The related paper has been published in the prestigious journal Nature.
It is known that spectroscopy is an instrument for analyzing light and color dispersion phenomena, and is an indispensable part of modern technology. Traditional spectroscopes are limited by their large size and high energy consumption, hindering their application in certain fields. Yang Zongying and his team used semiconductor nanomaterials to replace some components in traditional spectroscopes, achieving a compact size while maintaining high sensitivity and resolution. This has enabled single-cell high-spectral imaging, providing a new tool for biological and medical research, helping to analyze the structure and function of biological molecules.
The emergence of this spectroscope has attracted widespread attention from both domestic and foreign experts. Many in the field believe that this study represents a revolutionary breakthrough in spectroscopy, significantly advancing the development of the field. Meanwhile, single-cell high-spectral imaging has also opened up new opportunities for biological and medical research, providing a new means to analyze the structure and function of biological molecules.
It is understood that Yang Zongying and his team are currently working to further optimize the spectroscope’s structure and explore potential applications. With their compact size and high sensitivity, this spectroscope is expected to become an essential tool for researchers in the near future.
