BACKGROUND The present work illustrates how magnetic separation-based blood purification using ultra-strong iron nanomagnets can be implemented into an extracorporeal blood purification circuit. By this promising technique, today's blood purification may be extended to specifically filter high-molecular compounds without being limited by filter cut-offs or column surface saturation. METHODS B...

Bioactive molecules (or signaling molecules) are involved in tissue regeneration and have an important role modulating the microenvironment vivo. chemicals ability to govern host cell motility, proliferation, differentiation, as well enabling cells interact with their surrounding via particular receptors for chemical recognition. This chapter introduces ion-exchange chromatography (IEC) a metho...
