Optical techniques are experimental and analytical methods that exploit the generation, manipulation, and detection of electromagnetic radiation in the ultraviolet, visible, and infrared ranges to probe material properties, structures, and dynamics. They encompass approaches such as absorption, fluorescence, Raman and elastic scattering measurements, interferometry, and imaging modalities that rely on well-defined light–matter interactions. These techniques enable quantitative characterization of refractive indices, absorption coefficients, energy level structures, molecular conformations, and nanoscale morphology, often with high spatial and temporal resolution. Optical techniques are widely integrated with spectroscopy, microscopy, and metrology platforms and can be implemented in both far-field and near-field configurations.
Light is fundamental to human life—without it, we'd be hungry, cold and blind. But what if the same light that sustains us could also be used to control and observe parts of cells within our bodies?

Across every cell in the body, molecules are constantly pulling, gripping and releasing under mechanical strain. That force often decides whether a drug sticks to its target, whether a cell holds its shape or whether a disease ...
