Article Synopsis
- - The research discusses the need for non-invasive optical methods to analyze the heterogeneous nature of biological tissues by accurately measuring their local optical properties through specialized probe designs.
- - The aim is to create a theoretical framework for tilted-fiber diffuse reflectance probes that can measure optical properties in small tissue volumes (a few cubic millimeters).
- - Using Monte Carlo simulations, the study establishes connections between probe design, the volume of tissue analyzed, and the effectiveness of the method in calculating optical properties from collected reflectance data.
Article Synopsis
- * The paper's aim is to create a specialized diffuse reflectance probe that can accurately assess the optical properties of these bilayer tissues in a subdiffusive context.
- * Through Monte Carlo simulations, a well-designed probe was developed, achieving less than 20% estimation error in measuring the optical properties of skin layers, which is crucial for early detection of skin-related issues.
Giant unilamellar vesicles (GUVs) are increasingly used as a versatile research tool to investigate membrane structure, morphology and phase state. In these studies, GUV preparation is typically enhanced by an externally applied electric field, a process called electroformation. We find that upon osmotic deflation, GUVs electroformed from charged and neutral lipids exhibit inward pointing lipid nanotubes, suggesting negative spontaneous curvature of the membrane.

Methods: An inflation system to mimic the air variation of the human lungs was constructed. The inflation system was linked to a phantom containing synthetic lungs and an ex vivo human spine.
