Sažetak	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.	Dynamic mechanical analysis (DMA) measures the viscoelastic properties of materials—their elastic stiffness and viscous damping—by applying a sinusoidal stress or strain and measuring the phase lag and amplitude of the material's response. Developed from rheology principles in the 1960s and formalized by Ferry, Schwarzl, and others, DMA provides quantitative measures of how polymeric biomaterials respond to time-dependent and frequency-dependent mechanical stimuli. Key outputs include the storage modulus (elastic component), loss modulus (viscous component), and loss tangent (tan δ), which together characterize the material's mechanical behavior across temperature and frequency ranges.	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.
