Cells and tissue are complex materials whose heterogeneity and dynamic changes are principally driven at the micron and sub-micron size scales, with underlying events ranging upwards from microsecond time scales, and measurement also based upon faster photo-electronic events of molecules (eg fluorescent and Raman emission from picosecond to nanosecond timescales). Advances in high energy physics and space research have made possible a fast photon imaging detector with >1000 channels each measuring individual photon arrivals to picosecond temporal sensitivity. We aim to develop and use this imaging detector to capture the high spatial and temporal complexity of cells and tissue. In particular, our objectives concern maximising the photon information available to unravel complex multi-component signals, including within background noise, below the visibility of present measurement and automated platforms, which underlie challenges in quantitative imaging and bioassays of live cells and tissue.

细胞和组织是复杂的材料，其异质性和动态变化主要是在微米和亚微米尺寸尺度上驱动的，其潜在事件的范围从微秒时间尺度上向上范围，并且测量也基于分子的更快的光电动事件（EG荧光和EG荧光和EG荧光和EG荧光和Eg electronic事件拉曼从picsecond到纳秒时标）。高能量物理和空间研究的进步使快速光子成像检测器具有> 1000个通道，每个通道每个都测量了单个光子到达的时间敏感性。我们旨在开发和使用此成像检测器来捕获细胞和组织的高空间和时间复杂性。特别是，我们的目标涉及最大化可用的光子信息，以揭示复杂的多组分信号，包括背景噪声，低于当前测量和自动化平台的可见性，这是​​定量成像和活细胞和组织生物测定的挑战。
