Fabrication, Characterization, and Biological Activity of Avermectin Nano-delivery Systems with Different Particle Sizes

Nano-delivery systems for the active ingredients of pesticides can improve the utilization rates of pesticides and prolong their control effects. This is due to the nanocarrier envelope and controlled release function. However, particles containing active ingredients in controlled release pesticide formulations are generally large and have wide size distributions. There have been...

Preparation and Characterization of Emamectin Benzoate Solid Nanodispersion

The solid nanodispersion of 15% emamectin benzoate was prepared by the method of solidifying nanoemulsion. The mean particle size and polydispersity index of the solid nanodispersions were  nm and , respectively. The high zeta potential value of  mV and stable crystalline state of the nanoparticles suggested the excellent physical and chemical stabilities. The contact angle and...

The Application of Nano-TiO2 Photo Semiconductors in Agriculture

Nanometer-sized titanium dioxide (TiO2) is an environmentally friendly optical semiconductor material. It has wide application value in many fields due to its excellent structural, optical, and chemical properties. The photocatalytic process of nano-TiO2 converts light energy into electrical or chemical energy under mild conditions. In recent years, the study and application of...

Stability and Biological Activity Evaluation of Chlorantraniliprole Solid Nanodispersions Prepared by High Pressure Homogenization

Poorly water-soluble compounds are difficult to develop as pesticide products and face great challenges in water-based and environmentally friendly formulation development. In this study, high pressure homogenization combined with lyophilization was adopted to prepare the solid nanodispersions of chlorantraniliprole with poor solubility and high melting point. The mean particle...

Preparation and Evaluation of Emamectin Benzoate Solid Microemulsion

The solid microemulsions of emamectin benzoate with the same content of surfactants were prepared by a self-emulsifying method. Emulsifier 600# and emulsifier 700# (3/2, w/w) screened from eleven kinds of commonly used surfactants displayed great emulsifying properties. The redispersed solution of the solid microemulsion presented aqueous microemulsion characteristic. The mean...

Construction and evaluation of controlled-release delivery system of Abamectin using porous silica nanoparticles as carriers

Photolysis and poor solubility in water of Abamectin are key issues to be addressed, which causes low bioavailability and residual pollution. In this study, a novel hydrophilic delivery system through loading Abamectin with porous silica nanoparticles (Abam-PSNs) was developed in order to improve the chemical stability, dispersity, and the controlled release of Abamectin. These...

Evaluation of Stability and Biological Activity of Solid Nanodispersion of Lambda-Cyhalothrin

Pesticides are essential agrochemicals used to protect plants from diseases, pests and weeds. However, the formulation defects of conventional pesticides cause food toxicity and ecological environmental problems. In this study, a novel, efficient and environmentally friendly formulation of lambda-cyhalothrin, a solid nanodispersion, was successfully developed based on melt...

A Magnetic Nanoparticle-Based Multiple-Gene Delivery System for Transfection of Porcine Kidney Cells

Superparamagnetic nanoparticles are promising candidates for gene delivery into mammalian somatic cells and may be useful for reproductive cloning using the somatic cell nuclear transfer technique. However, limited investigations of their potential applications in animal genetics and breeding, particularly multiple-gene delivery by magnetofection, have been performed. Here, we...

Study on performance of magnetic fluorescent nanoparticles as gene carrier and location in pig kidney cells

We evaluated the performance of green fluorescent magnetic Fe3O4 nanoparticles (NPs) as gene carrier and location in pig kidney cells. When the mass ratio of NPs to green fluorescent protein plasmid DNA reached 1:16 or above, DNA molecules can be combined completely with NPs, which indicates that the NPs have good ability to bind negative DNA. Atomic force microscopy (AFM...

Morphology, Structure and Function Characterization of PEI Modified Magnetic Nanoparticles Gene Delivery System

Modified magnetic nanoparticles are used as non-viral gene carriers in biological applications. To achieve successful gene delivery, it is critical that nanoparticles effectually assemble with nucleic acids. However, relatively little work has been conducted on the assemble mechanisms between nanoparticles and DNA, and its effects on transfection efficiency. Using biophysical and...

Application of PEI-Modified Magnetic Nanoparticles as Gene Transfer Vector for the Genetic Modification of Animals

To evaluate the performance of the magnetic nanoparticles as gene transfer vector for breeding transgenic animals, we investigated a new approach to deliver green fluorescent protein (GFP) gene to porcine kidney 15 (PK-15) and porcine embryonic fibroblast (PEF) cells using PEI-modified magnetic nanoparticles as gene vector. The morphology of the nanoparticles and nanoparticle/DNA...
