Borate bioactive glasses (BBGs) are an exciting new type of inorganic material with properties that distinguish them from traditional bioactive glasses [1]. BBGs offer unique benefits for bone and tissue regeneration. Boron enhances bone development, supports cellular functions, and boosts the bioavailability of essential minerals, making these glasses particularly promising for creating materials that not only aid in healing but also actively support critical biological processes. Electrospun fibrous borate glass in the binary oxide system CaO-B₂O₃ is under investigation. The aim of this study is to fabricate highly bioactive glass fibers using a combination of the sol-gel technique and electrospinning and characterize the structure of the obtained materials. The project is a continuation of last year’s internship, as a part of the project OPUS 28+LAP/Weave „Toward a design and customize of borate bioactive glasses – from fundamental composition-structure-properties correlations to advanced 3D structures” between FAU and AGH.
