Antimicrobial Properties of Gallium-Infused and Zinc-Infused Bioglasses: A Potential Cure for Coronavirus
… literature supported the use of gallium-infused bioglasses as a way to inhibit bacterial and cancerous tumor growth, but this glass was restricted in how well it could prevent viral replication. These findings, along with other literature supporting the key immunological and antiviral properties …

Biosynthesis of polyhydroxyalkanoates and its medical applications
… for pericardial patch application. Bioactive nanobioglass particles (n-BG) of the type 45S5 Bioglass® were incorporated as a filler in the polymer matrix to form P(3HO)/n-BG composite films. The P(3HO)/n-BG composite films were to be used as a multifunctional wound dressing which would act both as …
