Raman Microscopy for Early Colorectal Cancer Detection
Early detection is critical in improving outcomes for colorectal cancer, creating a need for sensitive methods that can identify subtle changes in tissue. This research explores how Raman microscopy can characterize biochemical differences in colorectal tissue, demonstrating the potential of molecular-level spectral information for early cancer detection research.
Optical Spectroscopy for Skin Lesion Classification
Optical spectroscopy offers a non-invasive way to investigate differences between healthy and abnormal tissue. This application explores how spectral measurements and machine learning can be used to classify skin lesions, highlighting the potential of spectroscopy as a rapid tool for supporting research into skin cancer detection and tissue analysis.
Wearable NIR Spectroscopy for Monitoring Brain Activity
Could NIR spectroscopy move brain activity monitoring beyond the laboratory? This project from Vladimir Pozdin and Alper Bozkurt combines NIR light sources, optical sensing, onboard electronics, and wireless connectivity into a compact wearable system for real-time monitoring of physiological responses associated with cognitive activity.
