自本世纪七十年代以来,酶和细胞的固定化技术一直是生物技术中最活跃的领域之一。 酶的固定化技术的研究始于六十年代中期,至今已有20余年的历史。从图1的统计数据不难看出,七十年代中至八十年代初是该领域研究工作发展最快的时期。八十年代开始,每年约发表1000篇以上的文献和近200篇专利。人们探索和研究过的固定化方法已达100 Immobilization of enzymes and cells has been one of the most active areas in biotechnology since the 1970s. Enzyme immobilization technology began in the mid-1960s, has been more than 20 years of history. As can be seen from the statistics in Figure 1, the mid-1970s and early 1980s were the fastest-growing period of research work in this area. Since the 1980s, more than 1,000 articles and nearly 200 patents have been published each year. The method of immobilization that people have explored and studied has reached 100
