    摘要: Method for making three-dimensional structures. A template is provided having at least two conductive regions separated by a non-conductive region. The template is disposed in an electrolyte in an electrodeposition cell and a voltage is established between one of the conductive regions and an electrode in the cell. Material is deposited on the one of the conductive regions connected to the voltage and subsequently bridges to the other conductive region with material deposition continuing on both of the at least two regions. The non conductive region may be a gap and the gap dimension is selected to regulate height differences between the at least two conductive regions.

    摘要: Acrylate-terminated poly(beta-amino esters) are cross-linked to form materials useful in the medical as well as non-medical field. The polymeric starting material is combined with a free radical initiator, either a thermal initiator or a photoinitiator, and the mixture for cross-linking is heated or exposed to light depending on the initiator used. The resulting materials due to the hydrolysable ester bond in the polymer backbone are biodegradable under physiological conditions. These cross-linked materials are particular useful as drug delivery vehicles, tissue engineering scaffolds, and in fabricating microdevices. The materials may also be used as plastics, coating, adhesives, inks, etc. The cross-linked materials prepared exhibit a wide range of degradation times, mass loss profiles, and mechanical properties. Therefore, the properties of the material may be tuned for the desired use. The high-throughput approach to preparing a library of cross-linked poly(beta-amino esters) allows for the rapid screening and design of degradable polymers for a variety of applications.

    摘要: A new class of poly(beta-amino alcohols) (PBAAs) has been prepared using combinatorial polymerization. The inventive PBAAs may be used in biotechnology and biomedical applications as coatings (such as coatings of films or multilayer films for medical devices or implants), additives, materials, excipients, non-biofouling agents, micropatterning agents, and cellular encapsulation agents. When used as surface coatings, these PBAAs elicited different levels of inflammation, both in vitro and in vivo, depending on their chemical structures. The large chemical diversity of this class of materials allowed us to identify polymer coatings that inhibit macrophage activation in vitro. Furthermore, these coatings reduce the recruitment of inflammatory cells, and reduce fibrosis, following the subcutaneous implantation of carboxylated polystyrene microparticles. These polymers may be used to form polyelectrolyte complex capsules for cell encapsulation. The invention may also have many other biological applications such as antimicrobial coatings, DNA or siRNA delivery, and stem cell tissue engineering.
