glasses have an inherent nanoporosity, which means their degradation
rate can be controlled. Bioactive sol-gel derived glasses therefore have
higher degradation rates and higher bioactivity than their melt-quenched
counterparts. The process is flexible to allow processing into spherical
particles, foams or fibres.
