Modern definition of bioactive glasses and glass-ceramics

open access: yesJournal of Non-Crystalline Solids, 2023
Bioactive glasses (BGs) and glass-ceramics (BGCs) have become a diverse family of materials being applied for treatment of many medical conditions. The traditional understanding of bioactive glasses and glass-ceramics pins them to bone-bonding capability without considering the other fields where they excel, such as soft tissue repair.

Nanodiamond Quantum Sensors for Probing Free Radical Biology

open access: yesAdvanced Functional Materials, EarlyView.
Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.
