Microbial spores, such as those from the Gram-positive bacterium Bacillus subtilis have the capacity to absorb substances such as ions, proteins and can be coated with polymers. Furthermore, through genetic engineering, the surface of spores can be decorated with heterologous proteins. SporeHybrids will combine these two properties into a versatile platform that allows to combine various inorganic materials and proteins in order to generate novel catalytic applications and hybrid materials with unique properties.
