Modular and Portable Time-Resolved Fluorescence Measurement System

Time-resolved fluorescence measurements are not only able to overcome the limitations of intensity-based applications, but can also resolve information about the sample that is not possible with steady-state data. As monitoring-based preventive medicine becomes more popular, efforts have been made to develop smaller and more affordable measurement methods that could potentially be integrated into point-of-care devices. In

this work, we present a portable, low-cost demonstration device that can perform time-resolved fluorescence measurements in the frequency domain. The device combines the flexibility and advanced measurement modes of a desktop sensor system with the small form factor of a portable point-of-care device. Initial measurements show promising results, but further testing is needed to fully assess the performance of the device.
