As an analytical instrument, spectrometers are used in almost every scientific field, especially in physical, chemical and biological research. This type of device is usually too bulky to move. Scientists have long devoted themselves to miniaturizing, low-cost, and easy-to-use spectrometers in order to increase their use. But all along, related efforts have not been very successful. According to the US MIT official website, this time, the former MIT postdoctoral researcher, Bao Jie of Tsinghua University in China, and Moji Barwandi, professor of chemistry at MIT, proposed that the design limitations of existing miniature spectrometers can be used. Colloidal quantum dots overcome quantum dots that are highly regulatable, miniature, and light-sensitive semiconductor crystals. Using quantum dots can reduce the size of the spectrometer without affecting its resolution, range of use, and efficiency. The researchers demonstrated a spectrometer made of 195 different quantum dots, each of which is sensitive to a specific spectral range, filtering light of various wavelengths and detecting very small spectral shifts. Wang Feng, associate professor of physics at the University of California, Berkeley, believes that this method, called "beautiful," uses semiconductor quantum dot microspectrometers to control light absorption. The device is small and has high performance. It has never been used before. Realized. The authors of the papers stated that this system combines high performance and simplicity with ease of manufacture and potential for further miniaturization, so it will greatly benefit those applications that need to be reduced in size, weight, cost, and complexity. . 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 used for labeling cells and biomolecules. It is also very useful in the field of computers and television displays. The delicate TV Mobile Stand with slim struction but loading weight up to 660 pounds, it is widely use for large size (70~120") TVs display and passed UL approval yet.
