    Abstract
    Organic semiconductors are being increasingly used for a variety of biological applications, such as biochemical sensors, drug delivery, and neural interfaces. However, the poor adhesion of cells to the typically hydrophobic, neutrally charged and low surface energy of semiconducting thin films limit their use in in vitro, cell integrated bioelectronic devices. In this work, we investigate the influence of lysine side chain units incorporated in a diketopyrrolopyrrole (DPP) semiconducting polymer on neural cell adhesion and growth, as well as evaluate their function in electrical devices. Synthesis of such biofunctionalized polymers obviates the need of biological coating steps while changing the surface physiochemistry, promising for applications in bioelectronics.

    Export search results

    The export option will allow you to export the current search results of the entered query to a file. Different formats are available for download. To export the items, click on the button corresponding with the preferred download format.

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items. For anonymous users the allowed maximum amount is 50 search results.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
