We have cloned the silica-forming enzymes, silicateins, from both demosponges (marine and freshwater sponges) and hexactinellid sponges. The recombinant enzymes allow the synthesis of silica under environmentally be

In particular, exceptional levels of resilience, damping capacity, and the ability to dissipate mechanical energy prior to failure have been observed, all these properties greatly exceeding those of synthetic melt-fabricated glass. How these observat

Unconstrained optimization problems,s formed in the biological environment often show unusual physical properties (e.g. strength, degree of hydration) and often have structures that exhibit order on many length scales. Biosilica, found in single cell organisms through to higher plants and primitive animals (sponges), is formed from an
