Thesemolecular recognition functions can be combined with the target, such as the binding of antibodies and antigens, and thebinding of enzymes to the substrate through the recognition process. Biosensor has the advantages of high specificity,high sensitivity, fast reaction speed, low cost and easy operation. It has wide application prospect in food, pharmacy,chemical industry, clinical examination, biomedicine, environmental monitoring and so on, especially as a newtechnology means, in the field of modern herbal medicine research influence. Studies have demonstrated that thebiosensing technology has been applied to, traditional Chinese medicine （TCM） targets, isolation and purification ofTCM, the mechanism of TCM, quality control of TCM, the active ingredients detection of TCM and other basicresearches. Biosensor technology has made an important contribution to the research of modern herbal medicine, and hasbecome a Hot-spot in future research.展开更多

The production and the supply of high quality laboratory animals have fundamental importance for the accomplishment of vanguard scientific research, with reproducibility and universality. The quality of those animals depends, largely, on the available facilities for their production and lodging, to assure the demanded sanitary control and animal＇s welfare, in agreement with the ethical principles that control the activity. Therefore, the facilities design is of vital importance so that the mentioned requirements can be reached. Nevertheless, pigs and miniature pigs have gained importance as large animal models in medicine. With their size, organ capacity, and physiology resembling in several aspects that of humans, pigs are well suited for preclinical experiments and long-term safety studies. Minipigs will be used for preclinical testing of radiopharmaceuticals and assays radioactive materials for cardiac tests. This paper describes the premises and preliminary activities that have been performed at IPEN for the design of new Animal House Facilities dedicated to keeping minipigs taking into account fundamental aspects such as： animal＇s welfare, sanitation, genetic, in agreement with the ethical principles that control the activity and environmental concerns.展开更多
