'All optical manipulation of optomechanical surfaces'

该项目的目的是建立一个新的生物光子平台的基础上全光学操纵的光子元表面（PM）在微流体环境。该项目利用PM独特的多功能光子响应及其内在的高机械稳定性，将显微镜工具的足迹缩小几个数量级，并解决与分子和细胞生物学接口的关键基础生物学问题。该项目将由几名博士生和研究人员合作。我的部分项目将涉及工作的全息光学镊子设置用于操纵PM和PM运动检测。这将首先使用象限光电二极管来校准系统，然后构建零差方案多普勒振动计来跟踪膜振荡，最后在膜的顶部设计PM，这将允许通过受控的光散射进行精确的位移跟踪。一旦多普勒振动计开始工作，我还将通过将两个PM连接到一段DNA并将其从中心展开来进行力感测。

The aim of the project is to establish a new biophotonic platform based on the all-optical manipulation of photonic metasurfaces (PMs) in microfluidic environments. The project exploits the uniquely versatile photonic response of PMs and their high intrinsic mechanical stability to scale down of several orders of magnitude the footprint of microscopy tools and to address key fundamental biological questions at the interface with molecular and cell biology.The project will be a collaboration between several PhD student and researchers. My portion of the project will involve working on the holographic optical tweezers setup used to manipulate the PM and the PM motion detection. This will first be done using a quadrant photodiode to calibrate the system, then constructing a homodyne scheme Doppler vibrometer to track the membrane oscillations and finally to design PM on top of the membranes which will allow exact displacement tracing by controlled scattering of light. Once the Doppler vibrometer is operational, I will also work on force sensing by attaching two PM to a piece of DNA and unwinding it from the centre.
