Spatially-resolved reflectance spectroscopy with variable fiber geometry
Optical techniques based on spectroscopic analysis have the potential for in vivo detection of early malignancies in tissue. Many optical modalities, including reflectance spectroscopy, use fiber optics as the means of light delivery and detection. However, the influence of fiber geometry on …

Hydrodynamic effects of an arch-shaped fiber optic probe in a dissolution testing apparatus 2
… manual sampling consists in the use of sampling probes, such as fiber optic probes, permanently inserted in the dissolution medium and continually sampling the drug concentration in it as the solid dosage form dissolves. Despite their advantages, permanently inserted fiber optic probes can alter …

Optical spectroscopy for biological and biomedical applications: potentially impacting future of healthcare with research, clinical translation and education
… identify tissue structures with enough contrast. Optical spectroscopy and imaging can solve this insufficiency by providing molecular-sensitive tools for applications involving screening, diagnosis, monitoring vital signs, treatment planning and guidance, treatment-outcome prediction, and others. …
