| 摘要 |
This invention relates to biologically-active polymers that are useful for analyte detection and isolation and delivery of substances. The biologicallyactive 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.
