Description

technical field [0001] The invention relates to a method for preparing a carrier material that can be used for fixing biological samples, in particular to a method for preparing a high-density nanoporous glass-ceramic / glass carrier material. Background technique [0002] The 21st century is the century of life sciences, and the application of biotechnology in medical diagnosis has gradually matured. At the same time, related biological and chemical device technologies have also been developed rapidly, such as biosensors, bioinformatics, and chemical sensors. However, how to study the functions of so many genes and proteins in the life process has become a common topic for life science workers all over the world, and it is against this background that biochips emerged. [0003] Since the beginning of the 1990s, some countries, mainly the United States, began to develop various biochips. In less than ten years, biochip technology has developed ra...
