What are the types of pesticide bioanalysis methods?
There were several main methods for pesticide bioanalysis: 1. ** Biological test (bacteria, fungi, viruses)**: It is one of the general analytical methods for the determination of active ingredients in pesticide products. It is used to determine the content of active ingredients in pesticide products. 2. ** Immune sensor technology **: It uses the highly specific immune reaction between the protein and the protein to detect the pesticide. In the immune sensor, an appropriate receptor was selected as the specific recognition element of the biological material. Through the specific antigen-receptor interaction, the target pesticide was selectively captured. The surface of the sensor was coated with a specific serum. When the target pesticide was present in the sample, the serum and the pesticide combined to form an antigen-serum complex, causing the sensor signal to change. This immune reaction made the detection have excellent sensitivity and sensitivity. 3. ** Biosensor technology **: This is a commonly used biosensor technology. Using the specific reaction between the reagent and the pesticide to achieve accurate detection of the pesticide, the appropriate reagent was selected as the specific recognition element of the biological material. The specific reaction between the reagent and the target pesticide led to the conversion of the catalyst, which then generated a measurement signal. Due to the high efficiency and the high sensitivity of the reaction, it had excellent sensitivity and fast response to pesticide detection in complex samples. 4. ** Molecularly imprinted sensor technology **: It is an emerging sensor technology that uses molecular imprinting technology to achieve highly specific recognition of pesticide. The molecular imprinting technique was a method of using target molecules and functional molecules to form a template. 5. ** Laboratory test method **: Under man-made control, such as temperature, humidity, light, host plant, insect age and density. Using agricultural pests or stored grain pests as test materials, the effects of various pesticide samples on stomach toxicity, contact toxicity, internal absorption, steaming and deterring effects were determined by droplet settling, leaf entrapment, tissue injection, or direct feeding, dipping, spraying, spraying, and local application. 6. ** Field test method **: It should be combined with the actual control, and the test plan should be carefully designed according to the purpose and requirements of the test, such as the comparison test of pesticide varieties and different dosage forms, the comparison test of dosage, concentration, time and frequency of application, etc. The field test was divided into small area test, large area test and large-scale demonstration test. The pesticide samples proved to be effective by indoor test were first tested in small area to determine the samples with better efficacy. Then, the large area test was used to further confirm its effectiveness and promotion value. Before a pesticide was officially promoted, it was necessary to carry out multi-point large-scale demonstration test. Read more exciting novels for free
