Abstract: Photoreceptor scaffolds and scaffold systems including the photoreceptor scaffolds are described herein. The scaffolds and scaffold systems can be used for transplantation of organized photoreceptor tissue, with or without RPE, which may improve grafted cell survival, integration, and functional visual rescue. Particularly, the photoreceptor scaffold is structured from a biocompatible film, patterned with an array of unique through-holes having a curvilinear cell receiver and at least one cell guide channel.

Abstract: Stretchable high frequency transmission lines and high-frequency filters comprising the transmission lines are provided. The transmission lines provide low power loss, even at microwave and millimeter wave frequencies. The transmission lines are thin and flexible and can be stretched without a significant degradation of their scattering parameters. As a result, the transmission lines have applications as interconnects in stretchable and flexible integrated circuits (IC) and circuit device components, such as flexible transistors and flexible diodes.
