Podsumowanie	The bone morphogenetic protein (BMP) release assay measures the kinetics and amount of BMP elution from a biomaterial carrier over time. BMP-2, BMP-6, BMP-7, and BMP-9 are potent osteoinductive growth factors discovered by Marshall Urist in 1965 that trigger bone and cartilage formation. When loaded into scaffolds, hydrogels, or implants, BMPs must be released in a controlled manner to maximize biological effect while minimizing systemic exposure. The release assay quantifies how much BMP is present in the surrounding medium at defined timepoints, enabling optimization of carrier materials and release profiles for bone regeneration and fracture healing applications.	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.
