High-sensitivity detection of live samples of Cd2 + from the US "Non-damage Micro-measurement Technology Center"

The “Non-damage Micro-Measurement Technology” test center established by American younger company in Xuyue (Beijing) Technology Co., Ltd. has successfully used the “Non-damage Micro-measurement Technology” for rice, Chlamydomonas and other Cd2 + since the official launch of Cd2 + detection of live samples Absorption research provides services for the first time in China to achieve high sensitivity (10-12 power per square centimeter per second) and high repeatability detection of Cd2 + absorption of living samples. Based on the advantages of "non-damage micro-measurement technology", we can detect the concentration, rate, movement direction and other information of Cd2 + in and out of the sample without contacting the sample. In addition to the whole plant, "non-damage micro-measurement technology" also Can be tested at the level of organelles (such as chloroplasts, mitochondria, etc.), single cells (such as Chlamydomonas single cells), tissues, organs (such as roots, stems, leaves, etc.). The test center provides free observation and test opportunities. Welcome teachers and students to come to understand and try, and discuss the application of the technology in related fields.

At present, we have assisted many universities and research institutes to carry out scientific research. The types of ions / molecules tested include H +, Ca2 +, K +, Na +, Cl-, Cd2 +, NH4 +, NO3-, H2O2, O2, etc. welcome. They bring samples to the company for testing, and only need to pay a limited fee, they can get a lot of data, and quickly obtain the materials needed for publishing articles. If you are interested in "non-damage micro-measurement technology", please contact us, or log in "Technical Forum" (http: //), "non-damage micro-measurement technology" engineers can communicate with you at any time.

Cd2 + is a hot topic in the research of phytoremediation technology, but the principle of plant response to Cd2 + is still unclear. In addition to some routine research, people can now use "non-damage micro-measurement technology" to conduct research, which can monitor the absorption of Cd2 + by plants in real time in the plant's physiological environment. Miguel A. Pineros and Jon E. Shaff of the American Plant, Soil and Nutrition Laboratory and the Department of Agronomy [1] used "non-damaging micro-measurement technology" in "Plant Physiol" [2] to study the blue roots and wheat root The absorption of heavy metals Cd2 + indicates that the technology has unique advantages in studying the response and mechanism of plants to cadmium under environmental pollution conditions.
