1264927/1264948Kymissis/MaThis program will develop a new platform for biophotonics using thin film organic semiconductor materials capable of generating and detecting light in a thin, flexible form factor. The proposed architecture overcomes both the limitations of previously demonstrated implantable systems, as well as the challenges (environmental stability and device cross-coupling) traditionally associated with thin film systems. They will build a series of blood flow monitors using flexible organic light emitting diodes (OLEDs) and organic photodetectors (OPDs) to map both oxygenation and total hemoglobin in the brain, increasing in size, scale, and complexity as the program progresses. They will demonstrate the functionality and stability of the systems using both simulated condition testing and implanted devices. This platform applies OLED technology, which has had a significant impact in displays, to build a transformative light source for biological research that is capable of implantation in nearly any configuration and can be used to image reflectance and fluorescence over large areas for extended periods of time. This thin, flexible platform can bring this new perspective and capability to a broad class of imaging, optogenetic, fluorescence measurement, and other biophotonic applications.This award is co-funded by the IDBR program (Instrument Development for Biological Research) in the BIO Directorate, and Biophotonics program in the Engineering Directorate.

1264927/1264948Kymissis/Ma该项目将使用薄膜有机半导体材料开发一个新的生物光子学平台，能够以薄而灵活的形式产生和检测光。所提出的架构克服了先前演示的可植入系统的局限性，以及传统上与薄膜系统相关的挑战（环境稳定性和设备交叉耦合）。他们将使用柔性有机发光二极管 (OLED) 和有机光电探测器 (OPD) 构建一系列血流监测器，以绘制大脑中的氧合和总血红蛋白图，随着项目的进展，监测器的尺寸、规模和复杂性也会不断增加。他们将使用模拟条件测试和植入设备来演示系统的功能和稳定性。该平台应用对显示器产生重大影响的 OLED 技术来构建用于生物研究的变革性光源，该光源能够以几乎任何配置植入，并可用于长时间对大面积的反射率和荧光进行成像。这个轻薄、灵活的平台可以为广泛的成像、光遗传学、荧光测量和其他生物光子应用带来新的视角和功能。该奖项由 BIO 理事会的 IDBR 项目（生物研究仪器开发）和工程理事会的生物光子学项目共同资助。
