Russia, St Petersburg University of science and technology news release, the school's researchers found a new biological analysis method, the use of laser pointerspectral signals to measure the size of nano and micron particles in liquid. With this, the research results can be used in medical research of liquid sample analysis, environmental monitoring and liquid technology testing and other fields. The new method has obvious advantages compared with the analysis method of the present practical application.
The new method is more accurate than the traditional method for the measurement of the size of the particles in the liquid, and the accuracy of the component in the liquid can be increased by 20-60%. Prior to this, laser spectroscopy technology can only be used to measure the same size of particles in the liquid and the application of the technology is greatly limited, St Petersburg University of science and technology scientists have exceeded this limit.
In the research of green laser pointer spectral information analysis, research results of the Soviet mathematician and physicist Andre Tikhonov - Tikhonov regularization method based on the School researchers have tried a variety of methods and eventually found a new fast calculation method of nonlinear system, so that the calculation speed of the particle size increase. Even in the coexistence of a variety of groups of particles in the liquid, the method can ensure the accuracy of the calculation is accurate enough. At present, the biological analysis method has been related patents, the research team will be introduced into the practical application as soon as possible.
