SUMMARY:Ramollari\, H. (ECE) - An Optofluidic Spectrometer and Applications in Biosensing
DESCRIPTION:Miniaturized spectrometers have the potential to replace bulky and expensive benchtop models. We have previously demonstrated a multimode interference (MMI) waveguide-based spectrometer that achieves high performance while minimizing its footprint. \nIn this talk\, the integration of the MMI spectrometer into an optofluidic device is proposed. This integration opens up applications such as the detection of single particle fluorescence spectra and absorption spectra. \nMoreover\, adding a metasurface to the spectrometer waveguide is expected to enhance the sensitivity of single particle detection and simplify the analysis methods. \nFinally\, to improve the MMI waveguide spectrometer a new nanophotonic platform is proposed. \nEvent Host: Helio Ramollari\, Ph.D. Student\, Electrical Engineering  \nAdvisor: Holger Schmidt  \nZoom- https://ucsc.zoom.us/j/99623652977?pwd=j2hy77fV9jdGuEzI0iGa5JVAa35W1b.1 \nPasscode- 576057

SUMMARY:Torres\, S. (ECE) - An Integrated Platform for Real-time Monitoring and Support of 3D Tissue Growth
DESCRIPTION:Organoids are three-dimensional tissue cultures that model real organs and serve as valuable tools for studying development\, disease\, and treatment response. Traditional methods\, which rely on manual handling and incubators\, limit consistency and real-time monitoring. To address these issues\, we developed a modular microfluidic platform that integrates automated feeding\, live fluorescence imaging\, and environmental control without the need for a standard incubator. The core of the system is a vertically oriented PDMS-glass chip that enables precise media delivery and continuous imaging of small 3D structures such as organoids. Using fluorescent dyes to mimic molecules\, such as nutrients or drugs\, we tracked their movement through tissue in real time without invasive sensors. This setup maintains metabolic stability and provides detailed insight into molecular transport\, which improves applications in disease modeling\, drug testing\, and personalized medicine. \n  \nEvent Host- Sebastián Torres\, Ph.D. Candidate\, Electrical & Computer Engineering  \nAdvisor: Mircea Teodorescu \n  \nZoom- https://ucsc.zoom.us/j/2333595627?pwd=aWtwL3V2QnFTMkNDSWowZnRNS0xSQT09 \nPasscode- 579836
