| 摘要 |
This invention relates to biologically-active polymers that are useful for analyte detection and isolation and delivery of substances. The biologically-active polymers are capable of specifically and reversibly binding to analytes, including molecules and cells. The biologically-active polymers are also capable of releasing substances upon electrical stimulation. The present invention provides compositions comprising biologically-active polymers membranes and methods for making these biologically-active polymers membranes that may be specifically designed to selectively bind cells and specific cell types, to affect cell growth characteristics, and to modulate cellular differentiation. These biologically-active polymers membranes may be controlled electrically to induce controlled cellular differentiation and modulate the cell growth cycle. These biologically-active polymers have many applications in biological and chemical fields.
