In this work, different strategies developed in our group for encapsulating different living organisms - i.e. algae, fungi, bacteria, plants - are presented. These were planned in order to protect the biological species against the toxicity of reagents, as well as osmotic stress induced at high ionic strength. Even most of the work has been carried out with silica or silica-biopolymer hybrids using silicate, silica nanoparticles or silica alkoxydes as precursors, we have explored other oxides, such as zirconia and alumina whose precursors exhibit more detrimental effects. These can be managed in conditions in which the cells are protected.
