Encapsulation, biomaterials

The main advantage is that the entrapment conditions are dictated by the entrapped enzymes, but not the process. This includes such important denaturing factors as the solution pH, the temperature and the organic solvent released in the course of precursor hydrolysis. The immobilization by THEOS is performed at a pH and temperature that are optimal for encapsulated biomaterial [55,56]. The jellification processes are accomplished by the separation of ethylene glycol that possesses improved biocompatibility in comparison with alcohols. [Pg.101]

Biomaterials are inert substances that are used in contact with living tissue, resulting in an interface between living and non-living substances [45,46], Biocompatibility of this interface is achieved by using such biomaterials for encapsulation in the construction of sensor devices. [Pg.293]

The interaction in an interface of device/tissue is limited by two factors. There is the corrosive environment, such as biological fluid, which contains salts and proteins among other cellular structures in which the sensor device must survive [47, 48], Second, there is the encapsulation material which may induce a toxic reaction due to poor biocompatibility and hemocompatibility [49, 50], It is crucial to use a biomaterial that can overcome both limiting factors to maintain the lifetime of the sensor device and protect the body [51, 52],...

Another area where polymers are making a significant difference in nerve regeneration is the use of polymers to encapsulate and release trophic factors, or encapsulate cells that release nerve growth factor or other agents that enhance the regeneration process. This chapter details the advances in the use of polymeric biomaterials that have been explored for nerve regeneration in the peripheral and central nervous systems. [Pg.48]

It is often demanded that the surface of polymeric biomaterials should exhibit permanent tenacious adhesion to soft connective and dermal tissues. However, conventional non-porous, polymeric materials will be encapsulated by a fibrous membrane generated de novo by surrounding fibroblasts, when subcutaneously implanted into the living body in contact with soft connective tissues. This is a typical foreign body reaction of the living system to isolate foreign materials from the host inside the body. On the other hand, it should be noted that the small gap present between a percutaneously-implanted device and the surrounding tissue provides a possible route for bacterial infection because of the lack of microscopic adhesion at the interface.
