One of the chemists' recent achievements paved the way for a higher performance spectrometer that would be a miniature than the image sensor of a cellphone camera lens. A paper published in the January 1 issue of Nature in the United Kingdom described in detail a miniature quantum dot spectrometer for future applications including space exploration, personalized medicine, and microfluidic lab diagnostic platforms. As an analytical instrument, spectrometers are used in almost every scientific field, especially in physics, chemistry and biology. Such devices are often too bulky to move. Scientists have long been committed to miniaturizing spectrometers, being inexpensive and easy to use in order to increase their use. However, all these efforts have not been very successful. Quantum dot spectrometer equipment is printing the filter (schematic) According to the official website of the Massachusetts Institute of Technology, this time, the postdoctoral fellow at Massachusetts Institute of Technology, Bao Jie at Tsinghua University in China and Mok Bambadi, a chemistry professor at MIT, proposed that the design limitations of existing micro-spectrometers could be used The quantum dot is overcome by the colloidal quantum dots, which are height-adjustable, miniature and light-sensitive semiconductor crystals. The use of quantum dots can reduce the spectrometer volume without affecting its resolution, use range and efficiency. Researchers showed a spectrometer made of 195 different quantum dots, each of which is sensitive to a specific spectral range, filters light of various wavelengths and detects very small spectral shifts. Wang Feng, an associate professor of physics at the University of California, Berkeley, believes this is a "beautiful" way to control light absorption using semiconductor QDs. The device's small size and high performance have never before Achieved. The authors said the system combines high performance and simplicity with ease of manufacture and the potential for further miniaturization, which will be largely beneficial to applications that require reduced size, weight, cost, and complexity . When combined with small devices, it can be used to diagnose skin conditions or analyze urine samples, and even to track vital signs such as pulse and blood oxygen levels. At the same time, this research also represents a new application of quantum dots. This nanostructured material is now mainly suitable for labeling cells and biomolecules and is also of great use in the field of computer and television displays. Chief editor punctuality Quantum dots These nanocrystals, discovered in the 1980s, have well-known absorption properties and are very stable. Now taking advantage of the inherent nature of the quantum dots to create the benefits of the new spectrometer, and even small enough to run on a smartphone, makes a once bulky laboratory device easy to walk into everyday life. Benefit from not only scientists to study the atomic energy level, the analysis of biological tissue samples, more industries are free to use spectrometers, such as detecting environmental pollution, judging food safety and so on.
