תקציר	Contact angle goniometry is a technique for measuring the wettability of a solid surface by determining the angle at which a liquid droplet meets the surface. Rooted in Thomas Young's thermodynamic analysis from 1805, the method uses optical measurement of droplet profile to quantify surface energy and hydrophilicity. It is indispensable in biomaterials characterization, helping researchers assess whether a scaffold or implant surface will promote or inhibit cell adhesion, protein adsorption, and biointegration.	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.	The swelling and degradation assay measures how biomaterial scaffolds absorb water (swelling) and lose mass over time due to degradation. Developed by Wichterle and Lim in 1960 for hydrogels, the assay is fundamental for characterizing hydrogels, synthetic polymers, and composite scaffolds intended for tissue engineering. The assay provides quantitative data on swelling kinetics (equilibrium water content, swelling ratio), degradation kinetics (mass loss rate, half-life), and mechanisms of degradation (chain scission, enzymatic breakdown).
