The presented study first investigated the directed biomineralization on globular and fibrillar protein templates. Depending on the morphologies of the protein template, globular, non-globular and fibrillar hybrid silica structures were obtained.
Second, the immobilization of functional proteins by non-directed, random entrapment in silica particles generated by biomineralization-inducing organic molecules was investigated. The methodology presented here utilizes the silica sol-gel technique, where entrapping of an enzyme is achieved randomly throughout the chemical formation of highly porous silica under physiological temperature and pH conditions, avoiding degradation during entrapment. The entrapment of proteins for technical applications leads to a number of advantages compared to free enzymes, such as stabilization, re-usability and rapid reaction quenching by the removal of the enzyme-containing silica particles.
