Controlling the Release of Hydrogen Peroxide from Catechol-Based Adhesives Using Silica Nanoparticles

Catechol-based bioadhesives generate hydrogen peroxide (H2O2) as a byproduct during the curing process. H2O2 can have both beneficial and deleterious effects on biological systems depending on its concentration. To control the amount of H2O2 released from catechol-containing polyethylene glycol-based adhesive (PEG-DA), an adhesive was formulated with silica nanoparticles (SiNPs) prepared with increased porosity and acid treatment to increase...
