Trinity College to Host Ireland’s First "BioBrillouin" Microscope
Trinity College is now home to Ireland’s first and only BioBrillouin microscope. The device is expected to enable strides in the fields of inflammation, cancer, developmental biology, and biomedical materials, among other research areas. Cellular and tissue mechanics are potent regulators of disease, dysfunction and regeneration, and understanding them is thus a major focus of biomedical researchers.

Microscopy Method Images Suspended Cells in 3D Using Optical Tweezers
Optical sectioning (OS) enables 3D bioimaging, but it requires non-optical techniques, like sample adhesion and mechanical scanning, to hold and manipulate cells. In situ living cells may lack mechanical attachment or support, and may experience stress from artificial adhesion. A non-contact solution for OS could broaden the use of 3D imaging to include live cells suspended in high-fluidity environments, like water or air.

Photonics Systems for Human Health Care and Biomedical Research
Tue, Jul 22, 2025 1:00 PM - 2:00 PM EDT
Advanced photonics technologies that allow stable, intimate integration with living organisms will accelerate progress in biomedical research. These systems will also serve as the foundations for new approaches for monitoring and treating diseases. This presentation describes the core concepts in optics, optical materials, devices, and systems for two classes of such technologies: 1) colorimetric, wearable microfluidic systems for capture, storage, and quantitative biomarker analysis of eccrine sweat, and 2) cellular-scale optoelectronic probes for neuroscience studies in small animal models.

Quantum Sensing with Atomic Systems and Reconfigurable Instrumentation
Wed, Jul 23, 2025 1:00 PM - 2:00 PM EDT
Quantum sensing leverages the fundamental quantum behavior of atoms and light to measure weak signals with precision beyond that of classical methods. These measurements make use of trapped ions and cold atoms, and include applications such as magnetic field sensing, optical atomic clocks, and quantum gravimetry. Critical to these techniques are ultra-cold temperatures, coherent quantum control, and sensitive optical readout, which pose significant hardware challenges with regard to laser stabilization, timing, and noise suppression. During this presentation, find out how to generate and detect synchronized RF pulse trains, such as a Ramsey sequence, using a software-defined waveform generator and lock-in amplifier. Plus, see new ways to stabilize your systems with a laser lock box and measure clock stability with a phasemeter, using a reconfigurable suite of instruments in a single device. Finally, in a live demonstration, learn how to deploy these instruments simultaneously for maximum flexibility, and how to use Python to interface with each. Presented by Liquid Instruments.
