概要	The hemolysis assay is a standard method for evaluating the blood compatibility of biomaterials by quantifying the extent to which a material or substance damages red blood cells (RBCs) and causes hemoglobin release. Codified in standards including ASTM F756 and ISO 10993-4, the hemolysis assay is essential for regulatory approval of blood-contacting devices such as stents, catheters, artificial heart valves, and hemodialysis membranes. The assay provides a simple, quantitative measure of hemolytic potential that correlates with clinical safety.	The chorioallantoic membrane (CAM) assay is a well-established in vivo model for studying angiogenesis (new blood vessel formation) and evaluating the pro- or anti-angiogenic properties of biomaterials, drugs, and bioactive molecules. Developed by Judah Folkman in the 1970s, the assay uses the highly vascularized CAM of developing chick embryos as a platform for implanting test materials and observing vascular response. The CAM provides a transparent, immunologically naive microenvironment with rapid and reproducible neovascularization, making it ideal for screening angiogenic potential and assessing biomaterial biocompatibility.	Electrospinning is an electrostatic fiber fabrication process that uses a high electric field to draw polymer solutions or melts into nanoscale fibers. Developed by Anton Formhals in the 1930s and refined by researchers including Darrell Reneker in the 1990s, the technique has become foundational to biomaterials engineering, enabling the creation of porous scaffolds for tissue engineering and drug delivery systems.
