming determine mechanisms underlying effect and if altering nanoparticle surface charge mediates mechanism action used. Carbon both negative positive charges were added microalgal cultures, impacts analyzed using high-content imaging, measurements, chlorophyll measurements. Results indicate positively charged induce nano-specific but also cause decreases growth. Additionally, each was examined by conducting morphological comparison known treatments. analysis showed negatively similar R. as nitrogen deprivation, which droplet increased. The findings suggest may dependent effects on metabolism Future should consider use varied densities for enhancing biofuel bioreactors.

Nanocarrier mediated delivery of insecticides into tarsi enhances stink bug mortality

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Ноя. 11, 2024

Current delivery practices for insecticide active ingredients are inefficient with only a fraction reaching their intended target. Herein, we developed carbon dot based nanocarriers molecular baskets (γ-cyclodextrin) that enhance the of into insects (southern green stink bugs, Nezara viridula L.) via tarsal pores. feeds on leguminous plants worldwide and is primary pest soybeans. After two days exposure, most ingredient cargo (>85%) remained soybean leaf surface, rendering them available to insects. The enter bugs through tarsi, enhancing fluorescent chemical by 2.6 times. nanoformulation (10 ppm) was 25% more effective in controlling than alone. Styletectomy experiments indicated improved efficacy due entering insect pores, consistent assays. This new nanopesticide approach offers efficient integrated management sustainable agriculture.
